Compute node disk drive configurations
The Veritas 5350 Appliance compute node contains three 1.92 TB SATA SSDs. Each SSD is accessible from the compute node's front panel. An embedded RAID controller on the compute node's mainboard configures two of the three SATA SSDs into a RAID1 volume.
The two RAID1 volumes contain the appliance operating system, the operating system swap file, the NetBackup application, and the logs. You can hot-swap one of these disk drives at a time if a drive becomes problematic. However, you cannot operate the appliance if both disk drives are removed.
The disk drives in slot 1 and slot 2 are configured as RAID1 with slot 3 as the hot spare. If a disk drive in the RAID volume experiences a hardware error, the appliance automatically initiates a RAID rebuild operation. During the rebuild operation, the appliance dynamically accesses the hot-spare disk and uses it to rebuild the RAID volume.
Table: Veritas 5350 Appliance compute node front panel disk drive configurations
Slot | RAID level | Disk drive size (TB) | Disk drive role |
|---|---|---|---|
0, 1 | RAID1 | 1.92 TB | Operating system and log volume |
2 | RAID1 | 1.92 TB | Operating system/log hot spare |
3-7 | RAID1 | - | blank |
