Hi, While openvswitch does not support InfiniBand natively, it is still possible to use IB features. One can create GRE tunnels with endpoints on IPoverIB interface.
Recently I've come to an idea to use RDMA for tunneling packets between hypervisors. Since all tunnels are point to point, one can create new port with type, say, "rdma", provide connection parameters, like local/remote verbs and so on. From now on, packets that sent to this ports will be transferred to remote via RDMA. I have found sample kernel module that does rdma transfer of a memory region between two nodes. I've also looked into openvswitch sources and think that this feature could be implemented without redisign. Are you interested in that functionality? If yes, I can start working on that. I have text editor, compiler and InfiniBand fabric available for testing. -- Regards, -- Sir Raorn. --- http://thousandsofhate.blogspot.com/
