What RAID configurations does the Snap Server (GuardianOS) support? ---Solution---
RAID 0 (Striped)
A RAID 0 stores equal portions of each file on each disk in the RAID Set.
RAID 1 (Mirrored)
A RAID 1 uses mirroring, which stores data on one disk and copies it to a second disk, creating a redundant storage solution.
RAID 5 (Striping with Parity)
RAID 5 stores equal portions of each file on each disk and distributes parity information (error correction data) for each file across all disks in the group. This distributed parity allows the system to recover from a single disk drive failure.
By default, the 14000 is preconfigured with an 11-disk RAID 5 and one hot spare -- a single volume and one share point. The data space is preconfigured to allocate 250 GB to Snapshots on the single volume and the remainder of the RAID for the live file system.
