Chapter 1. Introduction
The IBM TotalStorage FAStT700 Fibre Channel Storage Server (referred to
throughout this book as FAStT700 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.
FAStT700 Storage Server overview
The FAStT700 Storage Server (Machine type 1742, models 1RU and 1RX) supports
direct attachment of up to four hosts containing two host adapters each, and is
designed to provide maximum host-side and drive-side redundancy. Using external
Fibre Channel switches in conjunction with the FAStT700 Storage Server, you can
attach up to 64 hosts with two adapters each to a FAStT700 Storage Server.
Each FAStT700 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 FAStT700 Storage Server also has a
removable front bezel.
The FAStT700 Storage Server functions with at least one external Fibre Channel
drive enclosure containing Fibre Channel hard drives. The FAStT700 Storage
Server supports 224 Fibre Channel hard drives. If the Fibre Channel drives are
configured in a FAStT EXP500 expansion unit, a maximum of 220 drives are
supported.

Figure 1 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. Figure 2 on
page 2 shows the FAStT700 Storage Server without the front bezel, showing the
following components:
v
Storage server fan - A removable unit that contains two cooling fans and
indicator lights.
v
Battery - A removable unit that contains the cache battery for the controllers,
battery charger circuitry, and status indicator lights.
v
