A custom profile defines a specific configuration of an object instance. With profiles, you can determine how many instances of that object can fit in your environment, depending on the capacity remaining and the configuration of that object instance.
To determine how many instances of the object can fit in your environment, use custom profiles with projects and scenarios. Enter the profile numbers or pre-populate the values from specific VMs. Depending on the available capacity in your environment, you can add one or more instances of the object that the custom profile capacity requirements represent.
To determine how many instances of the custom profile object you can include on the parent object, you select the parent object and the Capacity tab. The custom profiles appear on the VM remaining section and indicate how many instances of the object fit in your environment.
