Drive guidelines

Depending on the configuration, the server supports SAS, SATA, and NVMe drives.

Observe the following general guidelines:

• The system automatically sets all drive numbers.
• If only one hard drive is used, install it in the bay with the lowest drive number.

  For drive numbering, see Drive bay numbering.

• The NVMe SSD is a PCIe bus device. Devices attached to a PCIe bus cannot be removed without allowing the device and bus to complete and cease the signal/traffic flow.

  Do not remove an NVMe SSD from the drive bay while the Do Not Remove button LED is flashing. The Do Not Remove button LED flashes to indicate that the device is still in use. Removal of the NVMe SSD before the device has completed and ceased signal/traffic flow can cause loss of data.

• Drives with the same capacity provide the greatest storage space efficiency when grouped into the same drive array.
