Keeps data available and server running while a failed drive is being replaced; two fault tolerance
configurations are supported for the internal connections including:
RAID 0 (striping) provides no extra data protection. Data is striped across all drives in the array to
increase performance. RAID 0 requires a minimum of one drive.
RAID 1 (mirroring) protects against failure of one drive. Data is duplicated on a pair of drives.
RAID 1 requires a minimum of two drives.

Fault Recovery

Fault Recovery Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure:
Recovery ROM: This feature provides unique redundancy that protects from a ROM image
corruption. A new version of firmware can be flashed to the ROM while the controller maintains
the last known working version of firmware. If the firmware becomes corrupt, the controller will
revert back to the previous version of firmware and continue operating. This reduces the risk of
flashing firmware to the controller.
DRAM ECC corrects against single bit data and address corruption.
