Hi,
I have purchased some Connect-X 2 MHRH2A-XSR forum an ebay seller which listed it as 40GB/10gbe
Some other seller report me these boards are only 10gb/10gb, someother 20gb/10gb

Which is the true version ?

I have a few of these, and they are DDR, 20Gb/s. I use them in IB mode with srv2012r2; they even support RDMA once you upgrade the F/W.

Well, I couldnt find the exact modell on a quick search, but

MHRH2A-XTR

Rev X3:
MT_0F90120008 Dual QSFP VPI DDR Port with NCSI, PCIe Gen2 x8 2.0 (5GT/s), Tall Bracket, RoHS-R6 HCA Card, QSFP Connectors

Which supports the DDR statement from @poto

Its a VPI card so it should support EN.
I'd assume it will do 20 IB per interface and 10 per interface on EN.
If you can team that you can double total throughput but I dont think so (at least not for IB, maybe in EN mode)

Hi, I recently got the same card recently to explore Infiniband but I'm struggling to make it work whether in Windows 7 or Ubuntu...

[root@localhost ~]# mstflint -d 0b:00.0 q

Does anyone have a FW / driver combination that works ? I'm just looking for some guidance to get started.
