Just installed the DC P3700 PCI-e in a HP DL360 G6, which only has a PCI-e 2.0 slot. I have RHEL 6.5 installed on the box (with RH's latest RHEL6.5 kernel).
We are not seeing the device.
"isdct show -intelssd" returns "No results".
I'll keep playing around with it, but it doesn't appear that the SSDPEDMD400G401 is backwards compatible with PCI-e 2.0.
Any other things I can try?
Do you know if I need a system with UEFI 2.3.1 to support the DC3700 if I DON'T need it to boot?
We are fine with booting off of our normal harddrives, and want to use the DC3700 for db files.
I'm trying to get the SSDPEDMD400G401 working on a PCI-e 2.0 system and don't have any luck yet. We are running RHEL6.5.
I can only tell you what I have seen.
Intel DX58SO board latest available bios = 3 beeps (memory missing) but works fine when I remove the card
DQ57TM = same
DQ67EP (PCIe 2.0) = works with latest available bios and 64bit Windows plus PCIe NMVe driver
DH77MK? = works
I haven't tried Linux but I expect your difficulty is bios and hardware not the OS.
