[OpenIndiana-discuss] Mellanox MHQH29C-XTR Infiniband HCA compatibility

[Wesley Brown]

Ken,

MCX3 cards can be gotten for $25-$50, and the switch can be gotten for a ballpark of $100-$200.  These cards are primarily for me to test the Infiniband stack with OpenIndiana as part of the verification and test process in my home office lab.

I do agree that in a production sense, that it is better to get the more recent cards such as the MHQH29C-XTR for 40gbps of throughput.   This is the sort of network that we are building, and is why I have one on hand temporarily for my home office.

It has been a frustrating process, as there is no one guide to Infiniband on Solaris -- partially because Oracle rearranged the old Sun support and document sites so many sources of information no longer exist.

I answer this question because I was attempting to research this very subject, and found a scarcity of information on this.

I have a ConnectX based card the works fine with the hermon driver in oi_148, but I have been unable to find any information about Solaris or OpenIndiana support for any of the ConnectX 2 HCAs. I was hoping someone might be using the card (or any of the other PCI device ID 26428 cards  http://www.mellanox.com/content/pages.php?pg=firmware_table_ConnectX2IB
