Since he needs 1000ms response on storage isn't ethernet the better option? It can reach 400gb/s on fastest hardware now. I thought Infiniband was only reasonable to use when machines need to quickly access other machines primary memory. I would like to know if I'm wrong about this though.

Agreed and at this point with ROCE there's little reason to go with infiniband given you can find fast ethernet hardware that'll go toe to toe with infiniband on latency and throughput.
