Hello,
I am planning to use RDMA over IP with Lustre, can someone please let me know what are the
configuration / settings we need to do for Lustre with RDMA over IP? Also, if there is any
list of RDMA supporting cards which are certified with Lustre.
I looked in to the manual and it mentions RDMA with Infiniband, I hope we should be able
to use RDMA with IP as well on Lustre, please reply.
Thanks,
-Upanshu

I'm assuming you mean RDMA over Converged Ethernet? The o2ib driver should
operate via the OFED RoCE layer.

There isn't any support for RDMA over IP. There is RDMA with OFED, which
works IB and iWARP (which is RDMA over ethernet).
If you are referencing some other RDMA-over-IP protocol, then it likely
will not work without the development of a new LND driver. That wouldn't
be a bad thing, if it improved performance or reduced overhead for general
usage, and could e.g. be routed or similar.
