Available appliance storage options
The Access 3340 Appliance compute nodes do not contain internal disk space on which to store data. Instead, the 3340 Appliance system uses one required 5U84 Primary Storage Shelf and up to three optional 5U84 Expansion Storage Shelves as the main data storage devices. The 5U84 Primary Storage Shelves connect to 3340 Appliance compute nodes and use RAID 6 drive sets to protect the stored data.
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.
Refer to the following table for available storage capacity for the 3340 Appliance using 4-TB and 10-TB disk capacities.
Note:
Each storage shelf must contain disk drives of the same capacity. Veritas does not support mixing 4-TB and 10-TB disk drives within a storage shelf.
