PowerEdge servers only support NVMe SSDs as boot devices when they use 512, 512e, or 4K sector sizes and the metadata size is set to 0 . Although it is possible to modify the default format type using non‑Dell utilities such as nvme‑cli , changing these settings is not supported by Dell Technologies for direct CPU‑attached NVMe boot devices. NVMe SSDs formatted with a non‑zero metadata size cannot be used for OS installation. On Linux systems, the installer does not list the drive. On Microsoft Windows systems, the drive appears with a reported size of 0.0 MB . Windows example: In Linux, the drive is not presented at all during operating system installation. The format type can be verified by inserting the drive into a system running a Linux operating system or by booting from a Linux ISO or USB device. In the example below, a non‑default Format: 2 with a metadata size of 8 is shown as active (in use) on the drive. The drive should be reconfigured to use the default Format: 0 or Format: 1 , as both use a metadata size of 0 .
The PowerEdge BIOS NVMe driver only supports a metadata size of 0 for boot drives.
PowerEdge systems using NVMe drives as boot devices must have the drives formatted with a metadata size of 0 .
