Standard Features
Fault Prevention
The following features offer detection of possible failures before they occur, allowing preventive action to be taken:
• Predictive drive failure detects possible drive failure before it occurs, allowing replacement of the component before failure occurs.
• Background surface scan checks drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
• HPE SmartSSD Wear Gauge reports the amount of lifetime remaining on your SSDs.
Fault Recovery
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
• Recovery ROM: This feature protects the user from a firmware image corruption by storing a redundant copy of the firmware image. If the active firmware image becomes corrupt, the controller will use the redundant firmware image and continue operating.
• 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 detects and corrects data bit errors
