Figure 1: This shows preliminary results from testing from Sunday Nov 6. The summary is that simultaneous iperf is good from all hosts (9.9+ Gbps) . Reading from disk and writing memory is reasonable with performance of 7.5 -8.5 Gbit/s, but I think could do with some improvement. Disk to disk performance is only 5.0 Gbps and not really adequate for the test. We are using 2000 atlas files of around 500MB on each node for the transfers. We had better performance with 10G files written with 'dd'. Graph pulled from
cacti for the Brocade
