I'm guessing IPoIB clients could work with a RoCE Ceph cluster via an Ethernet/Infiniband gateway (like the Mellanox product), but the IPoIB clients could not do RDMA as this won't cross the gateway(at least I understand this is the case with the Mellanox product). _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
