When I got my hands on a Nutanix running VMware I was interested how we could get maximum storage space efficiency out of that. Since Nutanix presents NFS share to ESXi hosts the datastore level reclaim will not be needed. This left me with in-guest reclamation. Used User Space : 26% (it was 46% before the reclaim) Reserved User Space : 4.7Tb/10Tb (did not change unfortunately) However, in VMware, the space didn't change.
