We have been using 10g CX4 for the past 7yrs for our cluster core network and are just going fully into 10gT. But our focus is more on bandwidth/HTC instead of HPC, i.e. we do not care so much about latencies. Do you have any particular tests in mind, we can certainly look into it and report back on our findings.
