1.10 StorageWorks Controller Subsystem Products
Digital offers several preconfigured HS array controller subsystems. However,
if you wish to customize your own system, read the StorageWorks Solution
Configuration Guide and the StorageWorks Solutions Shelf and SBB User’s Guide
for guidance in creating a customized, configure-to-order (CTO) subsystem.
CAUTION
If you decide to install SCSI–2 devices that have not been qualified by
Digital for use with your array controller, the performance and correct
operation of those devices or the controllers may not be satisfactory and is
not guaranteed by Digital.
Snap-in SBBs can provide power, controllers, storage, adapters, and battery
back-up units (BBUs). Not all SBB types are supported by each type of HS
array controller. Refer to HS array controller model-specific software product
descriptions (SPDs) and release notes for supported device lists.
Most of the Digital’s SBB devices come in either a 3½-inch or a 5¼-inch SBB as
shown in Figures 1–5 and 1–6.
