VCS Simulator is a tool to assist you in building and simulating cluster configurations. With VCS Simulator you can predict service group behavior during cluster or system faults, view state transitions, and designate and fine-tune various configuration parameters. This tool is especially useful when you evaluate complex, multi-node configurations. It is convenient in that you can design a specific configuration without test clusters or changes to existing configurations.
You can also fine-tune values for attributes that govern the rules of failover, such as Load and Capacity in a simulated environment. VCS Simulator enables you to simulate various configurations and provides the information that you need to make the right choices. It also enables simulating global clusters.
