NFS continues to evolve over time. The ONC+ offering that shipped on HP-UX 11i

is a far superior product in terms of functionality, stability, and performance

compared to the ONC+ product that shipped with the HP-UX 11.0 release. This

does not imply that improvements in NFS are only made as new versions of the

operating system are introduced – far from it. HP’s NFS lab continually strives to

improve its products on the existing supported OS releases by distributing patches

containing defect fixes and functionality enhancements.

Since NFS has so many dependencies on other components of the system, it comes

as no surprise that the list of dependent patches is lengthy. It is very important to

keep the patch levels of all the underlying subsystems (i.e. network, buffer cache,

transport, etc.) current since a defect in those subsystems can negatively impact

NFS behavior and performance.
