Pro-Rata Power Budgeting
11 Using OpenManage Enterprise Power Manager for Chargeback
4 Pro-Rata Power Budgeting
An organization consists of multiple sub-organizations, and power costs are generally divided equally as part
of the operating income. For example, there is a sub-organization SO-A, and SO-B. If SO-A consumes 90%
of the power and SO-B consumes only 10%, you cannot bill them equally when they have consumed different
amount of power. Hence, both the sub-organizations must be billed based on the amount of power consumed
by them respectively.
This results in an imbalance in the budgeting. For example, a certain organization such as the IT might
always consume more power compared to the Finance organization, but since the power bill is equally
divided, the actual operating income per sub-organization level is never truly known. Power Manager helps
you create an effective and transparent power budgeting system.
4.1 Implementation
You can consider each of the sub-organization at a cost-center level as a group in OpenManage Enterprise.
Each of these groups have a certain set of devices for which they are billed pro-rata wise. To differentiate
between devices of different sub-organizations, create separate groups for each sub-organization and keep
the devices in their respective groups. Using Power Manager run the Power and thermal report to evaluate
the power and energy consumption during a phase (each billing cycle—one month).
