Introducing Network File System Version 4 on HP-UX 11i v3

Conclusion
The Network File System (NFS) has existed in one version or another since 1985. NFSv4 marks a big
departure from previous NFS protocol versions because it introduces state into the NFS protocol and
folds ancillary mechanisms such as ACLs, file locking, and mounting, into the core protocol. In
addition, NFSv4 improves Microsoft Windows interoperability with an enhanced attributes
mechanism, share locks, ACL support, and stronger security. Using this latest NFS protocol version
provides high reliability and improved performance, as well as complete interoperability with systems
that implement previous NFS protocol versions only.
With ONCplus version B.11.31.03, the introduction of features such as cross mounts, referrals, and
delegation stackable module for local access provides a more complete NFSv4 offering on HP-UX 11i
v3.
