Hy, FYI 70MB/s is the theoretical limit of a single 1GB isci connexion, if you want more, then you should consider using NIC aggregation.
Oracle can perform well on iscsi, it depends only of the bandwith you have, try to aggregate your 2 NIC's and use iozone to make some bench :) hoping this helps, Rachid On Fri, Jul 03, 2009 at 11:53:07AM +0100, Nick Lunt wrote: > > I'm running Oracle 10g on RHEL5, using Equallogic iSCSI SAN.
