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 2 GB of mirrored cache for high availability and is
protected by a battery powered cache offload mechanism. 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
