Compute node drive configurations
The 5372 compute node contains 12 drive slots. The 5372 compute node contains three Opal-compliant SED only 1.92 TB NVMe 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 Flex application, and the logs. You can hot-swap one of these drives at a time if a drive becomes problematic. Replacements must be OPAL capable and of the same capacity.
The drives in slot 1 and slot 2 are configured as RAID1 with slot 3 as the hot spare. If a 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 drive and uses it to rebuild the RAID volume.
Table: 5372 compute node front panel drive configurations
Slot | RAID level | Drive size (TB) | Drive role |
|---|---|---|---|
D0, D1 | RAID1 | 1.92 TB - OPAL | Operating system and log volume |
D2 | RAID1 | 1.92 TB - OPAL | Operating system/log hot spare |
D3-D11 | N/A | N/A | Empty Carrier |
