Product Description

This book is a comprehensive guide to understanding how the various components of the NFS product family work together on HP-UX systems and how to configure each of them for optimal performance. 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 to every flavor of Unix, as well as non-Unix based operating systems. Currently, there is very little information available that describes how to tune NFS for performance. What little information that is available always seems to concentrate on the NFS server, all but ignoring the NFS client. More specifically, there are no books available that describe HP's implementation of NFS in any way. The storage market is shifting focus from directly attached storage to a network attached storage model. This book contains dozens of previously undocumented tuning tips and provides detailed instructions for troubleshooting each NFS client and server component.

From the Back Cover

The only authoritative, systematic guide to NFS performance optimization on HP-UX systems.

In Optimizing NFS Performance, one of HP's leading NFS experts presents systematic techniques for optimizing NFS performance on any HP-UX 11 and 11i system in any network and application environment. Dave Olker reviews every component of the NFS product family, showing how they interact on HP-UX systems and how to troubleshoot each element for optimal performance. Olker presents dozens of previously undocumented tuning tips, plus powerful new NFS client optimization techniques that will be invaluable to companies implementing NFS in their environment. Coverage includes:

• Environmental considerations: network, local filesystems, hostname resolution and patch levels
• User-space daemons and kernel threads
• Key decisions and tradeoffs: Automount vs. AutoFS, NFS/UDP or NFS/TCP, NFS/PV2 or NFS/PV3
• CacheFS: potential benefits, limitations, HP-specific enhancements, and measurement techniques
• NFS mount options and recommendations
• Buffer cache sizing techniques that can dramatically enhance performance
• Kernel parameters that significantly influence NFS performance

The only NFS book to focus entirely on HP-UX, Optimizing NFS Performance will be indispensable to every HP-UX system administrator running NFS—or planning to do so.
