What tests have you or the customer done to confirm that performance
is very very good? A lot of times the system is not as fast as the
customer thinks, it's just faster than it was before and they're
happy. Also, there could be problems in the driver or firmware on
your P400 versus the customer one. I'd look for those differences as
well. I doubt SATA versus SAS is the problem, but who knows...
