Abstract
A system and method for controlling power consumption is described herein. A computer system includes an enclosure. The enclosure is configured to contain a plurality of removable compute nodes. The enclosure includes a power controller configured to individually control an amount of power consumed by each of the plurality of removable compute nodes. The power controller provides a plurality of power control signals. Each power control signal is provided to and controls the power consumption of one of the plurality of removable compute nodes.
Claims15
A computer system, comprising:
- an enclosure having a plurality of removable compute nodes and a centralized power controller configured to individually control an amount of power consumed by each of the plurality of removable compute nodes;
- wherein the centralized power controller provides a plurality of power control signals, each power control signal provided to and controlling, based on a duty cycle of the power control signal, the power consumption of one of the plurality of removable compute nodes, and wherein each power control signal connects to a power control input of the respective compute node, and wherein each power control signal is removably connected to the respective compute node.
A method, comprising:
- measuring, by a centralized power controller, an amount of power being consumed by each of a plurality of removable compute nodes installed in an enclosure of a computer system;
- determining, by the centralized power controller, whether a total amount of power being consumed in the enclosure exceeds a predetermined limit;
- and
- reducing, by the centralized power controller, power consumption of at least one of the plurality of compute nodes based on the determination of total power being consumed by changing a duty cycle of at least one of a plurality of power control signals provided by the centralized power controller, wherein each power control signal connects to a power control input of one of the compute nodes, and wherein each power control signal is removably connected to the respective compute node.
A centralized power controller in an enclosure of a computer system, the centralized power controller comprising:
- circuitry configured to individually measure the power consumed by each of a plurality of compute nodes removable installed in the enclosure;
- and
- a software system that when executed causes a processor of the centralized power controller to limit an amount of power consumed by at least one of the plurality of compute nodes;
- wherein the centralized power controller provides a plurality of power control signals, each power control signal provided to and controlling, based on a duty cycle of the power control signal, the power consumption of one of the plurality of removable compute nodes, wherein each power control signal connects to a power control input of the respective compute node and, wherein each power control signal is removably connected to the respective compute node.
