Hi Everyone, I am trying to setup a small size iscsi based storage. Total 16 spindles in a system, connected to two Solaris 10 hosts through intel gig nics. The disks are configured in a mirror, and locally they perform OK. When I try to export them through COMSTAR to those Solaris 10 hosts, unfortunately, the performance tanks. I can only get around 70 to 80 MB/s. all the nics running iscsi traffic are connected to the same unmanaged switch.
I have read about link aggregation. Do you think adding a quad port intel NIC and a managed switch can help in getting higher speed over iscsi. I also read that having a single connection to the target will always use only one of the linked nics, not more than one, so one will stay limited to 1 gb throughput only. Right now, I have 4 connections per target. do you think link aggregation will spread these 4 connections over the 4 nics and give me higher throughput. I am not looking for exact 4 gb wire speeds, but still something better than 1 gb. Also, do i really need a managed switch to connect these or can this be done through a direct cross cable connection? thank you in advance. d.y _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
