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 temperature regulation. In particular, the drives must be securely mounted to guarantee the specified  
2.1  
STANDARDS  
The Pulsar.2 family complies with Seagate standards as noted in the appropriate sections of this manual and the Seagate SAS Interface  
Manual, part number 100293071.  
The drives are recognized in accordance with UL 60950 and CSA 60950 as tested by UL(CSA) and EN60950 as tested by TUV.

2.1.1  
Electromagnetic compatibility  
The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to use. 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 Communications.  
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.  
2.1.1.1  
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 10 through 12, DC  
power requirements.

GENERAL DESCRIPTION  
Pulsar.2 drives provide high performance, high capacity data storage for a variety of systems with a Serial Attached SCSI (SAS) interface.  
The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and  
high-density storage requirements.  
Pulsar.2 drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI  
specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface  
characteristics of this drive. Pulsar.2 drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the  
ANSI SCSI-1 standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the  
choice of populating their systems with either SAS or SATA drives. This allows users to continue to leverage existing investment in SCSI  
while gaining a 6Gb/s serial data transfer rate.  
The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data at Rest” based on the  
standards defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).  
Note. Never disassemble and do not attempt to service items in the enclosure. The drive does not contain user-replaceable parts.  
Opening for any reason voids the drive warranty.

3.5  
FORMATTED CAPACITIES  
Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be a multiple of 4 bytes.  
Users having the necessary equipment may modify the data block size before issuing a FORMAT UNIT 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:  
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We  
recommend customers use this capacity in 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 shown below. The Capacity stated is identical  
when the drive is formatted with or without PI enabled.

PROGRAMMABLE DRIVE CAPACITY  
Using the MODE SELECT command, the drive can change its capacity to something less than maximum. See the MODE SELECT (6)  
parameter list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that the  
drive will not change the capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs  
in the Number of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum  
number of LBAs is rounded down to the maximum capacity.  
3.7  
FACTORY-INSTALLED OPTIONS  
OEMs 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 LBA 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.  
3.8  
THIN PROVISIONING  
3.8.1  
Logical Block Provisioning  
The drive is designed with a feature called Thin Provisioning. Thin Provisioning is a technique which does not require Logical Blocks to be  
associated to Physical Blocks on the storage medium until such a time as needed. The use of Thin Provisioning is a major factor in SSD  
products because it reduces the amount of wear leveling and garbage collection that must be performed. The result is an increase in the  
products endurance. For more details on Logical Block Provisioning and Thin Provisioning, Reference the SBC-3 document provided by  
the T-10 committee.  
3.8.2  
Thin Provisioning capabilities  
The level of Thin Provisioning support may vary by product model. Devices that support Thin Provisioning are allowed to return a default  
data pattern for read requests made to Logical Blocks that have not been mapped to Physical Blocks by a previous WRITE command.  
In order to determine if Thin Provisioning is supported and what features of it are implemented requires the system to send a READ  
CAPACITY 16 (9Eh) command to the drive. Thin Provisioning and the READ CAPACITY 16 (9Eh) command is defined in the Seagate  
SCSI Command Reference 100293068..

SED  
A logical block provisioning management enabled (LBPME) bit set to one indicates that the logical unit implements logical block  
provisioning management. An LBPME bit set to zero indicates that the logical unit is fully provisioned and does not implement logical block  
provisioning management.  
A logical block provisioning read zeros (LBPRZ) bit set to one indicates that, for an unmapped LBA specified by a read operation, the  
device server sends user data with all bits set to zero to the data-in buffer. An LBPRZ bit set to zero indicates that, for an unmapped LBA  
specified by a read operation, the device server may send user data with all bits set to any value to the data-in buffer.  
PULSAR.2 SAS PRODUCT MANUAL, REV. C

3.8.3  
UNMAP  
The UNMAP command requests that the device server break the association of a specific Logical Block address from a Physical Block,  
thereby freeing up the Physical Block from use and no longer requiring it to contain user data. An unmapped block will respond to a READ  
command with data that is determined by the setting of the LBPRZ bit in the READ CAPACITY parameter data.  
3.8.4  
FORMAT UNIT command  
A device which supports Thin Provisioning will be capable of performing a SCSI FORMAT UNIT command which allocates Logical Blocks  
Addresses that are not linked to Physical Block Locations. A FORMAT command will cause all LBAs to become unmapped.  
3.8.5  
Protection Information (PI) and Security (SED)  
The requirements in this section apply to any device which supports LBA unmapping.  
In SCSI devices, umapped LBAs are defined as part of the Thin Provisioning model. Support of the Thin Provisioning model is indicated by  
the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data.  
When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs.  
If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be  
identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The  
drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data.  
If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI), the drive shall return  
scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access command CDB, this may result in the  
drive returning a standard PI error to the host.  
If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any LBA within the  
inaccessible region of the device.  
Additionally, an UNMAP command is not permitted on a locked band.

Sustained performance is defined as the worst case performance that the product will be able to achieve when the product is  
preconditioned as mentioned and host commands are aligned on 4KB boundaries. For models that support Lifetime Endurance  
Management, write values also take into account the worst case performance throttling that may occur to ensure the product meets  
specified reliability specifications.  
Due to the nature of Flash memory technologies there are many factors that can result in values different than those stated in this  
specification. Some discrepancies can be caused by bandwidth limitations in the host adapter, operating system, or driver limitations. It is  
not the intent of this manual to cover all possible causes of performance discrepancies.  
When evaluating performance of SSD devices, it is recommended to measure performance of the device in a method that resembles the  
targeted application using real world data and workloads. Test time should also be adequately large to ensure that sustainable metrics and  
measures are obtained.  
4.3  
START/STOP TIME  
The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.  
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT command with  
the START bit equal to 0, the drive becomes ready for normal operations within 15 seconds (excluding the error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP)  
primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT command  
with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP)  
primitive through either port, the drive becomes ready for normal operations within 15 seconds (excluding the error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a NOTIFY  
(ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.  
The START STOP UNIT command may be used to command the drive to stop. Stop time is 3 seconds (maximum) from removal of DC  
power. SCSI stop time is 3 seconds. There is no power control switch on the drive.  
4.4  
CACHE CONTROL  
All default cache mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Table 20 and 21.  
4.4.1  
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 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 generated.  
Data that has not been written to the medium is protected by a back up power source which provides the ability of the data to be written to  
non-volatile medium in the event of an unexpected power loss.  
The SYNCHRONIZE CACHE command may be used to force the drive to write all cached write data to the medium. Upon completion of a

1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.  
2. As NAND Flash devices age with use, the capability of the media to retain a programmed value begins to deteriorate.  
This deterioration is affected by the number of times a particular memory cell is programmed and subsequently erased.  
When a device is new, it has a powered off data retention capability of up to several years. With use the retention ca-  
pability of the device is reduced. Temperature also has an effect on how long a Flash component can retain its pro-  
grammed value with power removed. At high temperature the retention capabilities of the device are reduced. Data  
retention is not an issue with power applied to the SSD. The SSD drive contains firmware and hardware features that  
can monitor and refresh memory cells when power is applied.  
3. Endurance rating is the expected amount of host data that can be written by product when subjected to a specified work-  
load at a specified operating and storage temperature. For the specific workload to achieve this level of endurance,  
please reference JEDEC Specification JESD218. TBW is defined as 1x10^12 Bytes.  
5.1  
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 paragraph 6.3, "DC power requirements."  
• 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.  
5.1.1  
Unrecoverable Errors  
An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to read or write  
problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an unrecoverable data error  
is detected, a MEDIUM ERROR (03h) in the Sense Key will be reported. Multiple unrecoverable data errors resulting from the same cause  
are treated as 1 error.  
5.1.2  
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.

5.2  
ENDURANCE MANAGEMENT  
Customer satisfaction with Solid State Drives can be directly related to the internal algorithms which an SSD uses to manage the limited  
number of Program-Erase (PE) cycles that NAND Flash can withstand. These algorithms consist of Wearleveling, Garbage Collection,  
Write Amplification, Unmap, Data Retention, Lifetime Endurance Management.  
5.2.1  
Wear Leveling  
Wear Leveling is a technique used by the drive to ensure that all Flash cells are written to or exercised as evenly as possible to avoid any  
hot spots where some cells are used up faster than other locations. Wear Leveling is automatically managed by the drive and requires no  
user interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable product operation.  
5.2.2  
Garbage Collection  
Garbage Collection is a technique used by the drive to consolidate valid user data into a common cell range freeing up unused or obsolete  
locations to be erased and used for future storage needs. Garbage Collection is automatically managed by the drive and requires no user  
interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable product operation.  
5.2.3  
Write Amplification  
While Write Amplification is not an algorithm, it is a major characteristic of SSD's that must be accounted for by all the algorithms that the  
SSD implements. The Write Amplification Factor of an SSD is defined as the ratio of Host/User data requested to be written to the actual  
amount of data written by the SSD internal to account for the user data and the housekeeping activities such as Wear Leveling and  
Garbage Collection. The Write Amplification Factor of an SSD can also be directly affected by the characteristics of the host data being  
sent to the SSD to write. The best Write Amplification Factor is achieved for data that is written in sequential LBA's that are aligned on 4KB  
boundaries. The worst case Write Amplification Factor typically occurs for randomly written LBA's of transfer sizes that are less than 4KB  
and that originate on LBA's that are not on 4KB boundaries.  
5.2.4  
UNMAP  
A new SCSI command has been added to the SSD as part of the Thin Provisioning feature set. Use of the UNMAP command reduces the  
Write Amplification Factor of the drive during housekeeping tasks such as Wear Leveling and Garbage Collection. This is accomplished  
because the drive does not need to retain data which has been classified by the host as obsolete.  
5.2.5  
Data Retention  
Data Retention is another major characteristic of SSD's that must be accounted for by all the algorithms that the SSD implements. While  
powered up, the Data Retention of SSD cells are monitored and rewritten if the cell levels decay to an unexpected level. Data Retention  
when the drive is powered off is affected by Program and Erase (PE) cycles and the temperature of the drive when stored.  
5.2.6  
Lifetime Endurance Management (Available on select models)  
write workload could be such that the drive experiences a high Write Amplification Factor that could lead to potential wear out prior to the  
drive achieving it's expected field life. Additionally, the Data Retention spec of the SSD needs to be considered to ensure the spec is met  
once the drive is worn out. Seagate has implemented a Lifetime Endurance Management technique which helps OEMS and user to avoid  
early wear out. By monitoring the write workload being sent to the drive, the drive can add additional response time to WRITE commands  
to provide a sustainable level of performance that is capable of being sustained for the life of the drive. Most users may never see this  
added response time in their applications.  
5.2.7  
SSD Percentage Used Endurance Indicator  
An application can interrogate the drive through the host to determine an estimate of the percentage of device life that has been used. To  
accomplish this, issue a LOG SENSE command to log page 0x11. This allows applications to read the contents of the Percentage Used  
Endurance Indicator parameter code. The Percentage Used Endurance Indicator is defined in the T10 document SBC-3 available from the  
T10 committee.  
PULSAR.2 SAS PRODUCT MANUAL, REV. C

5.3  
RELIABILITY AND SERVICE  
Integrators can enhance the reliability of Pulsar.2 drives by ensuring that the drive receives adequate cooling. Section 6.0 provides  
temperature measurements and other information that may be used to enhance the service life of the drive. Section 10.2 provides  
recommended air-flow information.  
5.3.1  
Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)  
The production drive shall achieve an AFR of 0.44% (MTBF of 2,000,000 hours) when operated in an environment that ensures the case  
may increase the product AFR (decrease the MTBF). The AFR (MTBF) is a population statistic not relevant to individual units.  
The AFR (MTBF) specification is based on the following assumptions for Enterprise Storage System environments:  
• 8760 power-on hours per year.  
• 250 average on/off cycles per year.  
• Operations at nominal voltages.  
the specifications in Section 6.5 will increase the product AFR and decrease the MTBF.  
5.3.2  
Preventive maintenance  
No routine scheduled preventive maintenance is required.  
5.3.3  
Hot plugging the drive  
When a drive is powered on by switching the power or hot plugged, the drive runs a self test before attempting to communicate on its’  
interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB. An attached device should  
respond to the link reset. If the link reset attempt fails, or any time the drive looses sync, the drive initiated link reset. The drive will initiate  
link reset once per second but alternates between port A and B. Therefore each port will attempt a link reset once per 2 seconds assuming  
both ports are out of sync.  
If the self-test fails, the drive does not respond to link reset on the failing port.  
Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard, or ESD potential hazard  
is presented during the hot connect/disconnect operation. Discharge the static electricity from the drive carrier prior to insert-  
ing it into the system.  
5.3.4  
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 administrators 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 failures.  
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance 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 DEXCPT 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.  
An application 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.  
An application can interrogate the drive through the host to determine the time remaining before the next scheduled measurement and  
data logging process occurs. To accomplish this, issue a LOG SENSE command to log page 0x3E. This allows applications to control  
when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the REZERO UNIT command resets the timer.  
PULSAR.2 SAS PRODUCT MANUAL, REV. C

Performance impact  
S.M.A.R.T. attribute data is saved to the media so that the events that caused a predictive failure can be recreated. The drive measures  
and saves parameters once every hour subject to an idle period on the drive interfaces. The process of measuring off-line attribute data  
and saving data to the media is interruptible. The maximum on-line only processing delay is summarized below  
Maximum processing delay  
Fully-enabled delay  
DEXCPT = 0  
S.M.A.R.T. delay times  
75 ms  
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 appropriate 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 interval 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 firmware keeps a running count  
of the number of times the error rate for each attribute is unacceptable. To accomplish 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 predictive 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.  
5.3.5  
Thermal monitor  
Pulsar.2 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. (i.e., the reference temperature 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 temperature 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 specified limit in compliance with  
the SCSI standard. The drive temperature is reported in the FRU code field of MODE SENSE data. Administrators 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 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 8) can be used to set this trip point. The default value for this drive is listed in the table, however,  
applications can set it to any value in the range defined. If a temperature is specified that is greater than the maximum allowed in this field,  
the temperature is rounded down to the maximum allowed. A sense code is sent to the host to indicate the rounding of the parameter field.

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 contents, but does some fundamental tests  
and scans portions of the media.  
If DST encounters an error during either of these tests, it reports a "diagnostic failed" condition. If the drive fails the test, remove it from  
service and return it to Seagate for service.  
5.3.6.1  
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 drive parameters are not modified to test the drive more stringently, and the recovery capabilities 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 recovery processes required to recover the data.  
The following conditions are considered DST failure conditions:  
• Read error after recovery attempts are exhausted  
• Write error after recovery attempts are exhausted  
Recovered errors will not be reported as diagnostic failures.  
5.3.6.2  
Implementation  
This section provides all of the information necessary to implement the DST function on this drive.  
5.3.6.2.1  
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 UNIT, or another  
DST. It is the responsibility of the host application to determine the “not ready” cause.  
5.3.6.2.2  
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.  
5.3.6.2.3  
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 two segments: an electrical 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 contents, 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 "diagnostic failed" condition. This option provides a quick confidence test of the drive.  
PULSAR.2 SAS PRODUCT MANUAL, REV. C  
17  
 
Extended test (Function Code: 010b)  
The objective of the extended test option is to empirically test critical drive components. The read operation tests the media contents. The  
integrity of the media is checked through a read/verify scan of the media.  
The anticipated length of the Extended test is reported through the Control Mode page.  
5.3.6.2.4  
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 parameter 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.  
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.  
5.3.6.2.5  
Abort  
There are several ways to abort a diagnostic. Applications can use a SCSI Bus Reset or a Bus Device Reset message to abort the  
diagnostic.  
Applications 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).  
5.3.7  
Product warranty  
Warranty terms will vary based on type of warranty chosen: “Managed Life” or “Usage Based”. Consult your Seagate sales representative  
for warranty terms and conditions.  
Managed Life Warranty  
This warranty is term based and includes the Lifetime Endurance Management feature stated in section 6.2.6.  
Usage Based Warranty  
This warranty is based on the shorter of term and endurance usage of the drive.  
Shipping  
When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate 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 transit. 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, atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

Startup power is measured from the time of power-on to the time that the drive reaches operating condition and can process media  
access commands.  
• Peak operating mode  
During peak operating mode, the drive is tested in various read and write access patterns to simulate the worst-case power consump-  
tion.  
• Idle mode power  
Idle mode power is measured with the drive powered up and ready for media access commands, with no media access commands  
having been received from the host.

For +12 V, a –10% tolerance is allowed during initial start but must return to ±5% before reaching ready state. 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 1.7% 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 start, are measured after a 10-minute warm up.

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.

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  
6.5.4.1  
Shock  
a. Operating—normal  
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:  
1000 Gs at a maximum duration of 0.5ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.  
Note. This specification does not cover connection issues that may result from testing at this level.  
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.

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.

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 corrosive chemicals as electronic  
drive component reliability can be affected by the installation environment. The silver, 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 vulcanized 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.

7.0 ABOUT FIPS  
The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard used to  
accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS PUB 140-2)' and is issued by the  
National Institute of Standards and Technology (NIST).  
Purpose  
This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security system  
protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security: Level 1, Level 2,  
Level 3 and Level 4. These levels are intended to cover the wide range of potential applications and environments in which cryptographic  
modules may be employed.  
Validation Program  
Products that claim conformance to this standard are validated by the Cryptographic Module Validation Program (CMVP) which is a joint  
effort between National Institute of Standards and Technology (NIST) and the Communications Security Establishment (CSE) of the  
Government of Canada. Products validated as conforming to FIPS 140-2 are accepted by the Federal agencies of both countries for the  
protection of sensitive information (United States) or Designated Information (Canada).  
In the CMVP, vendors of cryptographic modules use independent, accredited testing laborites to have their modules tested. National  
Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratories perform cryptographic module compliance/conformance  
testing.  
Seagate Enterprise SED  
to satisfy FIPS 140-2 Level 2 requirements. In order to operate in FIPS Approved Mode of Operation, these SEDs require security  
initialization. For more information, refer to 'Security Rules' section in the 'Security Policy' document uploaded on the NIST website. To  
Security Level 2  
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the requirement for  
tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the module. Tamper-evident coat-  
ings or seals are placed on a cryptographic module so that the coating or seal must be broken to attain physical access to the critical  
security parameters (CSP) within the module. Tamper-evident seals (example shown in Figure 14, page 34) are placed on covers to  
protect against unauthorized physical access. In addition Security Level 2 requires, at a minimum, role-based authentication in which a  
cryptographic module authenticates the authorization of an operator to assume a specific role and perform a corresponding set of ser-  
vices.

ABOUT SELF-ENCRYPTING DRIVES  
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as “protection of  
data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as detailed in Section  
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital  
communications industry. Seagate’s SED models comply with the standards published by the TCG.  
To use the security features in the drive, the host must be capable of constructing and issuing the following two SCSI commands:  
• SECURITY PROTOCOL OUT  
• SECURITY PROTOCOL IN  
These commands are used to convey the TCG protocol to and from the drive in the appropriate command payloads.  
8.1  
DATA ENCRYPTION  
Encrypting drives use one in-line encryption engine for each port, employing AES-256 data encryption in Cipher Block Chaining (CBC)  
mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engines are  
always in operation and cannot be disabled.  
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the drive, and is inaccessible to  
the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile temporary storage (DRAM) external to  
8.2  
CONTROLLED ACCESS  
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the drive security  
services. Security-related commands will not be accepted unless they also supply the correct credentials to prove the requester is  
authorized to perform the command.  
8.2.1  
Admin SP  
available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.  
8.2.2  
Locking SP  
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using  
the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band has its  
own password called BandMasterX where X is the number of the data band (0 through 15).  
8.2.3  
Default password  
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only be read by the  
host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the default MSID password as the  
authority to change all other passwords to unique owner-specified values.  
8.3  
RANDOM NUMBER GENERATOR (RNG)  
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random numbers to the  
host for system use, including using these numbers as Authentication Keys (passwords) for the drive’s Admin and Locking SPs.  
8.4  
DRIVE LOCKING  
bands.  
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In addition  
"ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands "LockOnReset" setting of  
"PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This scenario occurs if the drive is removed from its  
cabinet. The drive will not honor any data READ or WRITE requests until the bands have been unlocked. This prevents the user data from  
being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system.  
When the drive is shipped from the factory, the firmware download port is unlocked allowing the drive to accept any attempt to download  
new firmware. The drive owner must use the SID credential to lock the firmware download port before firmware updates will be rejected.

8.5  
DATA BANDS  
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band) which  
comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range. The real estate for this  
band is taken from the Global Band. An additional 14 Data Bands may be defined in a similar way (Band2 through Band15) but before  
these bands can be allocated LBA space, they must first be individually enabled using the EraseMaster password.  
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).  
Each data band has its own drive-generated encryption key and its own user-supplied password. The host may change the Encryption Key  
8.6  
CRYPTOGRAPHIC ERASE  
A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data  
encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one key and will be read  
using a different key. Since the drive overwrites the old key with the new one, and keeps no history of key changes, the user data can  
never be recovered. This is tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.  
8.7  
AUTHENTICATED FIRMWARE DOWNLOAD  
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files  
which have been cryptographically signed by the appropriate Seagate Design Center.  
Three conditions must be met before the drive will allow the download operation:  
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.  
2. The download file must be signed and authenticated.  
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the  
correct drive model, and have compatible revision and customer status.  
8.8  
POWER REQUIREMENTS  
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive  
controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and  
a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply. See the tables in  
8.9  
SUPPORTED COMMANDS  
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed  
in Table 16:  
• SECURITY PROTOCOL OUT (B5h)  
• SECURITY PROTOCOL IN (A2h)  
8.10  
SANITIZE - CRYPTOGRAPHIC ERASE  
This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with a new  
data encryption key randomly generated by the drive. Sanitize CRYPTOGRAPHIC ERASE is a SCSI CDB Op code 48h and selecting the  
service action code 3 (CRYPTOGRAPHIC ERASE).  
8.11  
REVERTSP  
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs (Security  
Providers) on the device to their original factory state. In order to execute the RevertSP method the unique PSID (Physical Secure ID)  
printed on the drive label must be provided. PSID is not electronically accessible and can only be manually read from the drive label or  
scanned in via the 2D barcode.  
8.12  
SANITIZE FEATURE SET ON SED DRIVES  
The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or modifications described in  
this section.  
The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT sub-commands.  
Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives shall support the  
command.

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 SAS system error considerations (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 9.4)  
• Auto-Reallocation (see Section 9.5)  
The read error rates and specified storage capacities are not dependent on host (initiator) defect management routines.  
9.1  
DRIVE INTERNAL DEFECTS/ERRORS  
During the initial drive manufacturing test 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). At factory format time, these known defects are also  
deallocated, that is, marked as retired 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 SAS Interface Manual. Also, more information on the drive Error  
Recovery philosophy is presented in the SAS Interface Manual.  
The drive uses a vendor unique format to report defects via the READ DEFECT DATA command pending T10 standardization of a format  
for Solid State Devices. This format defect type is defined as 110b in the SCSI FORMAT UNIT command. The definition of the 110b format  
is defined in the following table.

9.2  
DRIVE ERROR RECOVERY PROCEDURES  
When an error occurs during drive operation, the drive performs error recovery procedures to attempt to recover the data. The error  
recovery procedures used are not user changeable.  
9.3  
SAS SYSTEM ERRORS  
Information on the reporting of operational errors across the interface is given in the SAS Interface Manual. The SSP Response returns  
information to the host about numerous kinds of errors. 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 SAS 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.  
9.4  
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 reads across the entire addressable space 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  
and reallocated.  
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 activity.  
Since the background scan functions are only done during idle periods, BMS causes a negligible impact to system performance. The BMS  
scan is performed after 500ms of idle time. Other features that normally use idle time to function will function normally because BMS  
functions for bursts of 500ms 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.  
9.5  
AUTO-REALLOCATION  
Auto-Reallocation allows the drive to reallocate unreadable locations on a subsequent write command if the recovery process deems the  
location to be defective. The drive performs auto-reallocation on every WRITE command. With each write to a Logical LBA, the drive  
writes the data to a different physical media location. Physical locations that return unrecoverable errors are retired during future WRITE  
attempts and associated recovery process.  
This is in contrast to the system having to use the REASSIGN BLOCKS command to reassign a location that was unreadable and then  
generate a WRITE command to rewrite the data. This operation requires that AWRE and ARRE are enabled—this is the default setting  
from the Seagate factory.

9.6  
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 formatted drives are physically  
formatted to 520 byte LBA’s 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 managed 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.  
9.6.1  
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 WRTPROTECT 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 Protection Information are  
transmitted at LBA boundaries across the interface if RDPROTECT and WRTPROTECT 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 of  
Protection Information (e.g. 0xFFFFFFFF) to be stored on the media, but the 8 bytes will not be transferred to the host during a READ  
command.  
Type 3 - Seagate products do not support Type 3.  
9.6.2  
Setting and determining the current Type Level  
A drive is initialized to a type of PI by using the FORMAT UNIT command on a PI capable drive. Once a drive is formatted 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. A drive can only be formatted  
to a single PI Type. It can be changed at anytime to a new Type but requires a FORMAT UNIT command 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 UNIT CDB command: 04 90 00 00 00 00, parameter data: 00 A0 00 00  
Type 2 PI FORMAT UNIT CDB command: 04 D0 00 00 00 00, parameter data: 00 A0 00 00  
9.6.3  
Identifying a Protection Information drive  
The Standard INQUIRY data 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.  
Note. For further details with respect to PI, please refer to SCSI Block Commands - 3 (SBC-3) Draft Standard documentation.

10.0 INSTALLATION  
Pulsar.2 drive installation is a plug-and-play process. There are no jumpers on the drive.  
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate the  
drive. In such systems, the host system typically provides a carrier or tray into which the drive must be mounted. Mount the drive to the  
carrier or tray provided by the host system using four M3 x 0.5 metric screws. When tightening the screws, use a maximum torque of 4.5  
in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws. The drive can be mounted in any orientation.  
Note. SAS drives are designed to be attached to the host system without I/O or power cables. If the intent is to use the drive in a  
non-backplane host system, connecting the drive using high-quality cables is acceptable as long as the I/O cable length does  
not exceed 10 meters (32.8 feet).  
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host system. This connects the  
drive directly to the system’s SAS connector. The SAS connector is normally located on a SAS backpanel. See Section 11.4.1 for  
additional information about these connectors.  
Power is supplied through the SAS connector.  
The drive is shipped from the factory low-level formatted in 512-byte logical blocks. Reformatting the drive is only required if the application  
requires a different logical block size.

DRIVE ORIENTATION  
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in  
horizontal (level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.  
10.2  
COOLING  
Cabinet cooling must be designed by the customer so that the temperature of the drive will not exceed temperature conditions specified in  
The rack, cabinet, or drawer environment for the drive must provide heat removal from the assembly. The system designer should confirm  
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 6.5.1 in which case the drive  
should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air flow. Also, the shortest  
possible path between the air inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources  
within the rack, cabinet, or drawer environment.

10.3 DRIVE MOUNTING  
Mount the drive using the bottom or side mounting holes. If mounting 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.  
10.4  
GROUNDING  
Signal ground (PCBA) and case 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 drive with no electrically isolating shock mounts. If it is desired for the system chassis to  
not be connected to the drive ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of  
mounting the drive in the host equipment.  
Increased radiated emissions may result if designers 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  
Pulsar.2 SAS drives have two independent ports. These ports may be connected in the same or different SCSI domains. Each drive port  
has a unique SAS address.  
The two ports have the capability of independent port clocking (e.g. both ports can run at 6Gb/s or the first port can run at 6Gb/s while the  
second port runs at 3Gb/s.) The supported link rates are 1.5, 3.0, or 6.0 Gb/s.  
Subject to buffer availability, the Pulsar.2 drives support:  
• Concurrent port transfers—The drive supports receiving COMMAND, TASK management transfers on both ports at the same time.  
• Full duplex—The drive supports sending XFER_RDY, DATA and RESPONSE transfers while receiving frames on both ports.

11.3.2 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 changeable.  
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 com-  
mand 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 values in volatile memory. It is not  
possible to change the current values (or the saved values) with a MODE SELECT command before the drive is “ready.” An attempt to  
do so results in a “Check Condition” status.  
On drives requiring unique saved values, the required unique saved values are stored into the saved values 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 change-  
able. For example, in Table 19, 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.  
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 command pages for SCSI  
implementation (see the SAS Interface Manual).  
DEF = Default value. Standard OEM drives are shipped configured this way.  
CHG = Changeable bits; indicates if default value is changeable.

11.4.7 Power  
The drive receives power (+5 volts and +12 volts) through the SAS device connector.  
Three +12 volt pins provide power to the drive, 2 short and 1 long. 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 possible among the pins.  
Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through the common  
ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot plugging.

The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt supply through  
an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See Table 26 for the output  
characteristics of the LED drive signals.

SAS-2 SPECIFICATION COMPLIANCE  
Seagate SAS-2 drives are entirely compatible with the latest SAS-2 Specification (T10/1760-D) Revision 16.  
The most important characteristic of the SAS-2 drive at 6Gb/s is that the receiver is capable of adapting the equalizer to optimize the  
receive margins. The SAS-2 drive has two types of equalizers:  
1. A Decision Feedback Equalizer (DFE) which utilizes the standard SAS-2 training pattern transmitted during the SNW-3 training gap.  
The DFE circuit can derive an optimal equalization characteristic to compensate for many of the receive losses in the system.  
2. A Feed Forward Equalizer (FFE) optimized to provide balanced receive margins over a range of channels bounded by the best and  
worst case channels as defined by the relevant ANSI standard.  
11.7  
ADDITIONAL INFORMATION  
Please contact your Seagate representative for SAS electrical details, if required.
