RAID Controller Modules
RAID controller modules provide high-performance, advanced virtual disk configuration, and fault-
tolerant disk subsystem management. Each RAID controller module contains 4 GB of mirrored cache for
high availability and is protected by a battery powered cache offload mechanism.
NOTE: 8 GB mirrored cache is an optional feature.
RAID controller modules provide the following data path and enclosure management functions:
• Monitoring and controlling enclosure environment elements (temperature, fans, power supplies, and
enclosure LEDs)
• Controlling access to the physical disks
• Communicating enclosure attributes and states to the host server and management station
