Introducing the Controller Enclosure
1–5
Enclosure Power
One 180 W power supply adequately supports enclosure functions. A second power
supply provides redundancy. Using two 180 W power supplies in the enclosure eliminates
the power supply as a single point of failure.
CAUTION:
Proper enclosure operation
requires
power supplies rated for at least
180 W.
Controller Sets
The enclosure accommodates up to two controller sets. Each controller set is composed of
an array controller, a cache module, and an ECB.
CAUTION:
Proper cache module operation requires an ECB module for each cache.
Refer to the array controller documentation for information about using controller sets
and ECBs.
The following Compaq StorageWorks array controller types function properly within the
enclosure, using controller-compatible cache memory and a supported array controller
software (ACS) version:
■
Model 2100 enclosures — any supported 2-port array controller, such as the HSG60
■
Model 2200 enclosures — any supported 6-port array controller, such as the HSG80
Various cabling configurations can be used to connect an array controller to a host. Refer
to array controller documentation for cable configuration information.
Storage CRUs
The enclosure does not support the installation of storage devices within the enclosure.
