This topic provides an overview of the Failover Clustering feature in Windows Server 2012 R2 Preview and Windows Server 2012. Failover clusters provide high availability and scalability to many server workloads. These include server applications such as Microsoft Exchange Server, Hyper-V, Microsoft SQL Server, and file servers. The server applications can run on physical servers or virtual machines. This topic describes the Failover Clustering feature and provides links to additional guidance about creating, configuring, and managing failover clusters that can scale to 64 physical nodes and to 8,000 virtual machines.
