Chapter 1. Overview The IBM FAStT500 RAID Controller Enclosure Unit (referred to throughout this book as controller unit) is a high-performance unit that provides dual, redundant RAID controllers and Fibre Channel interfaces to both the host and drive channels. Controller unit overview The controller unit supports direct attachment of up to four hosts containing two host adapters each, and is designed to provide maximum host- and drive-side redundancy. Using an external hub, the controller unit can support up to 64 host adapters per controller (up to 128 host adapters per controller unit). Each controller unit 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, controller fan, power supplies, fan and communications module, mini-hubs, and Gigabit Interface Converters (GBICs). The controller unit also has a removable front bezel. Front view Figure 1 on page 2 shows the controller unit front view and the following components: • Bezel - Removable front cover with holes for viewing the status lights and for boosting air circulation. • Controller fan - One removable unit that contains two cooling fans and status indicator lights. • Battery - One removable unit that contains a battery and battery charger circuitry. • Controllers - Two removable units, each contains one RAID controller. © Copyright IBM Corp. 2000, 2002 1

Chapter 1. Overview
The IBM FAStT500 RAID Controller Enclosure Unit (referred to throughout this book as
controller unit) is a high-performance unit that provides dual, redundant RAID controllers
and Fibre Channel interfaces to both the host and drive channels.
Controller unit overview
The controller unit supports direct attachment of up to four hosts containing two host
adapters each, and is designed to provide maximum host- and drive-side redundancy.
Using an external hub, the controller unit can support up to 64 host adapters per controller
(up to 128 host adapters per controller unit).
Each controller unit 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, controller fan, power supplies, fan and
communications module, mini-hubs, and Gigabit Interface Converters (GBICs). The
controller unit also has a removable front bezel.
