Data Retention

Non-volatile solid state disk

Redundant internal batteries power the system for 25 minutes after power loss

Automatically backs up data to disk at 190 MB/sec

Reliability and Availability

Chipkill technology protects data against memory errors up to and including loss of an entire memory chip

Internal redundancies

   - Power supplies and fans

   - Backup battery power (n+1)

   - Backup hard disk drives (RAID3)

Hot-swappable components

   - Four backup hard drives (front access)

   - Power supplies

Soft Error Scrubbing

   - When a single bit error occurs on a read, the RamSan will automatically

      re-write the data to memory thus scrubbing soft errors. Following

      the re-write the system re-reads to verify the data is corrected.

Backup Procedures

Supports two backup modes that are configurable per system or per LUN:

Data Sync mode - synchronizes data to redundant internal disk drives before shutdown or with power loss

Active Backup® mode (optional) - backs up data constantly to internal redundant disks without impacting system performance.
