Abstract: A method of providing power to computer systems in a computer data includes receiving high-voltage power from one or more electric utility distribution systems; transforming the high-voltage power to medium-voltage power; and distributing the medium voltage power through a common medium voltage domain that serves a plurality of medium voltage-to-low voltage converters that are located in rows of computer racks in the computer data center.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for monitoring energy consumption. In one aspect, a method includes sending, to a power monitor of a circuit board, requests for power consumption data. The requests are sent periodically based on a reference clock that is located external to the circuit board and that is more accurate than a clock of the power monitor. Each request is for an accumulated amount of power for components of the circuit board. In response to each request, power consumption data is received from the power monitor. The power consumption data specifies the accumulated amount of power for the components of the circuit board since a previous request sent to the circuit board. An amount of energy consumed by the components of the circuit board over a time period is determined based on the received power measurements and the time period.

Abstract: A method for providing electrical power to a computer data center includes generating alternating-current power by a plurality of generators and converting the alternating current power from each of the generators to direct current power; combining the direct current power from each of the generators into a common electrical domain; and supplying the computer data center using the combined direct current power.
