Ok, how about this:

The biggest isssue with the "asymmetric" model is that it is NOT "asymmetric"
when there is only 1 TCP connection.  When there is only one connection, it is
the "symmetric" model - I have to do both commands and data on the same
connection.  Then, when there is more than one TCP connection, I switch over to

a different behavior.  Does the "asymmetric" model mandate more than 1
connection? (maybe it should)

The whole purpose of having multiple TCP connections was to enable some kind of

"data stripping".  If there are only two links, and one is "low bandwidth",
then effectively only one is being used. I suppose that if there are "n"
physical links between an initiator/target, that "n+1" TCP connections could be

established, with the extra 1 running on one of the connections to transport
the commands.
