This is based on deploying a single 64-node failover cluster that uses Windows Server 2012 R2 Hyper-V. Note that individual components such as the Operations Manager can be scaled further to support larger and more complex environments. In these cases, a four-node Fabric Management cluster would be required to support scale.
