I got some time (finally after a year or something) to try to play with some of the Mellanox ConnectX-3 i bought for cheap.
On my HP t730, it won't even detect the device on PCIe bus, but i have 2 other Haswell corei i3/i5 systems that do detect it, but unfortunately, i can't pass through the ConnectX-3 to a supported OS to install MLNX_OFED drivers and update firmware etc. On these boxes i get "IOMMU not present". The i5-4590 seems to have Intel VT-d, but i guess my HP Prodesk 600 G1 with it's chipset isn't capable.
All of these 3 machines are running Proxmox 6.x and i'm now planning to install CentOS7 another computer just to flash the cards.
@WANg @arglebargle any idea why the card isn't detected at all by the t730? I obviously have both the standard ConnectX-3 and the Pro VPI (314A-BBCT).
Perhaps cross flashing the cards will help for t730?
EDIT1: Tested with an Intel 350 4 ports device in the PCIe port of t730 and it's detected just fine.
