Before you can create a failover cluster, you must install the Failover Clustering feature on all servers that you want to include in the cluster. This section provides instructions for installing this feature.

Note that the Failover Clustering feature is included in server products such as Windows Server 2008 R2 Enterprise and Windows Server 2008 R2 Datacenter. The Failover Clustering feature is not included in Windows Server 2008 R2 Standard or Windows Web Server 2008 R2.
