CISCO UCS, ESXi 4.1 and Microsoft Clustering

Hi,

We have an environment which include the following infrastructure:

1 x Cisco UCS Chassis with 16 B200 M2 UCS Blades

1 x NetApp 3140 with FCP licenses and 4 FCP ports

16 x ESXi Hosts

I would like to deploy a virtual Microsoft Cluster, does the UCS use RAW Fibre Channel or is all traffic sent over FCoE and if that it the case, is this a supported configuration on ESXi with Cisco UCS?

Thanks,

Mitch
