enclosure with dual RAID controllers and two power supply/cooling fan

modules is shown. However, a single RAID controller module is supported,

and the enclosure can run temporarily on one power supply/cooling fan

module. For more information, see "Power Supply and Cooling Fan Features"

RAID Controller Modules

The RAID controller modules provide high-performance, advanced virtual

disk configuration, and fault-tolerant disk subsystem management. Each

RAID controller module contains 512 MB of cache that is mirrored with the

other controller's cache for high availability and protected by a battery for up

to 72 hours.
