From what I’ve found online 12th series PowerEdge servers don’t have the required firmware to boot from PCIe on NVME. As there is no bifurcation support.
However I’m trying to figure out if I can use a PCIe m.2 to SSD adapter if this could work for a boot drive or not. Or alternatively PCIe to SSD adapter.
Everything I’m fining online is about making NVME work. With no word on SATA adapters.
Some adapters are strictly over the PCIe bus. Some have SATA cables you can plug into the adapter board then into the motherboard.
Will either of these work? Original question on Reddit.
