Introduction

A Dell™ Failover Cluster combines specific hardware and software components to provide enhanced availability for applications and services that run on your cluster. A Failover Cluster reduces 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 servers, storage power supplies, connections between the nodes and the storage array(s), connections to client systems or other servers in a multi-tier enterprise application architecture in your cluster.

This document provides information and specific configuration tasks that enable you to configure your Failover Cluster with DellEMC AX4-5i Internet Small Computer System Interface (iSCSI) storage array(s).

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 Failover Cluster, see the Dell Cluster Configuration Support Matrices located on the Dell High Availability Clustering website at www.dell.com/ha.
