Perform the following procedure to determine which resources in your Capacity Planner capacity model are under-utilized. For information about how to move an under-utilized resource, see How to Add Capacity by Reallocating Resources.
Once you have identified resources that have little or not utilization, you can move server roles from an under-utilized device and then reallocate the unused resource.
To identify under-utilized resources
In Simulation Results, on the Servers pages look for low utilization percentage to determine which resource is under-utilized.
Click the Utilization column heading to sort the results.
Click the Device column click the list arrow, and then click a device type to filter the results for the device type.
Identify the devices and servers that have little or no utilization.
