This chapter describes the operating specifications, features, and components for
the IBM TotalStorage
®
EXP100 Storage Expansion Enclosure (hereafter referred to
as EXP100 or “expansion enclosure”). This chapter also lists the hardware that
comes with the expansion enclosure, and lists the ESM and controller firmware that
is required to enable support for the EXP100.
This chapter contains the following sections:
v “Overview”
v “Software, hardware and firmware compatibility and upgrades” on page 4
v “Inventory checklist” on page 14

The IBM TotalStorage DS4000 EXP100 Storage Expansion Enclosure is designed
for data archival, data reference, and near-line storage applications and enables the
attachment of Serial Advanced Technology Attachment (SATA) disk drives for
DS4000 storage subsystems such as the DS4100, DS4300, DS4400, DS4500, and
DS4800.

EXP100 storage expansion enclosure - description
|
|
|
|
|
|
|
The EXP100 is a rack-mountable storage expansion enclosure that supports up to
fourteen 1.5 Gbps 400 GB SATA disk drive modules, offering up to 5.6 terabytes
(TB) of capacity per expansion enclosure.
Note: There are two EXP100 machine types:
v 1710 (model 10X or 10U)
v 1724 (model 1Xx, where x is an alphanumeric character)
Coupled
with DS4000 storage subsystems such as the DS4100, DS4300, DS4400,
DS4500, and DS4800, you can configure RAID-protected storage solutions of up to
89.6 TB, providing economical and scalable storage for your rapidly growing
application needs for limited-access, data-reference storage capacity.
The EXP100 utilizes the latest SATA disk drive technology and is designed with
redundant 2 Gbps Fibre Channel connections to the DS4000 storage subsystem,
offering reliability and performance.
© Copyright IBM Corp. 2004, 2005 1
The EXP100 supports redundant, dual-loop configurations with the DS4000s and
other EXP100 units. External cables and small form-factor pluggable (SFP) modules
connect the controller to the expansion enclosure. EXP100s attached to supported
DS4000s can be used with storage area networks to satisfy the needs of various
fixed content, data reference applications that require large amounts of storage
capacity but do not have the high utilization and access characteristics satisfied by
Fibre Channel disk drive storage. The expansion enclosure provides continuous,
reliable service and uses hot-swap technology for easy replacement without the
need to shut down the system. Up to eight EXP100 units can be connected
together in a Fibre Channel loop, providing connections to a maximum of 112 hard
drives.

There are three types of EXP100 Environmental Storage Canister (ESM) CRU
firmware - R1, R2, and R3. The current EXP100 release is shipped with R3
ESM firmware, which enables the support of the new 400 GB SATA drive
option (P/N 39M4570) 400 GB CRU/FRU (P/N 39M4575), and the new 250
GB S ATA drive CRU/FRU (P/N 40K6837).
|
|
|
|
|
|
|
|
In addition to these firmware types, there are four different release levels of
DS4000 controller firmware/NVSRAM that are associated with the three
EXP100 ESM firmware types.
Before you install and configure your EXP100, read the detailed information
about these DS4000 firmware release levels and EXP100 ESM CRU firmware
types in “Software, hardware and firmware compatibility and upgrades” on
page 4. The information in that section is essential to successfully completing
an EXP100 installation.

Fibre Channel defined
Fibre Channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre Channel is a high-speed data transport technology that
is used for mass storage and networking.

Using a Fibre Channel arbitrated loop (FC-AL), more than 100 Fibre Channel
devices
1
can be supported, compared to 15 small computer system interface
(SCSI) devices. The connection from the DS4000 to the EXP100 is a 2 GB Fibre
Channel device that supports data transfer rates up to 200 MBps half-duplex and
400 MBps full-duplex on optical interfaces.
The Serial Advanced Technology Attachment (SATA) interface offers increased data
rate performance over Parallel Advanced Technology Attachment (ATA), while
maintaining the benefits of ATA. SATA is designed to overcome the performance
barriers that have been forecasted for current parallel technologies while
maintaining the cost-efficiency of Parallel ATA . SATA specifications allow for thinner,
more flexible cables, and lower pin counts. It also enables easier, more flexible
cable routing management and the use of smaller connectors than is possible with
the existing Parallel ATA technology.
The Serial ATA Working Group introduced the first SATA specification, Serial ATA
1.0, in 2001. See the following Web site for more information:
www.serialata.org
The latest EXP100 storage expansion enclosure is shipped with Environmental
Card Canister (ESM) R3 firmware. This R3 ESM firmware release supports the
following new features:
v The new 400 GB SATA drive option (P/N 39M4570) and CRU (P/N 39M4575)

firmware and ESM firmware upgrades concurrent with I/O activity.
Recommendation: IBM strongly recommends that you check and maintain the
DS4000 storage subsystem controller firmware and EXP100 ESM firmware at the
latest levels, even if you do not have any 400 GB drive options in your DS4000
configuration. This ensures compatibility when you need to replace existing S ATA
hard drives with the new drive options or SATA drive CRUs, and provides the latest
available quality enhancements.

Upgrade the host management software to DS4000 Storage Manager version 9.15,
or later, in the host servers and in the management station.
You can find the latest DS4000 controller firmware and NVSRAM, EXP100
expansion enclosure ESM firmware, and Storage Manager software packages at
the IBM DS4000 TotalStorage Support Web site:
www.ibm.com/servers/storage/support/disk/
The software and firmware are also included on the DS4000 Storage Manager
version 9.15 Support for Microsoft Windows 2000, Windows Server 2003 CD that is
shipped with the EXP100. However, always check the Web site to be certain that
you have the latest versions.
Note: To enable functionality that is specific to DS4000 Storage Manager Version
9.1x, you must install controller firmware versions 06.1x.xx.xx on the DS4000
storage subsystem. See the next section for detailed information about
firmware.
Even though your DS4000 storage subsystem is shipped with the latest firmware
available at the time of shipping, always check the IBM DS4000 TotalStorage
Support Web site (listed below) to ensure latest controller firmware and ESM
firmware for your DS4000 storage subsystem. This is to ensure the compatibility of
your DS4000 storage subsystem with the replacement drive CRUs in the event of
SATA hard drive failures.
