Data De-Duplication savings with VM/VDI workloads on Windows ‘File’ Server 2012 R2



Some info of my LAB/DEMO environment running Windows Server 2012 R2. These are de-duplication savings from VM workloads delivered by Hyper-V. The environment is up and running for a few years, consisting of around 30+ VM’s. Overall some pretty great results. Volumes with the lowest percentages are storing the greater part of the VM’s. Savings typically are around 55% to 65%.

Data Deduplication is a Role Services which you can install when you are installing File and iSCSI Services in Windows Server 2012.

I enabled the data dedup for VDI feature in Windows Server Manager – File and Storage Manager. To turn it on, select a non system volume destined for VDI or VM workloads, right click and select ‘Configure Data Deduplication…’

That will result in the next screen. Choose the data deduplication (type).

Next, click on ‘Set Deduplication Schedule…’
Configure the schedule so, that it will not impact user experience.

Note: DeDup for VDI  workloads is a feature in Windows Server 2012 R2, only. DeDup for VM/VDI workloads is not available or recommended with the Dedup implementation of’ Server 2012 (non R2). More on Data Dedup in R2:

Windows Server 2012 R2 has another nice feature. Storage Tiering. Didn’t implement this yet since it requires 3 SSD’s and 3 HDD’s at least, for redundancy. More on storage tiering:
