Cluster Configuration Guide

(see

Versions

at the end of this document)

Introduction

This document defines the supported HP NetServer LP2000r configurations using the HP Rack Storage/12FC

and Microsoft

Cluster Server and one or two HP Rack Storage/12s. These configurations minimize single

points of failure (SPOF, SPOFless

1

) and provide extended availability.

The specific configuration certified and

supported by both Hewlett-Packard and Microsoft

is defined, as are other guidelines to assist you in

configuring your clustered NetServers.

This guide is prescriptive; it describes the configurations supported by

HP.

Any deviance to these configurations can result in an inoperative cluster or an operating cluster with

degraded performance, hidden SPOFs, etc., and therefore will not be supported by HP.
