3211 Drive Bay Options
CS500 model 3211 drive bay configurations.
The CS500 model 3211 compute node supports different drive bay configurations depending on the server model and accessories.
The drives may be hot-swapped while the chassis power is applied, but you must take caution before hot-swapping while the compute module is functioning under operating system/application control or data may be lost. Replace a faulty drive only with one from the same manufacturer with the same model and capacity.
Drive numbering. The figure shows numbers/groups for drives routed to the same compute node through the backplane. These numbers/groups are not indicated on the hardware.
- 2.5in drives
- 4x SATA (6Gb/s) / SAS (12Gb/s)
- 24x SATA (6Gb/s) / SAS (12Gb/s)/ NVMe (8 total, max. 2 per node)
- 3.5in drives
- 12x SATA (6 Gb/s) / SAS (12Gb/s)
For 24 x 2.5in drive configurations, the drive bay supports 12Gb SAS or 6Gb SAS drives. The SAS drives are hot‑swappable. The front side of the backplane includes 24 drive interface connectors. All the 24 connectors can support SAS drives, but only the connector #4 and #5 of each compute module are capable of supporting PCIe SFF devices. Two different drive carriers are included in the drive bay. Drive carriers with a Blue latch are used to identify support of PCIe SFF devices or SAS drives. Drives carriers with a Green latch are used to identify support of SAS drives only.
NVMe SSDs have hot swap / hot plug capability. Support and usage models are OS dependent.
For a given compute node, any combination of NVMe and SAS drives can be supported, as long as the number of NVMe drives does not exceed two and they are installed only in the last two drive connectors on the backplane (4 and 5) and the remaining drives are SAS drives (0, 1, 2, 3).
Do not mix or alternate NVMe and SAS drives.
