Looks like you are right, some quick tests made on a iscsitarget linux server using nullio and fileio on a sata drive give much better results than the netapp file server with it's 12 disks (and while the netapp is directly connected to the client and on a jumbo frame network, the linux initiator i

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 an

HBA versus software initiator (open-iscsi)

2009-06-04 Thread benoit plessis
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
