More of an FYI than anything else, I recently found out that 10Gb interfaces will not work on R71 VE running on ESX 4.1. I opened a case with support after I couldn't get the VM to see the 10Gb NIC. Even using the "flexible" driver instead of the e1000, it only sees 1Gb.

BTW, the NIC I am using is on the HCL.
Intel Ethernet Server Adapter X520 Series

I had to have our local SE submit a request for enhancement.

Anyone else run into similar issues? Or come up with a "non-standard" workaround?
