Abstract
Systems and methods are disclosed that may be used for controlling information handling system power supply based on current system power policy such as current system load power need and/or based on current system load power capping information. The disclosed systems and methods may be so implemented to improve power use efficiency for information handling system applications in which a power supply unit (PSU) has a power delivery capability that is overprovisioned relative to the power-consuming system load component/s of an information handling system.
Claims20
An information handling system, comprising:
- one or more power-consuming components that together constitute a system load;
- at least one power supply unit (PSU) coupled to supply power to the system load, the PSU being configured to supply power to the system load using two or more available non-zero PSU operational power modes that each have a different respective deliverable power range;
- and
- at least one processing device configured to:
- determine a current power policy for the system load, the current power policy specifying a current power policy power level for the system load that corresponds to at least one of a total maximum possible power consumption level of the currently installed power-consuming components of the system load, a power-capped total power consumption level of the power-consuming components of the system load, or a combination thereof,
- select a first one of the PSU operational power modes of the at least one PSU based on the determined current power policy for the system load, and
- cause the PSU to supply power to the system load using the selected first one of the PSU operational power modes.
A method for powering an information handling system, comprising:
- providing one or more power-consuming components that together constitute a system load for the information handling system;
- providing at least one power supply unit (PSU) coupled to supply power to the system load, the PSU being configured to supply power to the system load using two or more available non-zero PSU operational power modes that each have a different respective deliverable power range;
- and
- using the at least one processing device to:
- determine a current power policy for the system load, the current power policy specifying a current power policy power level for the system load that corresponds to at least one of a total maximum possible power consumption level of the currently installed power-consuming components of the system load, a power-capped total power consumption level of the power-consuming components of the system load, or a combination thereof,
- select a first one of the PSU operational power modes of the at least one PSU based on the determined current power policy for the system load, and
- cause the PSU to supply power to the system load using the selected first one of the PSU operational power modes.
