Correction: Windows Branch Caching is targeted for the release in 2H'13. 
I've got a VNXe 3300. Does anyone know if CIFS File Shares on the Shared Folder Server support Branch Cache. I've created the shared folder, but don't seem to have an option for Branch Cache
EMC VNXe 3300 - Shared Folder Server (CIFS File Shares) Branch Cache Support?
