Fault Recovery
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
Recovery ROM: This new feature provides a unique redundancy feature 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.
On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive
failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed
automatically.
DRAM ECC corrects against single bit data and address corruption.
Battery-backed write cache upgrade provides for up to two days of battery power for data cache
retention. The data backup duration could be extended anytime the server's auxiliary power is
available during system power down.
Flash Backed Write Cache upgrade provides indefinite data retention.
