Introduction

A Dell™ Failover Cluster combines specific hardware and software
components to provide enhanced availability for applications and services
that are run on the cluster. A Failover Cluster is designed to reduce the
possibility of any single point of failure within the system that can cause the
clustered applications or services to become unavailable. It is recommended
that you use redundant components like server and storage power supplies,
connections between the nodes and the storage array(s), and connections to
client systems or other servers in a multi-tier enterprise application
architecture in your cluster.

This document provides information to configure your Dell|EMC CX3-series
fibre channel storage array with one or more Failover Clusters. It provides
specific configuration tasks that enable you to deploy the shared storage for
your cluster.

For more information on deploying your cluster with Windows Server 2003
operating systems, see the

Dell Failover Clusters with Microsoft Windows

Server 2003 Installation and Troubleshooting Guide

located on the Dell

Support website at

support.dell.com

. For more information on deploying

your cluster with Windows Server 2008 operating systems, see the

Dell Failover Clusters with Microsoft Windows Server 2008 Installation and
Troubleshooting Guide

located on the Dell Support website at

support.dell.com

.

For a list of recommended operating systems, hardware components, and
driver or firmware versions for your Dell Failover Cluster, see the
