Hi All,

The reason we selection loaner machines (UNH provided) for the development
was to avoid interference with the existing setup, i.e. don't break or
degrade the performance tuned systems.

For the deployed testing (i.e. once we have the OVS developed and
integrated with the lab dashboard) can be done either on the existing
hardware, or a stand alone setup with multiple NICs.  I think this was
proposed, because function testing with multiple NICs would had more
hardware coverage than the two vendor performance systems right now.  That
might also be a lower bar for some hardware vendors to only provide a NIC,

In we choose the "option A" to use the existing performance setups, we
would serialize the testing, so the performance jobs run independently, but
I don't think that was really the question.
