Networked File System (NFS) has been the industry standard protocol for remote
file access on the UNIX operating system platform for many years. It has become a
critical component of every flavor of UNIX, as well as many non-UNIX based
operating systems. NFS is also a central component of HP’s NAS offerings.
However, there is very little information available describing how to properly tune
NFS clients and servers for optimal performance.
HP recently released HP-UX version 11i to support our new SuperDome hardware
platform. Many changes were made to our NFS offering in this version of HP-UX;
however, some of these differences are not currently described in any customer-
viewable documentation. Also, there are no books available that specifically
describe HP's NFS implementation.
The target audience for this presentation is systems, network, and storage
administrators who want to learn how to optimally configure their HP-UX clients and
servers for NFS performance. Some familiarity with the basic concepts of NFS and
HP-UX internals are assumed.
