NFS and Hardware Acceleration

Virtual disks created on NFS datastores are thin-provisioned by default. To be able to create thick-provisioned virtual disks, you must use hardware acceleration that supports the Reserve Space operation.

NFS 3 and NFS 4.1 support hardware acceleration that allows your host to integrate with NAS devices and use several hardware operations that NAS storage provides. For more information, see Hardware Acceleration on NAS Devices.
