I have 2 6509's with SupII's installed that have a GigE trunk link between them. We noticed ISCSI traffic taxing the CPU on the SUP when ISCSI traffic was traversing the Gig link. We are upgrading to Sup 720's soon and I'm hoping this situation should be resolved. Has anyone seen the performance on ISCSI traffic traversing Gig trunk links on a Sup 720?
