I read that it's a Voltaire version = and it is the same as Mellanox ConnectX, which supposed to be supported. Yep, they should work. You may need to flash them with their Mellanox = equivalent firmware, but I'm not sure. (doing that flash isn't very hard btw) > Also, most InfiniBand cards provide two ports. When connecting two = computers together (IPoIB) is it possible to use both ports to double = the speed? Not sure, as I've not needed to personally. None of my storage (or = other uses) even fills one DDR port. Yet. :) I *think* the answer to that is yes, > Lastly, is NFS RDMA properly supported on FreeBSD? Again not sure. Other people here would likely know. :) + Justin -- "My grandfather once told me that there are two kinds of people: those who work and those who take the credit.
