debian - IPoIB (IP over InfiniBand) vs. RDMA performance ...

★ ★ ★ ☆ ☆

Since I don't want to run performance tests on a production system I am wondering: Are there published performance comparisons for IPoIB vs. RDMA/InfiniBand. For instance, could I expect bandwidth/latency gains from switching away from IPoIB in the orders of magniute of either 10%, 50%, or 100%, say? What could be expected?

Difference between IPoIB and TCP over Infiniband

★ ★ ☆ ☆ ☆

TCP throughput well over 10 Gb/sec is possible using recent systems, but this will burn a fair amount of CPU. To your question, there is not really a difference between IPoIB and TCP with InfiniBand -- they both refer to using the standard IP stack on top of IB hardware.

IPoIB with Netem (Latency emulation) Poor performance

★ ★ ★ ☆ ☆

I'm not sure if emulating latency on an end system is the right way to go. Latency on a network comes from the propagation time across the medium (5 microseconds per km on optical fiber) and from deep buffers (also see the "buffer bloat problem", you'll find tons of resources about it on the net).

IPoIB is layer 3, not layer 2, so I can't bond it for VMs on the server; Instead, I have to do routing, which adds latency and drops performance (the 6Gb/s) I'm still happy with it. It wouldn't be viable to iSCSI boot Windows or NFS mount my home directory over a 1Gb/s link. I tried it, the performance is abysmal when doing a large number of ...

networking - InfiniBand network performance - Stack Overflow

★ ★ ★ ★ ★

The firmware has a very very small QP cache (of the order of 16 - 32) depending upon which adaptor you are using. When the number of active Qps exceeds this cache, then any benefit of using IB starts to degenerate. From what I know, the performance penalty for a cache miss is of the order of mili seconds.. yes thats right.. milliseconds..

4/6/2005 · These drafts eventually should lead to an RFC standard for IPoIB. IPoIB does not take full advantage of IB's performance, however, as traffic still passes through the IP stack and is sent packet by packet. IPoIB does provide a simple way to run legacy applications or send control traffic over IB.
