Managing VMD
The Intel Volume Management Device (VMD) is a module integrated in the processor on the Purley platform. It is used for surprise hot plug, management, and error processing of SSDs.
- To use the VMD function, the iBMC version must be V320 or later, and the BIOS version must be V110 or later. Otherwise, the iBMC WebUI may fail to display NVMe drive information and the fan speed cannot be adjusted based on the NVMe drive temperature, affecting the heat dissipation of NVMe drives.
- The VMD function must be enabled on the BIOS in UEFI mode only. The BIOS in legacy mode does not support this setting.
- If the VMD function is enabled and the latest VMD driver is installed, the NVMe drives support surprise hot swap. If the VMD function is disabled, NVMe drives support orderly hot swap.
