DataDomain backup over Fibre Channel??

Hi you all,

Is there any "Guide" or Manual or something in order to achieve to backup data over FC?

We have FC zonning created between DD, Networker Server and Client; DataDomain Fibre enabled and Acces Groups created as well; Networker Server is an MCSCluster, and so is the Client.

We have created a Fibre Device, and are able to "label" devices, but when a backup starts, we see that the client traffic goes throught Ethernet..

Thanks in advance
