Shelf Cabinet
The controller shelf can be mounted in a StorageWorks metric or RETMA
style cabinet. You must install the appropriate shelf rail kit hardware to
properly mount the shelf in the cabinet. The RETMA rail kit is supplied with
the shelf and contains the installation guide, which describes the installation
procedure. The rail kit for a metric cabinet is optional.
The commercial UPS supplied with the controller shelf is installed in the
cabinet using a custom set of mounting brackets designed to accommodate
either a metric or RETMA style cabinet. The bracket has two sets of mounting
holes at each end, which allows its installation into either cabinet.
RAID Array 3000 Controller
The controller shelf (Figure 1– 4) contains Wide-Ultra SCSI/differential host
channels and Wide-Ultra SCSI/single-ended disk channels. In dual-controller
configurations, the controllers support fully automatic and smooth controller
failover in the event of a RAID controller fault.

The controller shelf supports one (for a single controller) or two (for dual-
controllers) standard 72-pin caches Single Inline Memory Modules (SIMMs)
of up to 32 MB. In a dual-controller setup, both controllers must have identical
cache configurations and the total usable cache (per controller) will be half the
amount installed due to mirroring. Thus, in a single controller setup the
maximum usable cache is 64 MB, while a redundant setup has a maximum
usable cache of 32 MB (per controller).
