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.

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

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.

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.

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?)

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

[CentOS] M.2 PCI-E card

[Alice Wonder]

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
