Why each option
vSphere 6 supports NFS version 3 and NFS version 4.1; NFS 3.1 is not a real protocol version and NFS 4.0 is explicitly not supported by vSphere.
NFS version 3 has been supported since early vSphere releases, providing standard NAS datastore connectivity for ESXi hosts without additional security or authentication requirements.
NFS 3.1 does not exist as a standardized protocol version; the NFS specification progresses directly from version 3 to version 4.
NFS version 4.0 is not supported in vSphere 6; VMware implemented version 4.1 directly, bypassing 4.0, because 4.1 provides the session and security features required for enterprise storage environments.
NFS version 4.1 was introduced in vSphere 6.0 and adds support for Kerberos security profiles (krb5, krb5i, krb5p) and session trunking for improved resilience on NFS datastores.
