One great feature in Windows Server 2012 R2 and above Hyper-V and the file services
is that data deduplication is supported for virtual machines that are used in a VDI
scenario. Remember that the free Microsoft Hyper-V Server is a great solution in VDI
scenarios, because the included Windows Server guest OS licenses with Windows
Server Standard and Datacenter are not required, so using the free Microsoft Hyper-V
Server makes great sense.
Even though the VDI collection automatically uses differencing disks for each VM
instance in the collection to save space, the use of data deduplication will further save
disk space. Some guidelines will say not to use differencing disks at all and instead
rely entirely on data deduplication. Note that while data duplication is supported for
VDI environments only, it is not blocked for other purposes. You should be careful if
you decide to use data deduplication for other workloads because some workloads
may not behave as expected if deduplicated.
