| 摘要 |
Methods, systems, and computer program products are provided for managing computer power consumption in a data center. Embodiments include monitoring aggregate power consumption of a plurality of computers in the data center, each of the computers being supplied power individually from a shared circuit in the data center; determining whether the aggregate power consumption exceeds a predetermined maximum threshold; if the aggregate power consumption exceeds the predetermined maximum threshold, selecting a number of computers for throttling in dependence upon priority; and throttling-down the selected computers, reducing the aggregate power consumption to a level below the predetermined maximum threshold. Some embodiments may also include determining whether the aggregate power consumption is below a predetermined minimum threshold; if the aggregate power consumption is below the predetermined minimum threshold, selecting a number of computers for throttling in dependence upon priority; and throttling-up the selected computers, increasing the aggregate power consumption to a level above the predetermined minimum threshold.
