Applicable standards and reference documentation  
The drives documented in this manual have been developed as system peripherals to the highest standards of  
design and construction. The drives depend on host equipment to provide adequate power and environment  
for optimum performance and compliance with applicable industry and governmental regulations. Special  
attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temper-  
ature regulation. In particular, the drives must be securely mounted to guarantee the specified performance  
characteristics. Mounting by bottom holes must meet the requirements of Section 9.4.  
3.1  
Standards  
The Savvio family complies with Seagate standards as noted in the appropriate sections of this manual and the  
Seagate FC Interface Manual, part number 100293070.  
The drives are recognized in accordance with UL 60950 and CSA 60950 as tested by UL(CSA) and EN60950  
as tested by TUV.  
3.1.1  
Electromagnetic compatibility  
The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to  
use. As such the drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC  
Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communica-  
tions.  
The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides  
reasonable shielding. The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of  
the Canadian Department of Communications when properly packaged; however, it is the user’s responsibility  
to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be  
required if the enclosure does not provide adequate shielding. If the I/O cables are external to the enclosure,  
shielded cables should be used, with the shields grounded to the enclosure and to the host controller.  
3.1.1.1  
Electromagnetic susceptibility  
As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is  
the responsibility of those integrating the drive within their systems to perform those tests required and design  
their system to ensure that equipment operating in the same system as the drive or external to the system  
does not adversely affect the performance of the drive. See Tables 2 through 5, DC power requirements.

3.1.2  
Electromagnetic compliance  
Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking  
and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected sys-  
tem represents the most popular characteristics for test platforms. The system configurations include:  
• Typical current use microprocessor  
• Keyboard  
• Monitor/display  
• Printer  
• Mouse  
Although the test system with this Seagate model complies with the directives/standards, we cannot guarantee  
that all systems will comply. The computer manufacturer or system integrator shall confirm EMC compliance  
and provide the appropriate marking for their product.  
Electromagnetic compliance for the European Union  
If this model has the CE Marking it complies with the European Union requirements of the Electromagnetic  
Compatibility Directive 2004/108/EC as put into place on 20 July 2007.  
Australian C-Tick  
If this model has the C-Tick Marking it complies with the Australia/New Zealand Standard AS/NZ CISPR22 and  
meets the Electromagnetic Compatibility (EMC) Framework requirements of Australia's Spectrum Manage-  
ment Agency (SMA).  
Korean KCC  
If these drives have the Korean Communications Commission (KCC) logo, they comply with KN22 and  
KN61000.  
Taiwanese BSMI  
If this model has the Taiwanese certification mark then it complies with Chinese National Standard, CNS13438.  
3.2  
European Union Restriction of Hazardous Substances (RoHS)  
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical  
substances, including Lead (Pb), in electronic products effective July 2006.  
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the rep-  
resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our  
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document  
their compliance with our requirements by providing material content declarations for all parts and materials for  
the disk drives documented in this publication. Current supplier declarations include disclosure of the inclusion  
of any RoHS-regulated substance in such parts or materials.  
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws  
and regulations which restrict chemical content in electronic products. These systems include standard operat-  
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora-  
tory analytical validation testing, and an internal auditing process to ensure that all standard operating  
procedures are complied with.

General description  
Savvio 10K.5 FC drives provide high performance, high capacity data storage for a variety of systems including  
engineering workstations, network servers, mainframes, and supercomputers. Savvio 10K.5 FC drives support  
4-Gb Fibre Channel which can transfer data at up to 800MBs per second and 1600MBs per second in dual-  
loop configurations.  
Savvio 10K.5 FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol  
as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual which  
describes the general interface characteristics of this drive. Savvio 10K.5 FC drives are classified as intelligent  
peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.  
Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actuator,  
etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any  
reason voids your warranty.  
Savvio drives use a dedicated load/unload zone at the outermost radius of the media to eliminate the possibil-  
ity of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/  
unload when power is removed from the drive.  
An automatic shipping lock prevents potential damage to the heads and disks that results from movement dur-  
ing shipping and handling. The shipping lock disengages and the head load process begins when power is  
applied to the drive.  
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm  
design that provides excellent performance with minimal power dissipation.

Formatted capacities  
Standard OEM models are formatted to 512 bytes per block. The sector size is selectable at format time. Users  
having the necessary equipment may modify the data block size before issuing a format command and obtain  
different formatted capacities than those listed.  
To provide a stable target capacity environment and at the same time provide users with flexibility if they  
choose, Seagate recommends product planning in one of two modes:  
1. Seagate designs specify capacity points at certain sector sizes that Seagate guarantees current and future  
products will meet. We recommend customers use this capacity in their project planning, as it ensures a  
stable operating point with backward and forward compatibility from generation to generation. The current  
guaranteed operating points for this product are:

2. Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess  
capacity above the guaranteed level will vary between 10K and 15K families and from generation to gener-  
ation, depending on how each sector size actually formats out for zone frequencies and splits over servo  
bursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities  
listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user  
must determine if the extra capacity potential is useful, or whether their assurance of backward and for-  
ward compatibility takes precedence.

Programmable drive capacity  
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the  
Mode Select Parameter List table in the SCSI Commands Reference Manual. Refer to the Parameter list block  
descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not  
change the capacity it is currently formatted to have. A number in the number of blocks field that is less than  
the maximum number of LBAs changes the total drive capacity to the value in the block descriptor number of  
blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.  
4.7  
Factory-installed options  
You may order the following items which are incorporated at the manufacturing facility during production or  
packaged before shipping. Some of the options available are (not an exhaustive list of possible options):  
• Other capacities can be ordered depending on sparing scheme and sector size requested.  
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection  
against transit damage. Units shipped individually require additional protection as provided by the single unit  
shipping pack. Users planning single unit distribution should specify this option.  
• The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each  
standard OEM drive shipped, but extra copies may be ordered.

5.3  
Start/stop time  
If the Motor Start option is disabled, the drive becomes ready within 20 seconds after DC power is applied. If a  
recoverable error condition is detected during the start sequence, the drive executes a recovery procedure and  
the time to become ready may exceed 20 seconds. During spin up to ready time, the drive responds to some  
commands over the FC interface in less than 3 seconds after application of power. Stop time is 30 seconds  
(maximum) from removal of DC power.  
If the Motor Start option is enabled, the internal controller accepts the commands listed in the Fibre Channel  
Interface Manual less than 3 seconds after DC power has been applied. After the Motor Start command has  
been received, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery  
procedure). The Motor Start command can also be used to command the drive to stop the spindle.  
There is no power control switch on the drive.  
5.4  
Prefetch/multi-segmented cache control  
The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many  
cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in  
cache operations. To select this feature, the host sends the Mode Select command with the proper values in  
the applicable bytes in page 08h. Prefetch and cache operations are independent features from the standpoint  
that each is enabled and disabled independently using the Mode Select command; however, in actual opera-  
tion, the prefetch feature overlaps cache operation somewhat as described in sections 5.5.1 and 5.5.2.  
All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this  
drive family are given in Section 10.3.2  
Savvio 10K.5 FC Product Manual, Rev. D  
11  
                       
5.5  
Cache operation  
Note. Refer to the Fibre Channel Interface Manual for more detail concerning the cache bits.  
Of the 64 Mbytes physical buffer space in the drive, approximately 30,000 kbytes are available as a data  
cache. The remaining buffer space is reserved for internal drive use.  
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the  
cache is enabled (see RCD bit in the FC Interface Manual), data requested by the host with a read command  
is retrieved from the buffer, if possible, before any disk access is initiated. If cache operation is not enabled, the  
buffer is still used, but only as circular buffer segments during disk medium read operations (disregarding  
Prefetch operation for the moment). That is, the drive does not check in the buffer segments for the requested  
read data, but goes directly to the medium to retrieve it. The retrieved data merely passes through some buffer  
segment on the way to the host. All data transfers to the host are in accordance with buffer-full ratio rules. See  
the explanation provided with the information about Mode Page 02h (disconnect/reconnect control) in the Fibre  
Channel Interface Manual.  
The following is a simplified description of the prefetch/cache operation:  
Case A—read command is received and all of the requested logical blocks are already in the cache:  
1. Drive transfers the requested logical blocks to the initiator.  
Case B—A Read command requests data, and at least one requested logical block is not in any segment of  
the cache:  
1. The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then  
from there to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.  
2. If the prefetch feature is enabled, refer to section 5.5.2 for operation from this point.  
Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical  
blocks. The drive dynamically creates and removes segments based on the workload. The wrap-around capa-  
bility of the individual segments greatly enhances the cache’s overall performance.  
Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF  
is always reported regardless of the actual size of the segment. Sending a size specification using the Mode  
Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte  
2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable parameter.

Savvio 10K.5 FC Product Manual, Rev. D  
         
5.5.1  
Caching write data  
Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to  
be written to the medium is stored while the drive performs the Write command.  
If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made avail-  
able for future read cache hits. The same buffer space and segmentation is used as set up for read functions.  
The buffer segmentation scheme is set up or changed independently, having nothing to do with the state of  
RCD. When a write command is issued, if RCD=0, the cache is first checked to see if any logical blocks that  
are to be written are already stored in the cache from a previous read or write command. If there are, the  
respective cache segments are cleared. The new data is cached for subsequent Read commands.  
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the  
segment is reached, the data is written into the beginning of the same cache segment, overwriting the data that  
was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet  
been written to the medium.  
If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data  
has been transferred into the cache, but before the data has been written to the medium. If an error occurs  
while writing the data to the medium, and Good status has already been returned, a deferred error will be gen-  
erated.  
The Synchronize Cache command may be used to force the drive to write all cached write data to the medium.  
Upon completion of a Synchronize Cache command, all data received from previous write commands will have  
been written to the medium.  
Tables 19 through 22 show the mode default settings for these drives.  
5.5.2  
Prefetch operation  
If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which  
was requested by a Read command are retrieved and stored in the buffer for immediate transfer from the buf-  
fer to the host on subsequent Read commands that request those logical blocks (this is true even if cache  
operation is disabled). Though the prefetch operation uses the buffer as a cache, finding the requested data in  
the buffer is a prefetch hit, not a cache operation hit.  
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0  
enables prefetch.  
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11).  
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous  
blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it  
decides that a prefetch hit is not likely to occur.

Error rates  
The error rates stated in this manual assume the following:  
• The drive is operated in accordance with this manual using DC power as defined in Section 7.3  
• Errors caused by host system failures are excluded from error rate computations.  
• Assume random data.  
• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write  
retries and full retry time.  
6.1.1  
Recoverable Errors  
Recoverable errors are those detected and corrected by the drive, and do not require user intervention.  
Recoverable Data errors will use Error Correction when needed.  
Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a  
read, and using write bits transferred for recoverable errors occurring during a write.  
6.1.2  
Unrecoverable Errors  
16  
Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 10 bits trans-  
ferred. Unrecoverable Data Errors resulting from the same cause are treated as 1 error for that block.

6.1.3  
Seek errors  
A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an  
initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails,  
a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense  
8
Key. Recoverable seek errors are specified at Less than 10 errors in 10 seeks. Unrecoverable seek errors  
(Sense Key = 04h) are classified as drive failures.  
6.1.4  
Interface errors  
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the  
device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss  
of word sync, or CRC error. The total error rate for a loop of devices is the sum of the individual device error  
rates.  
6.2  
Reliability and service  
You can enhance the reliability of disk drives by ensuring that the drive receives adequate cooling. Section 7.0  
provides temperature measurements and other information that may be used to enhance the service life of the  
drive. Section 9.2 provides recommended air-flow information.  
6.2.1  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
These drives shall achieve an AFR of 0.44% (MTBF of 2,000,000 hours) when operated in an environment that  
ensures the HDA case temperatures do not exceed the values specified in Section 7.5.1.  
Operation at case temperatures outside the specifications in Section 7.5.1 may increase the AFR (decrease  
the MTBF).  
AFR and MTBF statistics are population statistics that are not relevant to individual units. AFR and MTBF spec-  
ifications are based on the following assumptions for Enterprise Storage System environments:  
• 8,760 power-on hours per year  
• 250 average on/off cycles per year  
• Operating at nominal voltages  
• System provides adequate cooling to ensure the case temperatures specified in Section 7.5.1 are not  
exceeded.  
6.2.2  
Preventive maintenance  
No routine scheduled preventive maintenance is required.  
6.2.3  
Hot plugging the drive  
Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the  
receiver of the next device in the loop must synchronize to a different input signal. FC error detection mecha-  
nisms, character sync, running disparity, word sync, and CRC are able to detect any error. Recovery is initiated  
based on the type of error.  
The disk drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching  
the power or hot plugged. The control line to an optional port bypass circuit (external to the drive), defaults to  
the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the  
output of the previous device to the newly inserted device. If the bypass circuit is not present, loop operation is  
temporarily disrupted until the next device starts receiving the output from the newly inserted device and  
regains synchronization to the new input.  
Savvio 10K.5 FC Product Manual, Rev. D  
15  
                                                 
The Pass-through state is disabled while the drive performs self test of the FC interface. The control line for an  
external port bypass circuit remains in the Enable Bypass state while self test is running. If the bypass circuit is  
present, loop operation may continue. If the bypass circuit is not present, loop operation will be halted while the  
self test of the FC interface runs.  
When the self test completes successfully, the control line to the bypass circuit is disabled and the drive enters  
the FC-AL Initializing state. The receiver on the next device in the loop must synchronize to output of the newly  
inserted drive.  
If the self-test fails, the control line to the bypass circuit remains in the Enable Bypass state.  
Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard, or ESD poten-  
tial hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from the drive  
carrier prior to inserting it into the system.  
Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is  
required to insure data integrity.  
6.2.4  
S.M.A.R.T.  
S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended  
to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a  
failure to allow you to back up the data before an actual failure occurs.  
Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive fail-  
ures.  
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating per-  
formance of the drive and the thresholds are optimized to minimize “false” and “failed” predictions.  
Controlling S.M.A.R.T.  
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions  
Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEX-  
CPT bit disables all S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs  
normal read and write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode  
Only” and will not perform off-line functions.  
You can measure off-line attributes and force the drive to save the data by using the Rezero Unit command.  
Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.  
You can interrogate the drive through the host to determine the time remaining before the next scheduled mea-  
surement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E.  
This allows you to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command  
resets the timer.  
Performance impact  
S.M.A.R.T. attribute data is saved to the disk so that the events that caused a predictive failure can be recre-  
ated. The drive measures and saves parameters once every hour subject to an idle period on the FC-AL bus.  
The process of measuring off-line attribute data and saving data to the disk is interruptable. The maximum on-  
line only processing delay is summarized below:

75 ms  
16  
Savvio 10K.5 FC Product Manual, Rev. D  
     
Reporting control  
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to  
the reporting method. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00  
sense code. The FRU field contains the type of predictive failure that occurred. The error code is preserved  
through bus resets and power cycles.  
Determining rate  
S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors  
increases to an unacceptable level. To determine rate, error events are logged and compared to the number of  
total operations for a given attribute. The interval defines the number of operations over which to measure the  
rate. The counter that keeps track of the current number of operations is referred to as the Interval Counter.  
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of  
the number of errors for the current interval. This counter is referred to as the Failure Counter.  
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to  
set thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before  
the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed  
the threshold before the interval expires, the error rate is considered to be acceptable. In either case, the inter-  
val and failure counters are reset and the process starts over.  
Predictive failures  
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firm-  
ware keeps a running count of the number of times the error rate for each attribute is unacceptable. To accom-  
plish this, a counter is incremented each time the error rate is unacceptable and decremented (not to exceed  
zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the pre-  
dictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter.  
There is a separate Failure History Counter for each attribute.  
6.2.5  
Thermal monitor  
Savvio 10K.5 FC drives implement a temperature warning system which:  
1. Signals the host if the temperature exceeds a value which would threaten the drive.  
2. Signals the host if the temperature exceeds a user-specified value.  
3. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.  
A temperature sensor monitors the drive temperature and issues a warning over the interface when the tem-  
perature exceeds a set threshold. The temperature is measured at power-up and then at ten-minute intervals  
after power-up.  
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the speci-  
fied limit in compliance with the SCSI standard. The drive temperature is reported in the FRU code field of  
mode sense data. You can use this information to determine if the warning is due to the temperature exceeding  
the drive threatening temperature or the user-specified temperature.  
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the  
Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC)  
mode page (1Ch).  
The current algorithm implements two temperature trip points. The first trip point is set at 68°C which is the  
maximum temperature limit according to the drive specification. The second trip point is user-selectable using  
the Log Select command. The reference temperature parameter in the temperature log page (see Table 1) can  
Savvio 10K.5 FC Product Manual, Rev. D  
17  
 
be used to set this trip point. The default value for this drive is 68°C, however, you can set it to any value in the  
range of 0 to 68°C. If you specify a temperature greater than 68°C in this field, the temperature is rounded  
down to 68°C. A sense code is sent to the host to indicate the rounding of the parameter field.

6.2.6  
Drive Self Test (DST)  
Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a  
failed unit. DST validates the functionality of the drive at a system level.  
There are two test coverage options implemented in DST:  
1. Extended test  
2. Short test  
The most thorough option is the extended test that performs various tests on the drive and scans every logical  
block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the  
entire media surface, but does some fundamental tests and scans portions of the media.  
If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test,  
remove it from service and return it to Seagate for service.  
6.2.6.1  
DST failure definition  
The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log  
page if a functional failure is encountered during DST. The channel and servo parameters are not modified to  
test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes  
are enabled during the test. If data is recoverable, no failure condition will be reported regardless of the number  
of retries required to recover the data.  
The following conditions are considered DST failure conditions:  
• Seek error after retries are exhausted  
• Track-follow error after retries are exhausted  
• Read error after retries are exhausted  
• Write error after retries are exhausted  
Recovered errors will not be reported as diagnostic failures.  
6.2.6.2  
Implementation  
This section provides all of the information necessary to implement the DST function on this drive.  
6.2.6.2.1  
State of the drive prior to testing  
The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons  
why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be  
in process of doing a format, or another DST. It is the responsibility of the host application to determine the “not  
ready” cause.  
While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a  
failed drive.  
18  
Savvio 10K.5 FC Product Manual, Rev. D  
 
A Drive Not Ready condition is reported by the drive under the following conditions:  
• Motor will not spin  
• Motor will not lock to speed  
• Servo will not lock on track  
• Drive cannot read configuration tables from the disk  
In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.  
6.2.6.2.2  
Invoking DST  
To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short  
test or 010b for the extended test) in bytes 1, bits 5, 6, and 7.  
6.2.6.2.3  
Short and extended tests  
DST has two testing options:  
1. short  
2. extended  
These testing options are described in the following two subsections.  
Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan  
segment.  
Short test (Function Code: 001b)  
The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within  
120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and  
scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a  
fault condition. This option provides a quick confidence test of the drive.  
Extended test (Function Code: 010b)  
The objective of the extended test option is to empirically test critical drive components. For example, the seek  
tests and on-track operations test the positioning mechanism. The read operation tests the read head element  
and the media surface. The write element is tested through read/write/read operations. The integrity of the  
media is checked through a read/verify scan of the media. Motor functionality is tested by default as a part of  
these tests.  
The anticipated length of the Extended test is reported through the Control Mode page.  
6.2.6.2.4  
Log page entries  
When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created  
by inserting a new self-test parameter block at the beginning of the self-test results log parameter section of the  
log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 param-  
eter blocks in the log page. If there are more than 20 parameter blocks, the least recent parameter block will be  
deleted. The new parameter block will be initialized as follows:  
1. The Function Code field is set to the same value as sent in the DST command  
2. The Self-Test Results Value field is set to Fh  
3. The drive will store the log page to non-volatile memory  
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-  
Test Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the  
last 20 self-tests performed by the drive. The self-test results value is a 4-bit field that reports the results of the  
test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero,  
the test failed for the reason reported in the field.  
Savvio 10K.5 FC Product Manual, Rev. D  
19  
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The  
Sense key, ASC, ASCQ, and FRU are used to report the failure condition.  
6.2.6.2.5  
Abort  
There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message  
to abort the diagnostic.  
You can abort a DST executing in background mode by using the abort code in the DST Function Code field.  
This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values  
log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).  
6.2.7  
Product warranty  
Beginning on the date of shipment to the customer and continuing for the period specified in your purchase  
contract, Seagate warrants that each product (including components and subassemblies) that fails to function  
properly under normal use due to defect in materials or workmanship or due to nonconformance to the applica-  
ble specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned  
by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty  
procedure. Seagate will pay for transporting the repair or replacement item to the customer. For more detailed  
warranty information, refer to the standard terms and conditions of purchase for Seagate products on your pur-  
chase documentation.  
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at  
1-800-468-3472. You can also determine remaining warranty using the Seagate web site (www.seagate.com).  
The drive serial number is required to determine remaining warranty information.  
Shipping  
When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Sea-  
gate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a  
non-approved container voids the drive warranty.  
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran-  
sit. Contact your authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping  
by an air-ride carrier experienced in handling computer equipment.  
Product repair and return information  
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does  
not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids  
the warranty.  
Storage  
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives  
should be stored in the original unopened Seagate shipping packaging when ever possible. Once the drive is  
removed from the Seagate original packaging the recommended maximum period between drive operation  
cycles is 30 days. During any storage period the drive non-operational temperature, humidity, wet bulb, atmo-  
spheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

PowerChoiceTM power management  
Drives using the load/unload architecture provide programmable power management to tailor systems for per-  
formance and greater energy efficiency.  
The table below lists the supported PowerChoice modes. The further you go down in the table, the more power  
savings you get. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby  
modes results in the greatest power savings.

PowerChoice can be invoked using one of these two methods:  
• Power Condition mode page method—Enable and initialize the idle condition timers and/or the standby con-  
dition timers. The timer values are based on the values set in the Power Condition mode page.  
• START STOP UNIT command method—Use the START STOP UNIT command (OPERATION CODE 1Bh).  
This allows the host to directly transition the drive to any supported PowerChoice mode.  
If both the Power Condition mode page and START STOP UNIT command methods are used, the START  
STOP UNIT command request takes precedence over the Power Condition mode page power control and may  
disable the idle condition and standby condition timers. The REQUEST SENSE command reports the current  
PowerChoice state if active and also the method by which the drive entered the PowerChoice state.  
When the drive receives a command, all power condition timers are suspended if they were enabled via the  
Power Condition mode page. Once all outstanding commands are processed, the power condition timers are  
reinitialized to the values defined in the Power Condition mode page.

[1] Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power  
supply at nominal voltage. N (number of drives tested) = 6, 35 Degrees C ambient.  
[2] For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 9,936 RPM.  
The ±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the  
drive is able to accept selection by the host initiator.

General DC power requirement notes.  
1. Minimum current loading for each supply voltage is not less than 1.2% of the maximum operating current  
shown.  
2. The +5V and +12V supplies should employ separate ground returns.  
3. Where power is provided to multiple drives from a common supply, careful consideration for individual  
drive power requirements should be noted. Where multiple units are powered on simultaneously, the peak  
starting current must be available to each device.  
4. Parameters, other than spindle start, are measured after a 25-minute warm up.  
5. No terminator power.  
7.3.1  
Conducted noise immunity  
Noise is specified as a periodic and random distribution of frequencies covering a defined frequency. Maximum  
allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.  
+5 V = 250 mV pp from 0 to 100 Hz to 20 MHz.  
+12 V = 450 mV pp from 100 Hz to 100 KHz.  
250 mV pp from 100 KHz to 20 MHz.  
150 mV pp from 20 MHz to 80 MHz.

Environmental limits  
Temperature and humidity values experienced by the drive must be such that condensation does not occur on  
any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F  
(14.8°C). Maximum wet bulb temperature is 82°F (28°C).  
Note. To maintain optimal performance drives should be run at nominal case temperatures.  
7.5.1  
Temperature  
a. Operating  
The drive meets the operating specifications over a 41°F to 131°F (5°C to 55°C) drive case temperature  
range with a maximum temperature gradient of 36°F (20°C) per hour.  
The maximum allowable drive case temperature is 60°C.  
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal  
case temperature. The rated MTBF is based upon a sustained case temperature of 122°F (50°C). Occa-  
sional excursions in operating temperature between the rated MTBF temperature and the maximum drive  
operating case temperature may occur without impact to the rated MTBF temperature. However continual or  
sustained operation at case temperatures beyond the rated MTBF temperature will degrade the drive MTBF  
and reduce product reliability.  
Air flow may be required to achieve consistent nominal case temperature values (see Section 9.2). To con-  
firm that the required cooling is provided for the electronics and HDA, place the drive in its final mechanical  
configuration, and perform random write/read operations. After the temperatures stabilize, measure the  
case temperature of the drive.  
b. Non-operating  
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This  
specification assumes that the drive is packaged in the shipping container designed by Seagate for use with  
drive.

Relative humidity  
The values below assume that no condensation on the drive occurs.  
a. Operating

7.5.4  
Shock and vibration  
Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is  
installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur  
internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent,  
it may be necessary to modify the enclosure to minimize drive movement.  
The limits of shock and vibration defined within this document are specified with the drive mounted by any of  
the four methods shown in Figure 9, and in accordance with the restrictions of Section 9.4.  
7.5.4.1  
Shock  
a. Operating—normal  
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not  
exceeding:  
• 15 Gs at a duration of 11ms (half sinewave)  
• 25 Gs at a duration of 2ms (half sinewave)  
• 65 Gs at a duration of 2ms (half sinewave) when performing reads only  
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.  
b. Non-operating  
The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes  
both isolated drives and integrated drives.  
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device  
damage or performance degradation.  
• 80 Gs at a duration of 11ms (half sinewave)  
• 400 Gs at a duration of 2ms (half sinewave)  
• 300 Gs at a duration of 0.5ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis.  
c. Packaged  
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM  
standards. Volume finished drives will be shipped from Seagate factories on pallets to minimize freight  
costs and ease material handling. Seagate finished drive bulk packs may be shipped individually. For less  
than full shipments, instructions are printed on the bulk pack carton for minimum drive quantities and proper  
drive placement.

7.5.7  
Corrosive environment  
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to  
light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM  
B845. However, this accelerated testing cannot duplicate every potential application environment.  
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corro-  
sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-  
ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,  
chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components  
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or  
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulca-  
nized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any  
electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

Defect and error management  
Seagate continues to use innovative technologies to manage defects and errors. These technologies are  
designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation.  
SCSI defect and error management involves drive internal defect/error management and FC system error con-  
siderations (errors in communications between the initiator and the drive). In addition, Seagate provides the  
following technologies used to increase data integrity and drive reliability:  
• Background Media Scan (see Section 8.4)  
• Media Pre-Scan (see Section 8.5)  
• Deferred Auto-Reallocation (see Section 8.6)  
• Idle Read After Write (see Section 8.7)  
The read error rates and specified storage capacities are not dependent on host (initiator) defect management  
routines.  
8.1  
Drive internal defects/errors  
During the initial drive format operation at the factory, media defects are identified, tagged as being unusable,  
and their locations recorded on the drive primary defects list (referred to as the “P’ list and also as the ETF  
defect list). At factory format time, these known defects are also reallocated, that is, reassigned to a new place  
on the medium and the location listed in the defects reallocation table. The “P” list is not altered after factory  
formatting. Locations of defects found and reallocated during error recovery procedures after drive shipment  
are listed in the “G” list (defects growth list). The “P” and “G” lists may be referenced by the initiator using the  
Read Defect Data command.  
Details of the SCSI commands supported by the drive are described in the Fibre Channel Interface Manual.  
Also, more information on the drive Error Recovery philosophy is presented in the Fibre Channel Interface  
Manual.  
8.2  
Drive error recovery procedures  
When an error occurs during drive operation, the drive, if programmed to do so, performs error recovery proce-  
dures to attempt to recover the data. The error recovery procedures used depend on the options previously set  
in the Error Recovery Parameters mode page. Error recovery and defect management may involve using sev-  
eral SCSI commands described in the SCSI Interface Manual. The drive implements selectable error recovery  
time limits required in video applications.  
The error recovery scheme supported by the drive provides a way to control the total error recovery time for the  
entire command in addition to controlling the recovery level for a single LBA. The total amount of time spent in  
error recovery for a command can be limited using the Recovery Time Limit bytes in the Error Recovery mode  
page. The total amount of time spent in error recovery for a single LBA can be limited using the Read Retry  
Count or Write Retry Count bytes in the Error Recovery mode page.  
42  
Savvio 10K.5 FC Product Manual, Rev. D  
                 
The drive firmware error recovery algorithms consist of 20 levels for read recoveries and five levels for write.  
Each level may consist of multiple steps, where a step is defined as a recovery function involving a single re-  
read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and  
write retry counts.  
Table 6 equates the read and write retry count with the maximum possible recovery time for read and write  
recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations  
are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recov-  
ery time limit for the command has not yet been met. Time needed to perform reallocation is not counted  
against the recovery time limit.  
When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still  
perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and  
Recovery Time Limit parameters. However, the drive does not report any unrecovered errors.

e.g. 1 ~ 5%  
5 ~ 25%  
20 ~ 100%  
Setting these retry counts to a value below the default setting could result in degradation of the unrecovered  
error rate. For example, suppose the read/write recovery page has the RC bit = 0 and if the read retry count is  
set to 5, this means ~ 25% of error recovery will be executed which consumes 621.62 ms (please refer to the  
table above). If the limit is reached and a LBA has not yet been recovered (i.e. requires retries beyond 621.62  
ms), the command will end with Check Condition status report and unrecoverable read error will be reported.  
8.3  
FC-AL system errors  
Information on the reporting of operational errors or faults across the interface is given in the Fibre Channel  
Interface Manual. The FCP Response returns information to the host about numerous kinds of errors or faults.  
The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive.  
Status returned by the drive to the initiator is described in the Fibre Channel Interface Manual. Status reporting  
plays a role in systems error management and its use in that respect is described in sections where the various  
commands are discussed.

8.4  
Background Media Scan  
Background Media Scan (BMS) is a self-initiated media scan. BMS is defined in the T10 document SPC-4  
available from the T10 committee. BMS performs sequential reads across the entire pack of the media while  
the drive is idle. In RAID arrays, BMS allows hot spare drives to be scanned for defects prior to being put into  
service by the host system. On regular duty drives, if the host system makes use of the BMS Log Page, it can  
avoid placing data in suspect locations on the media. Unreadable and recovered error sites will be logged or  
reallocated per ARRE/AWRE settings.  
With BMS, the host system can consume less power and system overhead by only checking BMS status and  
results rather than tying up the bus and consuming power in the process of host-initiated media scanning activ-  
ity.  
Since the background scan functions are only done during idle periods, BMS causes a negligible impact to sys-  
tem performance. The first BMS scan for a newly manufactured drive is performed as quickly as possible to  
verify the media and protect data by setting the “Start time after idle” to 5ms, all subsequent scans begin after  
500ms of idle time. Other features that normally use idle time to function will function normally because BMS  
functions for bursts of 800ms and then suspends activity for 100ms to allow other background functions to  
operate.  
BMS interrupts immediately to service host commands from the interface bus while performing reads. BMS will  
complete any BMS-initiated error recovery prior to returning to service host-initiated commands. Overhead  
associated with a return to host-servicing activity from BMS only impacts the first command that interrupted  
BMS, this results in a typical delay of about 1ms.  
8.5  
Media Pre-Scan  
Media Pre-Scan is a feature that allows the drive to repair media errors that would otherwise have been found  
by the host system during critical data accesses early in the drive’s life. The default setting for Media Pre-Scan  
is enabled on standard products. Media Pre-Scan checks each write command to determine if the destination  
LBAs have been scanned by BMS. If the LBAs have been verified, the drive proceeds with the normal write  
command. If the LBAs have not been verified by BMS, Pre-Scan will convert the write to a write verify to certify  
that the data was properly written to the disk.  
Note. During Pre-Scan write verify commands, write performance may decrease by 50% until Pre-Scan completes. Write  
performance testing should be performed after Pre-Scan is complete. This may be checked by reading the BMS  
status.  
To expedite the scan of the full pack and subsequently exit from the Pre-Scan period, BMS will begin scanning  
immediately when the drive goes to idle during the Pre-Scan period. In the event that the drive is in a high  
transaction traffic environment and is unable to complete a BMS scan within 24 power on hours BMS will dis-  
able Pre-Scan to restore full performance to the system.  
8.6  
Deferred Auto-Reallocation  
Deferred Auto-Reallocation (DAR) simplifies reallocation algorithms at the system level by allowing the drive to  
reallocate unreadable locations on a subsequent write command. Sites are marked for DAR during read oper-  
ations performed by the drive. When a write command is received for an LBA marked for DAR, the auto-reallo-  
cation process is invoked and attempts to rewrite the data to the original location. If a verification of this rewrite  
fails, the sector is re-mapped to a spare location.  
This is in contrast to the system having to use the Reassign Command to reassign a location that was unread-  
able and then generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE  
are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is  
unable to reallocate the failing location and will report an error sense code indicating that a write command is  
being attempted to a previously failing location.

8.7  
Idle Read After Write  
Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods,  
no active system requests, the drive reads recently written data from the media and compares it to valid write  
command data resident in the drives data buffer. Any sectors that fail the comparison result in the invocation of  
a rewrite and auto-reallocation process. The process attempts to rewrite the data to the original location. If a  
verification of this rewrite fails, the sector is re-mapped to a spare location.  
8.8  
Protection Information (PI)  
Protection Information is intended as a standardized approach to system level LRC traditionally provided by  
systems using 520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA  
count (i.e. same capacity point) as non-PI formatted drives. Sequential performance of a PI drive will be  
reduced by approximately 1.56% due to the extra overhead of PI being transferred from the media that is not  
calculated as part of the data transferred to the host. To determine the full transfer rate of a PI drive, transfers  
should be calculated by adding the 8 extra bytes of PI to the transferred LBA length, i.e. 512 + 8 = 520. PI for-  
matted drives are physically formatted to 520 byte sectors that store 512 bytes of customer data with 8 bytes of  
Protection Information appended to it. The advantage of PI is that the Protection Information bits can be man-  
aged at the HBA and HBA driver level. Allowing a system that typically does not support 520 LBA formats to  
integrate this level of protection.  
Protection Information is valid with any supported LBA size. 512 LBA size is used here as common example.  
8.8.1  
Levels of PI  
There are 4 types of Protection Information.  
Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-  
PI systems.  
Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WRTPRO-  
TECT bits allow for checking control through the CDB. Eight bytes of Protection Information are transmitted at  
LBA boundaries across the interface if RDPROTECT and WRTPROTECT bits are nonzero values. Type 1  
does not allow the use of 32 byte commands.  
Type 2 - Provides checking control and additional expected fields within the 32 byte CDBs. Eight bytes of Pro-  
tection Information are transmitted at LBA boundaries across the interface if RDPROTECT and WRTPRO-  
TECT bits are nonzero values. Type 2 does allow the use of 10 and 16 byte commands with zero values in the  
RDPROTECT and WRTPROTECT fields. The drive will generate 8 bytes (e.g.0xFFFF) 8 bytes of Protection  
Information to be stored on the media, but the 8 bytes will not be transferred to the host during a read com-  
mand.  
Type 3 - Seagate products do not support Type 3.  
8.8.2  
Setting and determining the current Type Level  
A drive is initialized to a type of PI by using the format command on a PI capable drive. Once a drive is format-  
ted to a PI Type, it may be queried by a Read Capacity (16) command to report the PI type which it is currently  
formatted to. PI Types cannot coexist on a single drive. A drive can only be formatted to a single PI Type. It can  
be changed at anytime to a new Type but requires a low level format which destroys all existing data on the  
drive. No other vehicle for changing the PI type is provided by the T10 SBC3 specification.  
Type 1 PI format CDB command: 04 90 00 00 00 00, Write Buffer: 00 A0 00 00  
Type 2 PI format CDB command: 04 D0 00 00 00 00, Write Buffer: 00 A0 00 00

Identifying a Protection Information drive  
The Standard Inquiry provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page  
0x86 provides bits to indicate the PI Types supported and which PI fields the drive supports checking.

Installation  
Savvio 10K.5 FC disk drive installation is a plug-and-play process. There are no jumpers, switches, or termina-  
tors on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA) no  
cables are required. See Section 10.5 for additional information about this connector.  
Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.  
If multiple devices are on the same FC-AL and physical addresses are used, set the device selection IDs (SEL  
IDs) on the backpanel so that no two devices have the same selection ID. This is called the hard assigned arbi-  
trated loop physical address (AL_PA). There are 125 AL_PAs available (see Table 28). If you set the AL_PA on  
the backpanel to any value other than 0, the device plugged into the backpanel’s SCA connector inherits this  
AL_PA. In the event you don’t successfully assign unique hard addresses (and therefore have duplicate selec-  
tion IDs assigned to two or more devices), the FC-AL generates a message indicating this condition. If you set  
the AL_PA on the backpanel to a value of 0, the system issues a unique soft-assigned physical address auto-  
matically.  
Loop initialization is the process used to verify or obtain an address. The loop initialization process is per-  
formed when power is applied to the drive, when a device is added or removed from the Fibre Channel loop, or  
when a device times out attempting to win arbitration.  
• Set all option selections in the connector prior to applying power to the drive. If you change options after  
applying power to the drive, recycle the drive power to activate the new settings.  
• It is not necessary to low-level format this drive. The drive is shipped from the factory low-level formatted in  
512-byte logical blocks. You need to reformat the drive only if you want to select a different logical block size.  
9.1  
Drive ID/option selection  
All drive options are made through the interface connector (J1). Table 25 provides the pin descriptions for the  
40-pin Fibre Channel single connector (J1).  
9.2  
Drive orientation  
The drive may be mounted in any orientation. All drive performance characterizations, however, have been  
done with the drive in horizontal (disks level) and vertical (drive on its side) orientations, which are the two pre-  
ferred mounting orientations.  
9.3  
Cooling  
The host enclosure must dissipate heat from the drive. You should confirm that the host enclosure is designed  
to ensure that the drive operates within the temperature measurement guidelines described in Section 7.5.1. In  
some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in  
Savvio 10K.5 FC Product Manual, Rev. D  
47  
                                                     
If forced air is necessary, possible air-flow patterns are shown in Figure 11. The air-flow patterns are created by  
fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow  
patterns are acceptable as long as the temperature measurement guidelines of Section 7.5.1 are met.

9.4  
Drive mounting  
Mount the drive using the bottom or side mounting holes. If you mount the drive using the bottom holes, ensure  
that you do not physically distort the drive by attempting to mount it on a stiff, non-flat surface.  
The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define  
the allowable mounting surface stiffness:  
K x X = F < 15lb = 67N  
where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion  
(units in inches or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of  
the four mounting points fixed and evaluating the out-of-plane deflection of the fourth mounting point when a  
known force (F) is applied to the fourth point.  
Note. Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Technology that the  
drive can meet the shock and vibration specifications given herein while mounted in such an adapter frame.  
Adapter frames that are available may not have a mechanical structure capable of mounting the drive so that it  
can meet the shock and vibration specifications listed in this manual.

9.5  
Grounding  
Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the  
user. The equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electri-  
cally isolating shock mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA  
ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of mount-  
ing the drive in the host equipment.  
Increased radiated emissions may result if you do not provide the maximum surface area ground connection  
between system ground and drive ground. This is the system designer’s and integrator’s responsibility.

Dual port support  
Savvio 10K.5 FC drives have two independent FC-AL ports. These ports may be connected on independent  
loops or on the same loop. Port A and Port B may be connected in any order or combination.  
• If both ports are connected on independent loops and hard addressing is used, the drive interface address is  
selected through the interface connector, both ports will seek the same loop address. If no conflict, both  
ports will have the same loop address.  
• If both ports are connected in the same loop and hard addressing is used, at least one port will attempt tak-  
ing a soft address to prevent an address conflict.  
Subject to buffer availability, the Savvio 10K.5 FC drives support:  
• Concurrent port transfers—The drive supports receiving transfers on both ports at the same time when the  
ports are on independent loops.  
• Full duplex—The drive supports sending FCP_Data, FCP_RSP, FCP_XFR_RDY and ELS transfers while  
receiving frames on both ports.

10.3.2  
Mode Sense data  
The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The  
drive maintains four sets of mode parameters:  
1. Default values  
Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the  
drive’s PCB. These default values can be changed only by downloading a complete set of new firmware  
into the flash E-PROM. An initiator can request and receive from the drive a list of default values and use  
those in a Mode Select command to set up new current and saved values, where the values are change-  
able.  
2. Saved values  
Saved values are stored on the drive’s media using a Mode Select command. Only parameter values that  
are allowed to be changed can be changed by this method. Parameters in the saved values list that are not  
changeable by the Mode Select command get their values from default values storage.  
When power is applied to the drive, it takes saved values from the media and stores them as current val-  
ues in volatile memory. It is not possible to change the current values (or the saved values) with a Mode  
Select command before the drive achieves operating speed and is “ready.” An attempt to do so results in a  
“Check Condition” status.  
Savvio 10K.5 FC Product Manual, Rev. D  
61  
       
On drives requiring unique saved values, the required unique saved values are stored into the saved val-  
ues storage location on the media prior to shipping the drive. Some drives may have unique firmware with  
unique default values also.  
On standard OEM drives, the saved values are taken from the default values list and stored into the saved  
values storage location on the media prior to shipping.  
3. Current values  
Current values are volatile values being used by the drive to control its operation. A Mode Select command  
can be used to change the values identified as changeable values. Originally, current values are installed  
from saved or default values after a power on reset, hard reset, or Bus Device Reset message.  
4. Changeable values  
Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values  
and saved values can be changed by a Mode Select command. A one (1) indicates the value can be  
changed. A zero (0) indicates the value is not changeable. For example, in Table 20, refer to Mode page  
81, in the row entitled “CHG.” These are hex numbers representing the changeable values for Mode page  
81. Note in columns 5 and 6 (bytes 04 and 05), there is 00h which indicates that in bytes 04 and 05 none of  
the bits are changeable. Note also that bytes 06, 07, 09, 10, and 11 are not changeable, because those  
fields are all zeros. In byte 02, hex value FF equates to the binary pattern 11111111. If there is a zero in any  
bit position in the field, it means that bit is not changeable. Since all of the bits in byte 02 are ones, all of  
these bits are changeable.  
The changeable values list can only be changed by downloading new firmware into the flash E-PROM.  
Note. Because there are often several different versions of drive control firmware in the total population of drives in the  
field, the Mode Sense values given in the following tables may not exactly match those of some drives.  
The following tables list the values of the data bytes returned by the drive in response to the Mode Sense com-  
mand pages for SCSI implementation (see the Fibre Channel Interface Manual).  
Definitions:  
DEF = Default value. Standard OEM drives are shipped configured this way.  
CHG = Changeable bits; indicates if default value is changeable.

Physical characteristics  
This section defines physical interface connector.  
10.5.1.1  
Physical description  
FIbre Channel drives may be connected in a loop together or with other compatible FC-AL devices. A maxi-  
mum of 127 devices may have addresses; however, one of the addresses is reserved for a fabric port switch  
device. This means 126 addresses are available for FC-AL devices. More FC-AL compatible devices may  
physically reside on the loop, but they will not be functional because they would not be able to obtain valid  
addresses.  
Port bypass circuits (PBCs) allow devices to be inserted into unpopulated locations or removed from the loop  
with loop operation recovery after a brief interruption. These PBCs are located external to the FC-AL device.  
Figure 13 shows the relationship between the PBC and FC-AL device.

*Short pins in mating backpanel connector.  
[1] This pin may be connected to external logic to detect the presence of the drive. The drive connects this  
pin to the common ground.  
[2] Pins 9, 10, 17, 18, and 39 are option select pins and are tied high by the drive circuitry. The preferred elec-  
trical connection at the backplane is either open or grounded (open for the ‘1’ setting, grounded for the ‘0’  
setting). Alternatively, these pins may be driven by a 3.3V logic device, pulled up to 3.3V through a pull-up  
resistor (recommended size of 10K ohm), or grounded through some other means.

10.5.6  
Power  
Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the  
drive connector are the same length.  
Four 12 volt pins provide +12 volt power to the drive. The current return for the +12 volt power supply is  
through the common ground pins. The supply current and return current must be distributed as evenly as pos-  
sible among the pins. The maximum current typically occurs while the drive motor is starting.  
Three 5 volt pins provide logic power to the drive. The current return for the +5 volt power supply is through the  
common ground pins. Distribute supply and return current as evenly as possible among the voltage and  
ground pins.  
The mating connector pins use shorter contacts to achieve power surge reductions and to aid in “hot plugging”  
the drives. There are longer voltage contacts in the connector to enable the drive filter capacitors to charge.  
Current to the drive through the long charge pins is limited by the system in which the drive operates. Three of  
the +12 volt pins are shorter to allow capacitive pre-charging through the longer +12 volt charge pin. Two of the  
+5 volt pins are shorter to allow capacitive precharging through the longer +5 volt charge pin.  
10.5.7  
Fault LED Out  
The Fault LED Out signal is driven by the drive when:  
• the drive detects failure of both ports  
• the drive detects an internal failure  
• the drive receives the appropriate fault LED command from the host  
The Fault LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper  
+5 volt supply through an appropriate current-limiting resistor. The LED and the current-limiting resistor are  
external to the drive.

proper +5 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor  
are external to the drive.  
10.5.9  
Enable port bypass signals  
The – Enable Bypass Port A (– EN BYP Port A) and – Enable Bypass Port B (– EN BYP Port B) signals control  
the port bypass circuits (PBC) located external to the disk drive. The PBC allows a loop to remain functional in  
the event of a drive failure or removal. When these signals are active, low, the PBC bypasses the drive on the  
associated port. When an Enable Bypass signal is active, the corresponding Port Bypass LED signal in con-  
nector J1 is driven low by the disk drive. A pull down resistor, 1K, located with the PBC should be used to  
insure the bypass is enabled if the disk drive is not installed.  
Failure modes detected by the disk drive that will enable bypass include:  
• Transmitter/receiver wrap test failure  
• Loss of receive clock  
• Loss of transmission clock  
• Drive interface hardware error  
10.5.10  
Motor start controls  
The drive’s motor is started according to the Start_1 and Start_2 signals described in Table 27. The state of  
these signals can be wired into the backplane socket or driven by logic on the backplane.

SEL_6 through SEL_0 ID lines  
The SEL_6 through SEL_0 ID lines determine drive address, and, optionally, for an Enclosure Services Inter-  
face. When the Parallel ESI line is high, the enclosure backpanel must provide address information on the SEL  
line. Refer to table 28 for a mapping of SEL to FC-AL physical addresses (AL_PA). You can think of the SEL  
lines as the equivalent of a backpanel logic plug. The drives does not provide pull up resistors on these lines.  
The backpanel is required to provide high and low inputs to the SEL_ID lines per the specifications in table 30  
on page 75.  
Note. Table 28 gives AL_PA values for each SEL value. The first entry in the table is SEL_ID 00. The last entry is SEL_ID  
7D. SEL_ID 7E is AL_PA 00 which is not valid for an NL_Port, so is not included in the table. Also, SEL_ID 7Fh  
does map to a valid AL_PA; however, this value signals the drive that physical addresses are not being assigned  
using the SEL lines and that a “soft” address will be determined by FC-AL loop initialization.  
When the Parallel ESI line is low, the enclosure backpanel logic switches to ESI mode if supported. There are  
two modes of ESI, seven bits of enclosure status and a bidirectional mode. ESI support and the mode are  
determined by the drive using a discovery process. Refer to the Fibre Channel Interface Manual for a descrip-  
tion of ESI operation.  
10.5.11.1 Parallel Enclosure Services Interface (ESI)  
The parallel ESI line is an output from the drive. This line provides the enclosure with an indication of the pres-  
ent function of the SEL lines. A high level, the default state, indicates the drive requires address information on  
the SEL lines. A low level indicates the drive is attempting an ESI transfer. The enclosure may not support ESI  
on any or all drive locations. It may only support the address function. Support of ESI is discovered by the  
drive. Refer to the Fibre Channel Interface Manual for a description of ESI operations.

Device control codes  
The drive inputs a Device Control Code on the DEV_CTRL_CODE lines at power up to determine the link rate  
on the Fibre Channel ports. Both ports run at the same rate. If the backpanel does not connect to these lines,  
the drive has 10K ohm pull up resistors that default the device control code to 7 (1.0625 GHz). Table lists the  
supported codes.

The serial output signal voltage characteristics are provided in Table 32. The outputs are not AC coupled in  
order to deliver maximum signal without rise and fall time degradation. You must AC couple the receiver to iso-  
late potentially different DC characteristics of the outputs and the receiver.
