Utility aware uninterruptible power supplies for computing facilities

摘要

The present principles are directed to utility aware uninterruptible power supplies. A method includes evaluating services, including service combinations, from among a set of services provided by a computing facility operating under an energy constraint, to select a subset of services to power down or maintain powered so as to maximize a total utility value of the computing facility while operating under the energy constraint. The method further includes powering down, or maintaining power to, the selected subset of services.

1. A method, comprising:
evaluating services by a processor of a computing facility operating under an energy constraint associated with a power disruption, including service combinations, from among a set of two or more services provided by the computing facility, including calculating an optimal service mix for service combinations to select a subset of services, each service having a respective utility value and a respective fixed power consumption, and powering down, or maintaining power to, the selected subset of services, while operating under the energy constraint, so as to maximize a total utility value of the computing facility; wherein the total utility value is determined based on:
the respective utility value for each of the services in the subset,a probability distribution of a length of power disrupting events, anda time window, the time window commencing at a start time of the power disruption and ceasing at an estimated end time associated with the power disruption.
