I need a low profile PCI-E card that allows for up to 2 M.2 SSD drives that is known to work with the stock kernel in CentOS 7.
Can anyone recommend one?
I can't recommend a specific one, but any adapter card should work. However, note that M.2 is not a single "thing" to the computer; the drive interface can be SATA, PCI-E AHCI, or PCI-E NVMe. The first two would look the same as a traditional SATA device to the OS, so should be fine. The third is a different interface; I haven't looked to see if the CentOS 7 kernel supports NVMe (I suspect it does, but you should check before buying an NVMe device). I know that NVMe works fine with recent Fedora.
To add a data point, I built a stock CentOS 7.3 VM in ESXi 6.5 with hardware version 13 to include NVMe support. The VM boots and runs great on the virtual NVMe controller.
