To expand on that slightly, this also includes (to add to the acronym
soup) RoCE - RDMA over Converged Ethernet - in other words using
Ethernet networks (with appropriate switches) to do the sort of RDMA
that you can do over Infiniband.

This is important as unlike Infiniband you can't do RoCE out of the box
with something like RHEL7 (at least in the experience of the folks I'm
helping out here).
