Okay, it might be a bit late and Paul [NAME] was pointing it out in an article he shared - but to keep a bit more information in this thread rather than on an additional outside ressource: The point is, that 12th gen Servers lack the NVMe drivers necessary to recognise a NVMe drive at BIOS/UEFI level. The drivers necessary for this awareness were AFAIK added only to the UEFI bioses of later gen models (iirc >= 13th generation). There is an NVMe Flash option available to the R720 line up, but it will not add boot support, as this option is built around a PCIe 3.0 x16 adapter (D P/N YPNRC ) that splits those 16 lanes into 4x4 lanes with each lane than being occupied by one NVMe flash drive. The drives are thus only presented via PCIe to the OS, but not to the BIOS/UEFI, as Daniel [NAME]-Daniel My states here Dell R720 with PCIe SSD-Backplane and Extender Card but no drives showing . So in short: there is NO direct way of booting NVMe drives on 12th gen DELL servers. However, you can do a simple trick to boot an OS stored on NVMe - and that's what Paul linked in his post: Boot to an (internal) USB/internal SD-card on which a boot loader like Clover resides. Add NVMe drivers to that boot loader to make the OS stored on your NVMe drive (e.g. a M.2 NVMe SSD connected via an adaptor in the back) visible to Clover. Clover will then boot from that NVMe drive. Kind regards and stay safeYannik
Hello Dell Community,I recently purchased a Dell R720 with the hopes of occupying the 8x HDD trays and booting off an NVMe drive within a PCIe adapter. After googling around, it seems this isn't possible, can anyone confirm this?The next option I tried was using this [URL] and replacing the DVD drive with a SATA SSD and unfortunately, that is not recognized at all as a device. Are there any other options with the R720 to add a boot drive (i.e SATA or NVMe) that isn't in the front of the chassis or am I stuck booting from a USB/SD Card?
