EMC has announced support for the Server Message Block (SMB) 3.0 as a default CIFS protocol in their VNX and VNXe product line series storage products. SMB is developed by Microsoft and version 3.0 was introduced with the release of Windows Server 2012 and Windows 8. The protocol is used to access file shares over the network capable of providing increased performance, scalability, and continuous availability.
Therefore the protocol is now used in a scenario where Hyper-V virtual machines are stored on a remote file share accessed through SMB 3.0. In this case storage provided by the EMC VNX and VNXe products as detailed in this paper: EMC VNX and VNXe with Microsoft SMB 3.0.
The EMC storage products also support Offload Data Copy (ODX) providing offloading for storage within the same box.
