xxiv IBM TotalStorageFAStT900 Fibre Channel Storage Server: User’s Guide
Chapter 1. Introduction
The IBM TotalStorage FAStT900 Fibre Channel Storage Server (referred to
throughout this book as the FAStT900 Storage Server) is a high-performance unit
that provides dual, redundant array of independent disks (RAID) controllers and
Fibre Channel interfaces to both the host and drive channels.
FAStT900 Storage Server overview
The FAStT900 Storage Server (Machine type 1742, models 90U and 90X) supports
direct attachment of up to four hosts that contain two host adapters each, and is
designed to provide maximum host-side and drive-side redundancy. By using
external Fibre Channel switches in conjunction with the FAStT900 Storage Server,
you can attach up to 64 hosts with two adapters each to a FAStT900 Storage
Server.
Each FAStT900 Storage Server contains several removable components, called
customer replaceable units (CRUs), that you can access from either the front or
back of the unit. These CRUs include the battery, RAID controllers, storage server
fan, power supplies, fan and communications module, mini hubs, and Small
Form-Factor Pluggable (SFP) modules. The FAStT900 Storage Server also has a
removable front bezel.
The FAStT900 Storage Server functions with at least one external Fibre Channel
drive expansion unit containing Fibre Channel hard drives. The FAStT900 Storage
Server supports a maximum of 224 Fibre Channel hard drives when using an IBM
FAStT EXP700 drive. If the Fibre Channel drives are configured in FAStT EXP500
drive expansion units, a maximum of 220 hard drives are supported.
Front view
Attention: The FAStT900 controller units are not compatible with the FAStT700 or
FAStT500 controller units. The FAStT900 controller units are keyed to prevent them
from being mistakenly inserted in the non-supported storage server units. Do not
force fit the controller units or the backplane might be damaged.
Figure 2 on page 2 shows the bezel. The bezel is a removable front cover with
holes for viewing the status lights and for boosting air circulation.
Note: The illustrations in this document might differ slightly from your hardware.

Figure 4 on page 3 shows the FAStT900 Storage Server back view and the
following components:
v Host-side and drive-side mini hubs - Up to eight removable mini hubs with
indicator lights. You can insert SFP modules into the mini hubs and connect
fiber-optic host and drive interface cables to the FAStT Storage Server. (The
standard FAStT900 configuration includes two host and two drive mini hubs.)
v Power supplies - Two removable units that each contain a power supply and an
indicator light.

Fibre Channel connections
When fully configured, the back of the FAStT900 Storage Server can accommodate
up to four host-side and four drive-side mini hubs. Each mini hub is a single,
removable unit that provides the Fibre Channel interface between a FAStT900
Storage Server, host computers, and drives. Each mini hub has two SFP module
ports. An SFP module is inserted into a mini-hub port. Figure 5 shows the Fibre
Channel components.

Chapter 1. Introduction 3
The FAStT900 Storage Server uses fiber-optic cables to connect to other Fibre
Channel devices. The fiber-optic cables that you need depend on the type of optical
connectors in the device to which you are connecting the FAStT900 Storage Server.
If the device uses SFP modules or optical interface connectors, then you must use
LC-LC Fibre Channel cables. If the device uses Gigabit Interface Converters
(GBICs) as the optical interface connector, you must use LC-LC Fibre Channel
cables and LC-SC Fibre Channel cable adapters (Part number 19K1250) to connect
to the FAStT900 Storage Server.
Handling fiber-optic cables
Before you use fiber-optic cables, read the following precautions.
Attention: To avoid damage to your fiber-optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
v When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
v Route the cable away from places where it can be damaged by other devices in
the rack cabinet.
v Do not use plastic cable ties in place of the provided cable straps.
v Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v Do not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
Using LC-LC Fibre Channel cables
The LC-LC Fibre Channel cable is a fiber-optic cable that is used to connect into
one of the following devices:
v SFP module installed in a FAStT900 Storage Server mini hub
v SFP module installed in an IBM Fibre Channel switch
v SFP module installed in an IBM FAStT EXP700 drive expansion unit
v Optical interface connector on an IBM FAStT FC–2 Host Bus Adapter (part
number 19K1246), IBM FAStT single port FC2-133 Host Bus Adapter (part
number 24P0960), or dual port FC2-133 Host Bus Adapter (part number
24P8053)
Figure 6 on page 5 shows an LC-LC Fibre Channel cable.
