(a) 24 and 48 drive arrays implement multiple RAID 6 sets within a single chassis.
(b) 48 drive arrays cannot implement a no hot-spare RAID policy.
(c) PS60x0 XVS with 8x 100GB SSD and 8x 450GB SAS.
(d) One 450GB hot spare, 2x 450 GB parity and 2x 100GB SSD parity. In the event of a drive failure (SSD or SAS), the
RAID set is reconstructed using the 450GB SAS hot spare.
(e) One 600GB hot spare, 2x 600 GB parity and 2x 400 GB SSD parity. In the event of a drive failure (SSD or SAS), the
RAID set is reconstructed using the 600 GB SAS hot spare.
(f) PS4100/PS6100 models only
Total reported usable storage when using hot spares: All models prior to PS4100/PS6100
