The technology is generally directed to a management framework that uses a predictive feedback control loop to reduce energy consumption of a datacenter. The framework determines how to place a series of jobs or workloads on the available pool of machines in a datacenter. For example, the framework may consider the current workload profile and the workload demand forecast of the datacenter to determine an updated workload profile. The updated workload profile may include a redistribution of the workloads or jobs onto a first subset of the machines such that a second subset of the machines can enter an idle state.

Efficient datacenter energy management based on compute capacity and fleet management

An energy system may include data center computer equipment, a data center power system configured to simultaneously provide power for operation of the data center equipment and power for cooling the data center equipment, fuel cells configured to provide power to the data center power system, an on-site battery storage configured to provide backup power and power conditioning to the fuel cells, an on-site hydrogen storage to provide fuel to the fuel cells, and an excess heat recovery connection configured to transfer a liquid from the data center power system to provide cooling to the fuel cells.

A data center power system includes an electrical power conductor that includes a live conductor surface and is configured to carry electrical power from a power source through a human-occupiable workspace of a data center. The live conductor surface includes a rail configured to mount to a floor of the data center. The data power system further includes a grounded conductor positioned in the human-occupiable workspace apart from the electrical power conductor; a first electrical connector configured to mount to a data center rack that supports a plurality of electronic devices and moveable to electrically contact the live conductor surface of the electrical power conductor; and a second electrical conductor positioned on the rack and configured to electrically contact the grounded conductor.

Powering electronic devices in a data center

A data center power system includes an electrical power conductor that includes a live conductor surface and is configured to carry direct current (DC) power from a power source through a human-occupiable workspace of a data center; a grounded conductor positioned in the human-occupiable workspace apart from the electrical power conductor; a first electrical connector configured to mount to a data center rack that supports a plurality of electronic devices, the first electrical connector moveable to electrically contact the live conductor surface of the electrical power conductor; and a second electrical conductor positioned on the rack and configured to electrically contact the grounded conductor.

This specification describes a power distribution system comprising a first section that receives power from a first source. The power at the first section is adjusted by a rectifier coupled to a power bus of the first section. The system includes a second section that is separate from the first section and that receives power from a second source. The power at the second section is adjusted by a rectifier coupled to a power bus of the second distribution section. The system includes a swing rectifier connected to each of the first and second sections. The swing rectifier is configured to provide power to the first power bus and to the second power bus and to dynamically adjust the power capacity of the first section that is available to computing loads, and to dynamically adjust the power capacity of the second section that is available to computing loads.
