But it looks good on paper, so it's definitely a try worth.
is at least 4x times faster than 10gbe and AFAIK should have a lower latency.
I'm planning to use infiniband as backend storage network, used for
OSD replication. 2 HBA for each OSD should give me 80Gbps and full
redundancy
I haven't done much with IPoIB (just RDMA), but my understanding is that
it tends to top out at like 15Gb/s. Some others on this mailing list
can probably speak more authoritatively. Even with RDMA you are going
to top out at around 3.1-3.2GB/s.
