Fault Tolerance RAID
Descriptions
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.
NOTE:
Please see the HP P2000 G3 Modular Smart Array Systems QuickSpecs for Technical Specifications

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.
Ease of Use
Consistency and Upgradeability make the Smart Array family unique in the industry:
