FcOE IBM N 6040 (FAS3140)

Has anyone any experience of using native FCoE with this system - We are exploring a green field solution using end-to-end FCoE, see below:

IBM x3850 X5

Qlogic CNAs

VMware vSphere

Cisco Nexus 5010

IBM N 6040

Has anyone done this, tested this? - What was your experience, should we consider it or should we look at FC at the array with FCoE from the switch to the ESX servers?

One other thing, I has read somewhere that you need to use the Nexus 1000v on your ESX servers to support FCoE over CNAs - Is this correct?
