Why each option
Data ONTAP 8.1 Cluster-Mode supports NFSv3, NFSv4.0, and NFSv4.1 as its three supported NFS protocol versions for NAS client connectivity.
NFSv.0 is not a valid or ratified NFS protocol version and has never been implemented as an industry standard.
NFSv1 was an early internal Sun Microsystems prototype that was never publicly released or standardized for external use.
NFSv1.1 is not a recognized or ratified NFS protocol version in any IETF standard.
NFSv3 is a widely supported baseline NFS protocol version that Data ONTAP 8.1 Cluster-Mode supports, providing stateless file access for NAS clients.
NFSv4.0 introduced stateful operations and stronger security, and is supported in Data ONTAP 8.1 Cluster-Mode as a standard NFS protocol option.
NFSv4.1 support, including parallel NFS (pNFS) capabilities, was introduced in Data ONTAP 8.1 Cluster-Mode, making it a key differentiating feature of that release.
NFSv5 does not exist as a ratified IETF NFS protocol standard and is not supported by any production storage platform.
