use Jumbo frames and thruput might be much better. Then again I don't know
how iSCSI generates packets. I hope it's not 1 packet per disk block which
is typically 512bytes. presumably how many disk blocks / packet is a
(auto-)tunable parameter.

switch price matters. But some of the cheepies claim features that the
big-names charge 10x as much for which doesn't make sense. I never pay the
Cisco tax unless there is a gun to my head.
