TUNING
In addition to balancing the resources of existing servers, you can create phantom servers to use for future planning. Each phantom server represents a new server that can be loaded with databases. Then you can evaluate the effect of adding a new server before you incur the expense of additional hardware.
The role you assign to a server affects the resource-balancing results.
