Preparing Your Systems for Clustering 37NOTE: For Windows Server 2008 Failover Clusters, you can also use theCluster Validation Wizard.12 Configure highly-available applications and services on your failovercluster. Depending on your configuration, this may also require providingadditional LUNs to the cluster or creating new cluster resource groups.Test the failover capabilities of the new resources.13 Configure client systems to access the highly available applications andservices that are hosted on your failover cluster.Installation OverviewEach node in your Dell Windows Server failover cluster must have the samerelease, edition, service pack, and processor architecture of the WindowsServer operating system installed. For example, all nodes in your cluster maybe configured with Windows Server 2003 R2, Enterprise x64 Edition. If theoperating system varies among nodes, it is not possible to configure a failovercluster successfully. It is recommended to establish server roles prior toconfiguring a failover cluster, depending on the operating system configuredon your cluster.For a list of Dell PowerEdge Servers, Fibre Channel HBAs and switches, andrecommended list of operating system variants, specific driver and firmwarerevisions, see the Cluster Configuration Support Matrices located on DellHigh Availablity Cluster website at dell.com/ha.For more information on deploying your cluster with Windows Server 2003operating systems, see the Dell Failover Clusters with Microsoft WindowsServer 2003 Installation and Troubleshooting Guide.
