Hi, Well the target are NetApp Filers, one FAS2020 and the other a FAS3020.
The test system is directly attached to the filer, using either a bnx2 card or an intel The latency is calculated by bonnie++ 1.95 on a ext2 file system, the bandwith came from interface monitoring using cacti or bmon and also bonnie++ Iperf give 924Mbits/sec using iperf Using a 4k dd read on a nfs file mounted on the same filer i got 96Mo/s using an un-optimized path (no jumbo frame, going thru a few switchs and a router) Device blocksize is 4k, as is the FS blocksize 2009/6/4 Pasi Kärkkäinen <pa...@iki.fi> > > On Thu, Jun 04, 2009 at 04:03:28PM +0200, benoit plessis wrote: > > Hi, > > > > What do you think of (real) iSCSI HBA like Qlogic cards under linux ? > > We are using open-iscsi now with bnx2 cards and the perfs are far from > > decent (top 50/100Mbps), > > some comparative tests on an intel e1000 card show betters results > > (500/600Mbps) but > > far from gigabit saturation, and still high latency. > > > > What target are you using?
