The Data Center Operation: Energy Cost module provides an Energy Usage Report, which shows energy consumed within the data center by the kWh and cost per kWh, detailed to the rack level. The energy usage is based on metered data, gathered over a specified period of time. If no metered data is available, estimated power draw will be calculated based on the power draw of the individual IT assets or nameplate values. The Energy Usage Report provides the option of including an overhead factor accounting for energy losses through data center (PUE). The report can be customized based on optional groupings by use of tags, such as department, tenant, purpose, density etc.
