Hello list,
My instinct says the vast majority will "just work" but I'll ask anyway.
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?
Thanks

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.
Also note when choosing an adapter; the M.2 slot is keyed different for the different device types, so make sure you get an adapter that matches your device.

Thanks! I ordered a 2.5" SATA drive and they screwed up and sent me M.2 - I'll be sure to look at the booklet (Intel SSD 5 but there may be more than one variant?)

Intel 5 series SSDs use SATA interface, so the discussion about NVMe support doesn't apply in this case. You can use an adapter like this to mount it in a 2.5" drive slot: http://preview.tinyurl.com/lm4952g

Links like http://amazon.com/dp/B00ITJ7U20 or http://amazon.com/dp/B00PY11SYM might last longer (for archived mail list purposes) than auction site links, which are typically inaccessible 90 days or less after the listing ends.

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.

Not perhaps absolutely definitive, but the Dell configurator allows you to specify RHEL7.2 with the Dell branded NVMe PCIe M.2 drives - it doesn't allow the Intel PCIe NVMe SSD cards though. It's happy with non-NVMe M.2 drives.
