vSphere 6.0: NFS 4.1 does not support hardware acceleration. This limitation does not allow you to create thick virtual disks on NFS 4.1 datastores. vSphere 6.5: NFS 4.1 support hardware acceleration and thick virtual disks Source: https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.storage.doc/GUID-8A929FE4-1207-4CC5-A086-7016D73C328F.html https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.storage.doc/GUID-8A929FE4-1207-4CC5-A086-7016D73C328F.html
