With the new Windows Server 2012 there are several improvements in the storage part, expecially when we apply to a Hyper-V enviroment.

The main news on the storage part, is that now is possible build a Windows Fail-Over Cluster with a shared SMB3 share and use it for store VMs (in a similar way as NFS could be use to NAS connectivity on a VMware vSphere cluster). Also a specific function (Virtual Fibre Channel) as been added to map a FC SAN LUN directly to a VM (similar to the same function in VMware vSphere).

The different scenarios are now changed from the Pre-2012 (on the left) and the new 2012 version (on the right):

The new CSV2 could also be used with SMB3 to build a Scale Out FileServer (SOFS) and implement an active-active clustered fileserver that could also scale-in by adding more disks and/or bays. But note that the shared enabled for applications (like Hyper-V or SQL Server 2012) have some limits (for example DFS could not be used with FRS to replicate the share content on two or more modes).
