Abstract

An information handling system includes a processor, an air moving system, a power system, and power demand reduction circuit. The air moving system is operable to cool the processor. The power system is operable to power the processor and the air moving system. The power demand reduction circuit is operable to detect a total power system power demand that will exceed a power system output capacity of the power system in response to a processor power demand from the processor and, in response, reduce an air moving system power provided to the air moving system such that the processor power demand will no longer cause the total power system power demand to exceed the power system output capacity. The air moving system power may be increased when a decrease in the processor power demand results in the two contributing to a total power system power that will not exceed the power system output capacity.

Claims (38)

1. A power demand reduction system, comprising:

at least one powered component;

an air moving system that is configured to cool the at least one powered component;

a power demand reduction circuit that is coupled to the air moving system and that is configured to couple to a power system including a power supply unit (PSU), wherein the power demand reduction circuit is configured to:

receive a PSU over-current warning signal directly from the PSU, wherein the PSU over-current warning signal indicates that a PSU power demand on the PSU will exceed a power supply output capability of the PSU;

determine that a total power system power demand will exceed a power system output capacity of the power system in response to a powered component power demand from the at least one powered component and the PSU over-current warning signal;

activate a load reduction mechanism in the at least one powered component to reduce a power demand from the at least one powered component;

reduce an air moving system power provided to the air moving system and provide a rotational kinetic energy from the air moving system to the at least one powered component subsequent to reducing the air moving system power such that the powered component power demand from the at least one powered component will no longer cause the total power system power demand to exceed the power system output capacity of the power system; and

determine that a predetermined time period has passed that is required for the load reduction mechanism in the at least one powered component to reduce the power demand from the at least one powered component and, in response, restore the air moving system power provided to the air moving system.

2. The power demand reduction system of claim 1 , wherein the

at least one powered component includes at least one processor.

3. The power demand reduction system of claim 1 , wherein the predetermined time period that is required for the load reduction mechanism in the at least one powered component to reduce the power demand from the at least one powered component is greater than a PSU-related time period that the PSU can endure the PSU power demand that exceeds the power supply output capability of the PSU without shutting down.

4. The power demand reduction system of claim 1 , wherein the reducing the air moving system power provided to the air moving system including completely removing the air moving system power provided to the air moving system.

5. The power demand reduction system of claim 1 , wherein the reducing the air moving system power provided to the air moving system including reducing first air moving system power provided to the air moving system to a second air moving system power that allows the air moving system to operate.

6. An information handling system (IHS), comprising:

a processor;

a memory coupled to the processor;

an air moving system that is configured to cool the processor and the memory;

a power system coupled to the processor, the memory, and the air moving system, wherein the power system includes a power supply unit (PSU); and

a power demand reduction circuit coupled to the air moving system and the power system, wherein the power demand circuit is configured to:

receive a PSU over-current warning signal directly from the PSU, wherein the PSU over-current warning signal indicates that a PSU power demand on the PSU will exceed a power supply output capability of the PSU;

determine that a total power system power demand that will exceed a power system output capacity of the power system in response to a processor power demand from the processor and the PSU over-current warning signal;

activate a load reduction mechanism in the processor to reduce a power demand from the processor;

reduce an air moving system power provided to the air moving system and provide a rotational kinetic energy from the air moving system to the processor subsequent to reducing the air moving system power such that the processor power demand from the processor will no longer cause the total power system power demand to exceed the power system output capacity of the power system; and

determine that a predetermined time period has passed that is required for the load reduction mechanism in the processor to reduce the power demand from the processor and, in response, restore the air moving system power provided to the air moving system.

7. The IHS of claim 6 , wherein the predetermined time period that is required for the load reduction mechanism in the processor to reduce the power demand from the processor is greater than a PSU-related time period that the PSU can endure the PSU power demand that exceeds the power supply output capability of the PSU without shutting down.

8. The IHS of claim 6 , wherein the reducing the air moving system power provided to the air moving system including completely removing the air moving system power provided to the air moving system.

9. The IHS of claim 8 , wherein the reducing the air moving system power provided to the air moving system including reducing first air moving system power provided to the air moving system to a second air moving system power that allows the air moving system to operate.

10. A method for power system power demand reduction, comprising:

monitoring a total power system power demand for a power system having a power system output capacity, wherein the power system includes a power supply unit (PSU);

receiving a PSU over-current warning signal directly from the PSU, wherein the PSU over-current warning signal indicates that a PSU power demand on the PSU will exceed a power supply output capability of the PSU;

determining that the total power system power demand will exceed the power system output capacity of the power system in response to a processor power demand from a processor and the PSU over-current warning signal;

activating a load reduction mechanism in the processor to reduce a power demand from the processor;

reducing an air moving system power provided to an air moving system and providing a rotational kinetic energy from the air moving system to the processor subsequent to reducing the air moving system power such that the processor power demand from the processor will no longer cause the total power system power demand to exceed the power system output capacity of the power system; and

determining that a predetermined time period has passed that is required for the load reduction mechanism in the processor to reduce the power demand from the processor and, in response, restoring the air moving system power provided to the air moving system.

11. The method of claim 10 , wherein the predetermined time period that is required for the load reduction mechanism in the processor to reduce the power demand from the processor is greater than a PSU-related time period that the PSU can endure the PSU power demand that exceeds the power supply output capability of the PSU without shutting down.

12. The method of claim 10 , wherein the reducing the air moving system power provided to the air moving system including completely removing the air moving system power provided to the air moving system.

13. The method of claim 10 , wherein the reducing the air moving system power provided to the air moving system including reducing first air moving system power provided to the air moving system to a second air moving system power that allows the air moving system to operate.
