-
Set Name.
-
Set RAID Level.
-
If cross-controller RAID is required, select Enable RAID spanned over VMD Controller.
-
Select specific disks for RAID with an [X].
-
RAID0: Select at least two [2–24] disks
-
RAID1: Select only two disks
-
RAID5: Select at least three [3–24] disks
-
RAID10: Select only four disks

Hot-Swap Drives
Intel VMD enables hot-plug and hot-unplug for NVMe SSDs, whether from Intel or other manufacturers. Under vSphere ESXi, several steps are necessary to avoid potential stability issues. See the information at link [1] below.
Hot-Unplug
-
Prevent devices from being re-detected during rescan:
esxcli storage core claiming autoclaim --enabled=false
-
Unmount the VMFS volumes on the device. Check link [2] below for details.
-
Detach the device. Check link [3] below for details.
-
Physically remove the device.
Hot-Plug
-
Physically install the device.
ESXi will automatically discover NVMe SSDs, but a manual scan may be required in some cases.
