Preface

Sun^TM Cluster Concepts Guide for Solaris OS contains conceptual and reference information for the SunPlex^TM system on both SPARC® and x86 based systems.

Note –

In this document, the term “x86” refers to the Intel 32-bit family of microprocessor chips and compatible microprocessor chips made by AMD.

The SunPlex system includes all hardware and software components that make up Sun's cluster solution.

This document is intended for experienced system administrators who are trained on Sun Cluster software. Do not use this document as a planning or presales guide. You should have already determined your system requirements and purchased the appropriate equipment and software before reading this document.

To understand the concepts described in this book, you should have knowledge of the Solaris^TM Operating System and expertise with volume manager software used with the Sun Cluster system.

Note –

Sun Cluster software runs on two platforms, SPARC and x86. The information in this document pertains to both platforms unless otherwise specified in a special chapter, section, note, bulleted item, figure, table, or example.
