About This Manual

The Prestoserve product is a combination of the Prestoserve NVRAM hardware and the Prestoserve software. Prestoserve speeds up synchronous disk writes, including NFS server access, by reducing the amount of disk I/O.

This manual describes how to install, configure, and use the Prestoserve software on systems that have the Prestoserve hardware installed.

Audience

This manual is written for the person who manages and maintains the Tru64TM UNIX® (formerly known as DIGITAL UNIX) operating system. The manual assumes that this individual is familiar with Tru64 UNIX commands, the system configuration, and the system hardware.

Organization

This manual consists of four chapters:

Chapter 1 Provides an overview of disk operations, the Network File System (NFS), and Prestoserve.
