    Mar 01, 2012 · The whole point of thin provisioning, whether done on the array or at the hypervisor layer, is to allow a VM to run with just the storage it needs, and to avoid giving a VM storage that it might use sometime in the future.

Array Thin Provisioning and VMFS Datastores - VMware

    https://docs.vmware.com/en/VMware-vSphere/5.5/com.vmware.vsphere.storage.doc/GUID-08CBB1F0-0CF5-4783-9A12-EB3B5A2BB830.html
    ESXi also supports thin-provisioned LUNs. When a LUN is thin-provisioned, the storage array reports the LUN's logical size, which might be larger than the real physical capacity backing that LUN. A VMFS datastore that you deploy on the thin-provisioned LUN can detect only the logical size of the LUN.
