Looking around but unable to find any information on leveraging Windows Dedup and compression on a Windows file server VM hosted on VMware 6.7. The data disks I'd like to dedupe and compress are built on an NetApp HCI datastore volume(s). The question I have is if dedup and compression is enabled on the file system of the VM on how it would affected efficiencies on the HCI side of things or if there would be an effect. All disk on the VM are thin provisioned as well. Any thoughts would be great. Thank you

Any dedupe or compression higher in the stack will reduce it further down.
In this case, using dedupe and compression inside the Windows VM will reduce the savings on the HCI storage.
Normally it is better to let the storage handle it, because the system can dedupe across multiple VMs whereas running it inside one VM will only dedupe the data inside that machine.
