I see in several product announcments that the lastest version supports CIFS shares on an EMC celerra, but the documentation list that the primary storage must reside on a Windows Server.

Our primary shares reside on the EMC Celerra (like a giant expensive NAS), we want to enable DFS to move these files to less expensive disk.

Can the latest version support this? I see language about using a "proxy" but its not clear.
