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.
