Configuring Intel Vmd; Configuring Vmd Manually - Supermicro SuperServer 621H-TN12R User Manual

Configuring Intel VMD

VMD must be enabled on PCIe ports which have NVMe drives attached to them in order for
those drives to be added to a VROC RAID configuration. The default BIOS setting for the
NVMe Mode Switch is Auto which automatically enables VMD on all installed NVMe drives.
NVMe Mode Switch :
•
Auto
Enables VMD for all NVMe ports if VROC Key is installed.
•
VMD Enables VMD for all NVMe ports despite the lack of the VROC Key.
•
Manual Allows the user to select specific NVMe ports on which to enable VMD.
The NVMe Mode Switch can be viewed or selected at BIOS > Advanced > Chipset
Configuration > North Bridge > IIO Configuration > Intel® VMD Technology.
Note: Without a VROC Key, there is no RAID support with the Auto switch. Only RAID 0 is
supported with the VMD and Manual switches.
