Hi Jonathan, Short answer: no.
We have a cluster which is mixed infiniband (with RDMA) and plain ethernet. You can pick with: mmchconfig verbsRdma=enable -N nodes,... depending if RDMA is on or off by default.

If you wanted to used RDMA with GPFS does every node need to be using RDMA or could it be that just a subset use RDMA? Obviously the nodes with actual storage attached need to be running RDMA, but would I need to upgrade things like protocol or GUI nodes etc. to use RDMA as well? JAB. -- Jonathan A.
