We are still running the IOMeter benchmarks using the new ZFSBuild2012 server and InfiniBand SRP. The numbers we are seeing with SRP are absolutely awesome. For example, right now it is running a 32k random read benchmark and it is getting nearly 60,000 IOPS and moving 1854MB/second. This is amazing because when we ran raw IB performance tests on the network, the max performance of the IB network was 1890MB/second. The ib_read_bw and ib_write_bw tools showed our IB network moving an average of 1869MB/second and a peak of 1890MB/second. It is really exciting to see the ZFSBuild2012 box delivering 1854MB/second through IOMeter, which is about 98% of the wirespeed for our IB network.
