A typical VCS cluster configuration in a physical environment involves two or more physical machines.
The application binaries are installed on a local or shared storage and the data files should be installed on a shared storage. The VCS agents monitor the application components and services, and the storage and network components that the application uses.
During a fault, the VCS storage agents fail over the storage to a new system. The VCS network agents bring the network components online and the application-specific agents then start application services on the new system.
