iSCSI: Number of commands

No - see the SAM-2 discussion of tagged command queuing.
At any instant in time, only one command can be in the process
of being received from a connection, but that has to do with
TCP and the laws of physics.  Many commands from a connection
can be queued for execution by SCSI or actually being executed
at the same time.

That's correct, aside from the "a non immediate command" words.

Please use a subject line that includes "iSCSI" for this sort
of question in the future.
