About 3340 compute node disk drive configurations
The Access 3340 Appliance compute node contains three 2 TB SAS hard disk drives. Each disk drive is accessible from the compute node's front panel. An embedded RAID controller on the compute node's mainboard configures two of the three disk drives into a mirrored RAID1 volume.
The RAID1 volume is labeled Volume 0. The disk drives that are located in slot 0 and slot 1 are configured as the RAID1, VOLUME0 device. These disk drives contain the appliance operating system, the operating system swap file, and the Veritas Access application. 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 appliance uses the disk drive that is located in slot 2 as a hot-spare disk. If a disk drive in RAID Volume0 experiences a hardware error, the appliance automatically initiates a RAID rebuild operation. During the rebuild operation, the appliance dynamically accesses the hot-spare disk from slot 2 and uses it to rebuild the RAID volume.
