Configure Chargeback for Storage Tiers

Chargeback for storage tiers lets you charge different rates for each tier on physical systems and virtual machines (Hyper-V and VMware).

Storage tiers are classifications for the data stores associated with each disk. Tiers generally indicate different levels of performance of the data store on which a VM and its hard drives are created. Administrators can enable or disable storage tiers.

When the administrator enables storage tiers, users can select them when they make virtual machine reservations. See Allow Users to Select Storage Tiers.

When assigning chargeback rates, keep in mind that the charge is for 24 hours a day and 7 days a week during the reservation period. Enter realistic hourly rates and surcharge amounts based on factors like energy costs and hardware maintenance expense. Most rates will probably range from 10 cents to 50 cents an hour.

Note: Chargeback is optional. The default rates are 0 (no chargeback).
