You can charge for any disks that are included in the VM template (from which the workload template is created). For example, if the VM template includes three disks, you can charge for one, two, or all three of them.

In addition to the disks included in the VM template, you can add 10 more disks to a workload template and designate them as mandatory or optional. Mandatory disks are always created with the workload. Optional disks are created only if the user selects them. For each disk you add, you can choose whether or not to charge for it.
