Chapter 1: Introduction
This Chapter introduces the 2Gb SANbloc Series. The main
features of the Series are described along with a list of the
models that are available.
Introduction
The 2Gb SANbloc Series provides a highly flexible, high
performance storage solution that evolves to meet your
changing needs. Based on a modular, “building block”
enclosure design, the 2Gb SANbloc Series offers exceptional
scalability. Each enclosure supports up to 14 disk drives, or
1TB of capacity in a dense 3U form factor. As your storage
needs grow, simply add 2Gb SANbloc enclosures dynami-
cally - up to a total of 8 enclosures. The 2Gb SANbloc
Series can be scaled in multiple dimensions, enabling
flexible configuration of capacity, performance and
functionality, to match and grow with virtually any appli-
cation or IT environment. The enclosure is available with
your choice of copper, or optical I/O modules, and is
downward compatible to 1GB, protecting your investment. A
high performance, industry first Quad Loop (4 FCAL loops
on one enclosure) capability provides over 700 MB/s from a
single enclosure. 2Gb Fibre Channel connectivity provides
simplified cabling and extremely high bandwidth, for
outstanding performance in demanding applications.
Features
• Redundant data paths with dual-ported fibre drives and dual
(200MB/s) fibre channel loops for a total of 400 MB/s.
• Quad Loop feature, provides over 700MB/s from a single
enclosure.
Introduction
20
• Downward compatible to 1GB.
• Dense enclosure with 14 drives in a 3U form factor.
• Scalable to 8.2TB (112 drives), support for 15K rpm drives.
• Enhanced enclosure services (SES) monitoring and reporting.
• No single point of failure, with redundant, hot-swappable
components.
• Intuitive, comprehensive management with Spheras Storage
Manager.
• User installable, configurable and on-line maintainable.
• Industry-standard 19-inch rackmount or deskside configuration.
• Dual AC power supplies.
Disk Drive Carrier
Power Supplies
The disk drive carrier supports one inch, SCA-2 direct attach
disk drives. The 2Gb SANbloc Series can hold up to
fourteen disk drive carriers. The disk drives can be hot
swapped and the disk drive carriers provide for blind mating.
The 2Gb SANbloc Series uses two AC power supplies for
normal operation, providing redundancy of the power
system. The power supplies can be hot swapped. The AC
power supplies provide 673 Watts continuous output power
and 853 Watts peak output power. The power supplies
provide active current sharing, power factor correction, over
current and over voltage protection is also provided. The
power supplies have individual power inputs.
CAUTION: Power supply cords shall have conductors with a
2
cross-sectional area not less than 4mm . This cross-sectional area
corresponds to a minimum 10AWG wire.
Features
21
Cooling System
Cooling is provided by the two Advanced Cooling Modules
(ACMs) located at the rear of the enclosure. Each of the
ACM units contain two variable speed fans. The enclosure
requires four fans for normal operation, but will operate
correctly with one fan failed (redundancy is lost if one fan is
failed in either ACM), however, it is recommended that the
failed fan be replaced as soon as possible. The ACM units
can be hot swapped. The LS Module monitors and controls
the speed of each fan. The speed is set depending on the
ambient temperature and failed status. The fans are set to
full speed if one fan is failed. The following table shows
how the fan speed relates to temperature change.

supply from the enclosure.
Safety Statements
30
Unpacking and Initial Setup
When you receive your system, visually inspect the exterior
of the packaging for any signs of damage. If any damage is
found the carrier and Adaptec should be informed immedi-
ately, and they will advise you of the appropriate action. The
cartons are sealed using packaging tape which should be cut
open in the normal manner. Exercise caution when lifting
out the components. At this point the contents should be
verified against the packing list and Adaptec should again
be notified if any discrepancies exist. Anti-static precautions
must be observed before removing any of the components.
Installing the System in an Equipment Rack
Before installing the 2Gb SANbloc Series in an equipment
rack, it is essential that the following guidelines are
complied with, to ensure the safe and efficient operation of
the system. The 2Gb SANbloc Series can be installed in
open or closed equipment racks, with a front width of 19”,
by observing the environmental, electrical, and mechanical
precautions described below.
Ambient
Temperature
Installation of the rack system in a standard 19” cabinet may
lead to a differential between the room ambient temperature
and the internal ambient temperature of the rack
environment. The operating temperature of the 2Gb
o
o
SANbloc Series is between 5 C to 40 C. However, it is not
recommended that the system be continuously run at these
extreme temperatures. Consideration should therefore be
given to ensure that the room ambient temperature is
compatible with these specifications.
Unpacking and Initial Setup
31
Air Flow
To ensure that the internal heat build up is properly dissi-
pated into the room environment, air flow should in no way
be restricted. It is essential that no air vents are blocked, and
that the system is a minimum of one meter from a solid
surface such as a wall or partition. Air flow through the 2Gb
SANbloc Series is from front to rear.
Mechanical Loading
Consideration should be given to the loading of any
equipment racks. To maintain a low centre of gravity (thus
reducing the likelihood of instability) racks should be loaded
(where possible) from the bottom of the equipment rack
upwards. This is recommended to ensure personal safety.
CAUTION: When installing or removing a rack mount enclosure,
remove all disk drives. It is recommended that you work with at
least one other person when installing an enclosure. This is neces-
sary to prevent personal injury and damage to the enclosure.
Installing the System in an Equipment Rack
32
Electrical Considerations
When installing the 2Gb SANbloc Series the following
electrical considerations must be applied.
Circuit Overloading
Care should be taken to ensure that the current does not
exceed the rating of the power source circuitry. This
includes cabling, power distribution units, filters and any
other devices through which the main current flows. The
electrical power rating of the enclosure is 100 - 240 VAC,
10 - 5 Amps (50/60 Hz), and this must be added to the power
demands of any other electrical devices installed in the
equipment rack to arrive at a total power consumption
figure. In addition, surge currents must be catered for. Disk
drives may consume twice the amount of current at start-up
time as they do during steady state operation.
Setting Fibre Channel Loop Speed (2Gb or 1Gb)
The 2Gb SANbloc Series can be operated with fibre channel
loop speeds of either 2Gb or 1Gb. The loop speed is set
through the use of a jumper (JP2) located on the LS Module.
Note: If the enclosure has dual LS modules the following
procedures must be applied to both LS modules.
2Gb Operation
To set the fibre channel loop speed to 2Gb operation:
1 Remove the LS Module from the front of the enclosure.
2 On the LS Module locate the jumper position JP2 (Figure 2-1).
3 Install a jumper at JP2.
4 Replace the LS module.
Electrical Considerations
33
1Gb Operation
To set the fibre channel loop speed to 1Gb operation:
1 Remove the LS module from the front of the enclosure.
2 On the LS Module locate the jumper position JP2 (Figure 2-1).
3 For 1Gb operation there should be no jumper installed at JP2. If
one is installed, remove it.
4 Replace the LS module.
Figure 2-1 Location of Jumpers on LS Module
Setting Fibre Channel Loop Speed (2Gb or 1Gb)
34
Split Fibre Channel Loop Operation (Quad Loop)
The 2Gb SANbloc Series LS module allows for split FC
Loop operation, with two dual fibre channel loops of seven
disk drives each. In this split loop mode the primary port (I/
O Slot A) will form a loop using the first seven drives, 1 to 7
(from right hand side of rackmount systems). The expansion
port (I/O Slot B) will form a second loop using the
remaining 7 drives, 8 to 14 (from right hand side of
rackmount systems).
Note: If the enclosure has dual LS modules the following
procedures must be applied to both LS modules.
CAUTION: Enclosures operating in split loop mode can not be
daisy chained to other enclosures.
Setting Up Split Loop
Operation
To operate the 2Gb SANbloc Series enclosure in split fibre
channel loop mode, follow this procedure:
1 Remove the LS module from the front of the enclosure.
2 On the LS Module locate the jumper position JP3 (Figure 2-1).
3 To operate in split loop mode, install a jumper at JP3.
4 Replace the LS module.
Removing Split Loop
Operation
To remove split fibre channel loop operation from the 2Gb
SANbloc Series enclosure, follow this procedure:
1 Remove the LS module from the enclosure and locate jumper
JP3 (Figure 2-1).
2 To remove split loop operation, remove jumper JP3.
3 Replace the LS module.

Configurations
This section describes the procedures for cabling the main
configurations of the 2Gb SANbloc Series JBOD.
Note: The following configuration procedures refer to
connecting the 2Gb SANbloc Series directly to the host
system. It is also possible to connect the system using a Hub/
Switch.
CAUTION: Before working on the enclosure, ensure that anti-
static precautions have been taken. The minimum requirement is
an anti-static wrist strap and grounding wire.

JBOD Configurations
There are two JBOD configurations covered in this Instal-
lation Guide:
• Dual FC Loop mode (including how to daisy chain enclosures)
• Quad Loop (single enclosure with 4 FCAL loops)
Note: The following examples show the Copper/Copper I/O
Module option for illustration purposes. The configuration
procedures are identical for all I/O Module options.
Dual FC Loop
Configuration
Note: For dual FC Loop enclosures there must be two LS
modules installed in the enclosure.
This section describes the procedure for connecting a dual
FC Loop configuration to your host computer, and how to
daisy chain these enclosures together.
To connect the dual FC Loop enclosure to the host:
Note: You will need two HBA’s in your host system, or a single
HBA with support for two connections. A hub, switch or two hosts
with HBA may also be used.
1 Insert the connector on the first cable, into the top connector on
the first I/O module (see Figure 3-2).
2 Insert the other end of this cable into the connector on your
HBA.
3 Insert the connector on the second cable, into the top connector
on the second I/O module (see Figure 3-2).
4 Insert the other end of this cable into the connector on your
HBA.

Quad Loop
Configuration
Note: Quad loop configuration requires that the enclosure be
configured in split loop mode. To set split loop mode, a jumper
must be installed at jumper location JP3 on each LS module
in the enclosure.
This section describes the procedure for connecting the
enclosure in quad loop mode. For this configuration there
must be two LS modules and two I/O modules installed in
the enclosure.
1 Remove both LS modules from the enclosure and install a
jumper, at jumper location JP3 if one is not already installed.
This sets the enclosure to operate in split loop mode.
2 Attach cables to the top and bottom connector of both I/O
modules (see Figure 3-4).
3 Attach the other end of these four cables to your host systems.

Connecting a Power Source
The 2Gb SANbloc enclosure supports dual AC power
supplies. Only one power supply is required for normal
operation. However, a second, optional power supply may be
added to provide a redundant power system. Each power
supply has its own AC power inlet.
CAUTION: Power supply cords shall have conductors with a
2
cross-sectional area not less than 4mm . This cross-sectional area
corresponds to a minimum 10AWG wire.

Disk Drive Spin Up Sequence
At power on, the LS module will perform its internal start up
initialization routine. Then the LS module will assert the
disk drive START_1 and START_2 motor start signals low
for disk drive slots 7 through 13, which will spin up the first
7 disk drives immediately. The LS module will then assert
the disk drive START_2 motor start signal low and leave the
START_1 motor start signal high for disk drive slots 0
through 6 which will command the second seven disk drives
to spin up after a delay of 12 seconds times the modulo 8
value of the numeric SEL_ID of the disk drive.
Once the enclosure is powered up and all 14 drives are spun
up as depicted above, the enclosure will support immediate
drive spin up with two power supplies present.
Modulo 8
The drive spin up sequence above uses modulo 8 to calculate
the spin up delay. Modulo 8 is determined by:
(SHELF ID x DRIVE NUMBER)/8 = NUMBER + REMAINDER
It is the REMAINDER value that is used for the calculation
as it is always between 0 and 7 (hence modulo 8). The drive
spin up time can then be calculated as follows:
REMAINDER x MODE PAGE SETTING = SPIN UP DELAY (Seconds)
EXAMPLE: A typical Mode Page Setting is 12, so if the
Remainder = 7, the Spin Up Delay would be 7 x 12, or 84
seconds.

Chapter 4: RAID Configurations
This chapter describes how to set up, configure and use the
2Gb SANbloc Series RAID Controller. Some general infor-
mation about the RAID controller is also provided.
2Gb SANbloc Series RAID Controller Introduction
The 2Gb SANbloc RAID Controller is a high performance
controller, providing two host fibre channel and two device
fibre channel interfaces. It is an intelligent, caching
controller that supports RAID levels 0, 1, 3, 5, 0+1,
and JBOD. The controller enables multiple hosts to
access an array of disk drives, which can be configured
as one or more virtual storage devices (logical units).
The controller provides continuous access to data in the
event of a disk drive failure. When configured in a dual-
active controller system, the RAID controller also provides
continuous access to data in the event of a controller failure.
This dual-active controller system is one in which two
controllers share access to the same array of disk drives.
In the event of a controller failure, controller opera-
tions are assumed by the surviving controller through
a failover process. The failed controller can then be
removed and replaced while the system is online. The
new controller resumes processing array operations in
a failback process. During failover and failback, write
cache coherency is maintained with the disk drives.
Three circuit boards make up the RAID Controller:
• Controller: The controller circuit board contains the main
controller and peripheral functions, including processor,
control-store memory, XOR engine and cache controller, and
2Gb SANbloc Series RAID Controller Introduction
48
host and device fibre channel input/output processors (IOPs).
• I/O: The I/O circuit board provides the interface to the disk
drive enclosure (device) and host as well as general support
functions. It also contains the switching power supply, which
generates +3.3 Vdc and +2.5 Vdc from +5 Vdc, hot-swap
circuits, and battery backup unit (BBU) circuits.
• Ethernet (optional): The ethernet circuit board provides an
ethernet interface to the controller, and connections for debug
and out-of-band service to the host and device PCI busses.
boards: the controller and I/O. The controller and I/O
circuit boards are connected using two 38-pin
controlled impedance connectors. The controller, I/O,
and ethernet circuit boards are assembled into a stack
with the controller and ethernet boards mounted to a
controller cover plate and the I/O board mounted to
the controller board. When the ethernet circuit board
is used, it is mounted to the controller circuit board.
Figure 4-1 shows the three circuit boards in their
relative positions.
Figure 4-1 RAID Controller Circuit Boards
2Gb SANbloc Series RAID Controller Introduction
49
Features of the RAID Controller include:
• Main processor coupled with a companion chip
• Proprietary XOR engine ASIC that provides data processing
XOR function and data cache SDRAM control
• Four 2Gb-capable fibre protocol chips for the device and host
ports
• Dual internal 528 MB/s, 64-bit, 66 MHz PCI buses
• Separate memory areas for processor and user data
• Scalable data cache memory: 128, 256, 512 MB DIMMs
• 128 KB NVRAM configuration memory
• Real Time Clock
• 4 MB Flash PROM
• Transparent failover/failback with multiple target ID support
The I/O circuit board includes a Battery Backup Unit (BBU)
that maintains memory content in case of AC power failure.
Power for the BBU is provided by a battery pack mounted in
the fan module of the enclosure.
RAID Controller Circuit Boards
This section gives a brief description of the three RAID
controller circuit boards: Controller, I/O, and Ethernet.
Controller Circuit
Board
The controller circuit board oversees and regulates the flow
of data from a host through the I/O circuit board to the disk
arrays in the 2Gb SANbloc enclosure. The controller circuit
board performs these operations with a proprietary archi-
tecture, using the following components:
• Main microprocessor and companion chip
• Control-store memory
• Memory Controller/Hardware XOR Engine ASIC (XOR ASIC)
• Flash PROM
• Non-volatile RAM (NVRAM)
• Dual universal asynchronous receiver/transmitter (DUART)
• Fibre Channel I/O processors
RAID Controller Circuit Boards
50
• Cache DIMM memory
I/O Circuit Board
The I/O circuit board provides the interface between the
enclosure and a host, as well as general support functions.
The I/O circuit board provides the following:
• Connections to the host
• Connections to the enclosure
• Dual switching power supply for +3.3 V and +2.5 V
• Hot pluggability for the controller
• Support for the BBU
The I/O circuit board has two SFF optical transceivers
supporting shortwave multimode fibre on the host side and a
90-pin controlled impedance (50 Ohm) connector on the
device side. An HSSDC connector with repeaters on the
expansion loop provides for a copper connection between
one of the device channels and an expansion module. Port
bypass circuitry on the I/O circuit board enables quadplex
operation on a second host loop. The I/O board has seven
LEDs to indicate subsystem status.
Ethernet Circuit
Board
The ethernet circuit board provides a 10BASE-T/100BASE-
TX LAN connection for out of band service for the RAID
controller. Features of the ethernet circuit board include:
• PCI ethernet controller chip
• Enhanced scatter-gather bus mastering
• Operation in either full duplex or half-duplex mode
• Auto-negotiation for speed, duplex, and flow control
• RJ45 ethernet connector with integral activity and link status
LEDs
The PCI ethernet controller is a fully integrated 10BASE-T/
100BASE-TX controller consisting of both the media access
controller (MAC) and physical layer (PHY) in one package.
RAID Controller Circuit Boards
51
It has a 32 bit, 33 MHz maximum PCI interface and features
scatter-gather bus mastering, which enables it to perform
high speed data transfers on the PCI bus. It operates in either
full duplex mode or half duplex mode. It has a four wire
interface to a serial EEPROM, which can provide power-on
initialization and software configuration.
The firmware interface is primarily through the PCI
interface, but a four-wire serial EEPROM interface can
provide power-on initialization. The diagnostic interface is
through the PCI interface.
The ethernet circuit board connects to the controller circuit
board through a 114 pin Mictor impedance controlled
connector. The electrical interface is with the primary PCI
bus (host bus) on the controller circuit board. In addition to
the PCI signals, this connector provides the 3.3 V power for
the ethernet circuit board. The power required for this board
is a maximum of 860 mA at 3.3 V, approximately 2.85 W.

RAID Controller Configurations
This section describes how to cable the two standard RAID
controller configurations: Single RAID Controller and Dual
RAID Controller (dual active). The procedure for daisy
chaining these standard configurations to expansions enclo-
sures is also described. This section also describes how to
set the enclosure ID.
Setting the Enclosure ID
Each of the fourteen disk drive slots of the SANbloc Series
has a unique identifier assigned to it. This identifier is
assigned using a combination of the Slot number and the
enclosure ID.
The enclosure ID is set, using the enclosure ID switch,
located on the rear of the SANbloc (see Figure 4-4).
Note: The enclosure ID must be set prior to powering on the
enclosure.
Note: Each enclosure must have a separate ID when daisy
chained together.

Chapter 5: System Monitoring
This Chapter describes the devices used to monitor the
2Gb SANbloc Series. The location of the monitoring LEDs
and how to interpret them is described.
Overview
The front mounted LS module is the main monitoring
device of the 2Gb SANbloc Series. This module is comple-
mented by status and fault LEDs, mounted on all the major
components of the enclosure, such as, disk drives, power
supplies, Advanced Cooling Modules (ACMs), and RAID
Controller. All these monitoring devices are discussed in the
following sections.
LS Module
The LS Module (Loop Resiliency and SES Module)
provides monitoring and control for the 2Gb SANbloc
Series. The module reports status and receives control infor-
mation over the Enclosure Services Interface (ESI) port of
any of the fourteen disk drives installed in the enclosure.
The LS Module also provides loop resiliency for the Fibre
Channel loop (in the form of Port Bypass Circuits).
The 2Gb SANbloc Series contains one LS Module as
standard. However, a second optional LS Module is
available to provide active/passive fail-over for the
enclosure services communication, and to provide a second
Fibre Channel Loop. Only one LS Module communicates
(using ESI communication) with the host system at any one
time, but both LS modules will continuously monitor the
Overview
66
system. If the active LS Module fails, then the ESI commu-
nication with the host system will be taken over by the
passive LS Module.
LS Module Features
• Monitoring/Control for 2 Power Supplies and 2 ACMs
• Reports status and receives control information via the FC loop
• Microcontroller for data processing, control and communica-
tions
• Volatile and non-volatile memory for the microcontroller
• Temperature sensor
• Audible alarm with manual and software disable
• FC link monitoring and status information
• Firmware download capability
• Reporting of PSU, LS module, I/O module, and backplane
serial number and revision
• I/O module and backplane type reporting
• Control of 6 front LEDs for enclosure and module status
• I/O option slot status monitoring
2Gb SANbloc
Enclosure LEDs
The 2Gb SANbloc Series has six LEDs located on each of
the front mounted LS Modules. These LEDs show the status
of the enclosure, power supply, Fibre Channel Loops, LS
Module status and the operating mode of the enclosure (1GB
or 2Gb operation). Figure 5-1 shows the location of the
LEDs
