Abstract
A data center may use generators for backup power, where the backup generators are able to serve less than the maximal power load of the data center. The use of generators that can serve less than the maximal power load may be recognized by, and addressed by, the power policy for the data center. When utility power is lost, the power policy manager may detect that the data center is switching to generator power, and may have knowledge of the capacity of those generators. If the capacity is less than the maximal power load of the data center, the power policy manager may shed load by throttling equipment in the data center to lower power levels. The policy may specify which pieces of equipment are to be throttled. When utility power is restored, the throttling of the equipment may be removed by the power policy manager.
