Using VCS Simulator

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 evaluating complex, multi-node configurations. It is convenient in that you can design a specific configuration without test clusters or changes to existing configurations.

With VCS Simulator, you can predict how VCS behaves in response to resource and system failures in configurations with several groups, resources, and dependencies without affecting your production systems. You can also fine-tune values for attributes governing 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 you need to make the right choices. It also enables simulating global clusters.
