<p>Infiniband shall give lower latency & CPU utilization and
better real-world throughput, so that's probably better Lnet-wise.</p>
<p>But Infiniband gears are more expensive so if taking budget into
account, 100G Ethernet may work good-enough allowing saved cost be
used to upgrade other parts of the system.</p>

With the growth of 100G ethernet, is it better to connect a
lustre file server via EDR 100G Infiniband or 100G Ethernet for
a 32 node HPC cluster running a typical life sciences - Genomics
workload?
