NVMe SSD Requirements and Restrictions
NVMe SSD Requirements and Restrictions

• NVMe PCIe SSDs cannot be controlled with a SAS RAID controller because NVMe SSDs interface
• UEFI boot is supported in all supported operating systems.
Hot Plug Considerations
Enabling Hot Plug Support
Surprise and OS-informed hot plug is supported with the following conditions:
• VMD must be enabled to support hot plug. VMD must be enabled before installing an OS on the drive.
• If VMD is not enabled, surprise hot plug is not supported, and you must do OS-informed hot plug instead.
• VMD is required for both surprise hot plug and drive LED support.
