RAID 6 Configuration
RAID 6 uses block-level striping with two parity blocks distributed across all member disks. Dual parity
provided by a RAID 6 configuration ensures that your data retains full integrity even in the event of two hard
drive failures. .
The DXi6900-S uses RAID 6 volumes for data storage (see
