Configuring integrated SCSI hardware RAID components

The system supports hardware RAID through the storage I/O processor in conjunction with the LSI SCSI controller. The server platform supports RAID 0, 1, 5, and 10 configurations. Functionality for hardware RAID is enabled by using the following components:

RAID activation key (iButton)

RAID cache

There is also an option to install the RAID BBU (battery backup unit). If power to the storage I/O processor drops below specifications, the RAID BBU maintains the contents of the DIMM by keeping the DIMM in self-refresh mode until power is restored. After power is restored, data can be safely written to drives, maintaining the integrity of the disk array.
