•Allocationunits:
Although the Allocation Pool and Reservation Pool examples dier as to the percentage of guaranteed
resources, the two vDCs are sized identically to the end user and vCenter Chargeback Manager. Without
overage enabled, the allocation units for the two vDCs are the same.
After vCenter Chargeback Manager has allocation units populated for vCloud entities, cost calculations can be
performed through the use of cost models, billing policies and fixed costs.
