When you say disk performance, I would assume this local disk. If you're referring to remote LUN performance that's a different story. Since you're talking about swapping the CNA I take it you're referencing an FC Storage LUN - correct?
Can you give more specifics on the performance #'s you're seeing? Some benchmarks would really help.
Swapping the VIC for the 2nd Gen Qlogic CNA is only giving you a faster FC ASIC (8Gb/s vs. 4Gb/s on the VIC). This wouldn't account for your issue as you say there's a difference between bare metal and Hypervisors when using the VIC...
