Prerequisites
You must have read privilege on the vCenter Server, entity cost modify privilege on the chargeback hierarchical
entities, and update privilege on the cost models to perform this task.
Procedure
1 In the Configure Cost tab, click Edit Infrastructure Cost.
2 Select Hosts & Clusters from the drop-down menu.
3 Expand the Hosts & Clusters folder by clicking the plus sign.
4 Click the plus sign next to Clusters to view the clusters defined in the vCenter Server instances added to
vCenter Chargeback Manager.
To view the ESXi hosts that are not included in any cluster, you can click the plus sign next to Unclustered
Hosts.
5 Select the cluster or an individual ESXI host for which you want to define the rate factors.
If you select a cluster, the right pane of the page displays the cluster properties and the ESXI hosts under
the selected cluster along with the fields to set the rate factors for individual computing resources.
6 Select a cost model from the drop-down menu.
7 Specify the duration for which the rate factors will be effective.
The default selection is Update from now onwards, indicating that the rate factors will be effective from
the time of setting them on the entity till they are modified.
If you want to set the rate factors for a specific duration, select Update for the effective period and specify
the start and end date of the time period. The dates have to be entered in the mm/dd/yyyy format. If the end
time is not specified, the rate factors will be effective till they are modified at a future date. You can view
the existing rate factors for the specified time period by clicking Get Rate Factors.
8 (Optional) Click Show next to Historical values to view the historical base rate and rate factor values of
all the computing resources for the specified time period.
9 Specify the rate factors for the required computing resources and click Update Rate Factors.
10 Click OK in the information dialog box.
Managing Datastore Tiers
vCenter Chargeback Manager lets you define rate factors for individual datastores. You can also create tiers,
add datastores to the tiers, and set rate factors at the tier level.
Setting rate factors at the tier level enables you to apply the same rate factor to multiple datastores. The rate
factors set at the datastore level can be overridden by the rate factors set at the entity level in the chargeback
hierarchy. You can also define rate factors for VM storage profiles defined in the vCenter Server. The rate factor
configured on a storage profile is applied to all the datastores that match the storage profile.
When the storage cost is calculated, vCenter Chargeback Manager checks for the cost configuration on the
datastore. If the datastore matches a profile and in listed under a profile, then the cost configuration on the
profile is considered. If the datastore or the profile is grouped under a tier, then the cost configuration details
of the tier is used for calculating the storage cost.
If a datastore matches more than one profile, then the datastore appears under each matching VM storage
profile. In such a case, the highest user-defined rate factor set on the VM storage profiles is considered.
Therefore, if a datastore matches two different profiles and if you have not defined any rate factor on either of
the profiles, then default rate factor of 1 is considered. If you have defined rate factor on both the profiles, then
the highest of the two rate factors is considered. However, if you have defined rate factor on only one of the
profiles (say, 0.75), then the user-defined rate factor is considered even if it is less than the default value of 1.
