You need to be careful and do staggered updates in the VMs or it'll spectacularly explode but it's possible and quite performant for less than mission critical VMs.
- tw04 2y agoI think you mean 2TB volume? But yes, this works. But also: if you're doing anything production, I'd strongly recommend doing deduplication on the back-end storage array, not at the NTFS layer. It'll be more performant and almost assuredly have better space savings.
- Joe_Cool 2y agoFor sure it's not for production. At least not for stuff that's critical. MS also doesn't recommend using it for live VHDX. The partition/NTFS volume is 512GB. It currently stores 1.3 TB of "dedupped" data and has about 200GB free. Dedup runs asynchronously in the background and as a job during off hours. It's a typo, yes. Thanks.
