Is there anyone out there using a CX4 with FCoE ports?  And if you are would you be willing to share your setup/environment and experience?

In our environment we are running a CX4-480 that is both FC and FCoE attached to 2 Cisco Nexus 5020 switches.  We are also running Dell PowerEdge R710 servers, which have QLogic QLE8152 CNA cards in them.  These servers run VMware ESXi 4.1U1.  When we zone the hosts to the storage over the Clariion's FCoE ports we see a ton of discards and rx pauses on the Nexus ports the Clariion is connected to.  But when we zone the hosts to the Clariion's FC ports we don't have any issues.

We do have a case open with EMC support, as well as VMware, Cisco and QLogic.  I wanted to see if anyone has had similar problems, or has a similar environment.

Thanks,

Don
