What about the case of iWARP <-> IB ?
Crossing IB shouldn't matter. iWarp should simply cross the IB subnet
using IPoIB. You could build a gateway to make the transfer across IB
more efficient, but it's not required.
I don't understand this statement. iWARP is RDMA based and if someone
I was referring to the case where both endpoints are running over iWarp, with IB
being one of the subnets being crossed. I believe that you're referring to one
side running over iWarp, and the other running over IB, with an application
level gateway in between.
For the latter case, I would think that the gateway needs to establish iWarp
connections for any IP addresses that reside on the IB subnet behind it, with a
separate IB connection on the back-end. It seems to me that this would occur
transparently to the application using iWarp.
