Dell talks about multiple vmkernel ports per NIC because that way they get to utilize all of the eth-interfaces of the Equallogic arrays. Each separate iSCSI session from each vmkernel port will get redirected to the 'best' interface in the Equallogic group (of possibly many arrays).

If you're doing random IO then you're not limited by the gigabit ethernet interface speed, but disk/spindle speeds and controllers.
