Note: RAID 50 is not available through the Group Manager UI on PS6610 arrays.
7.4 RAID 5 drive layouts and total reported usable storage
RAID 5 (striped disks with distributed parity) will combine N disks in an arrangement where each stripe
consists of N–1 disks that contain data blocks plus 1 disk that contains a parity block. For each stripe, the
parity block will be placed on a different disk ensuring that the parity blocks are not located on a single disk in
the RAID set. RAID 5 implementations can tolerate a single drive failure without data loss.
Table 25 shows the drive layouts that are enforced when using a RAID 5 policy based on the number of
drives in each array/hot spare configuration, and the total usable storage available for each model.
Note: RAID 5 is not supported for PS6210. To configure RAID 50 with drives larger or equal to 3TB, or RAID
5 with drives of any size, you must use the Group Manager CLI.
