Thank you for your response. The SAN is a 10gbe Nimbus with I believe
to be iscsitarget(http://iscsitarget.sourceforge.net/) as it's target
server.
The switch is a Cisco Nexus5010 set to jumbo frame and flow control.
We have through tcp/ip performance tests in conjunction with Cisco
proved that

A note: I don't know how well open-iscsi uses multiple threads, but looking at
individual CPUs may be interesting, as the above is only an average for
