WebbPlease don't use a 2K or 3K for iSCSI data center traffic :) The other problem you'll have on non-data-center class switches (outside of small per-asic shared buffers) is head of line blocking, in which a congested port can affect traffic destined for non-congested interfaces. You want a switch with virtual output queuing to mitigate this behavior.
