Note:
RAID 6 is also known as double-parity RAID. It uses two parity stripes on
each disk to protect data. RAID 6 allows for two hard disk failures within the RAID
disk array before any data is lost.
If additional data storage space is required, you can connect up to three optional
Veritas 5U84 Expansion Storage Shelves to the existing 5U84 Primary Storage
Shelf. The 5U84 Expansion Storage Shelves connect to the 5U84 Primary Storage
Shelf using SAS3 data cables. After connecting the shelves, the disk drives in the
5U84 Expansion Storage Shelf use RAID 6 sets that are controlled by the 5U84
Primary Storage Shelf to protect the stored data.

Appliance running NetBackup software using 4-TB and 8-TB disk capacities.
Note:
Veritas does not support mixing 4TB and 8TB disk drives within a storage
shelf.
