Did you get these fully working? I'm actually trying to get them to work right with Proxmox 4 (Debian 8.2).
I could never get native 10gigE mode to work correctly on the ConnectX-1 cards.
I guess mlx4_en driver is broken or 1st gen ConnectX support was removed as these were EOL-ed long time ago.
The two ConnectX-1 cards worked OK in IPoIB mode but that had a number of issues for me:
- Can't connect to a 10gigE switch (the whole point of getting these cards)
- Couldn't show iface bandwidth stats
- Have to run OpenSM on one of the nodes
So I gave up on that idea.
