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)
