Method for system energy use management of current shared power supplies

A power supply system, comprising:

• a plurality of power supplies;
• and
• a system controller, configured to:
• determine a system mode for the power supply system;
• determine an operating order for the plurality of power supplies;
• assign the system mode to each of the plurality of power supplies;
• assign an ACTIVE ON threshold to each of the plurality of power supplies to obtain a plurality of ACTIVE ON thresholds;
• and
• assign an ACTIVE STANDBY OFF threshold to each of the plurality of power supplies to obtain a plurality of ACTIVE STANDBY OFF thresholds,
• wherein the power supply system provides electrical power to a computer system,
• wherein each of the plurality of ACTIVE ON thresholds is distinct, and
• wherein each of the plurality of ACTIVE STANDBY OFF thresholds is distinct.

A system controller for a power supply system, comprising:

• a processor;
• and
• a computer readable medium comprising computer readable program code embodied therein, which when executed by the processor, perform a method, the method comprising:
• identifying a plurality of power supplies included in the power supply system;
• determining a first system mode for the power supply system;
• determining a first operating order for the plurality of power supplies;
• assigning a first ACTIVE ON threshold to each of the plurality of power supplies to obtain a plurality of first ACTIVE ON thresholds;
• and
• assigning a first ACTIVE STANDBY OFF threshold to each of the plurality of power supplies to obtain a plurality of first ACTIVE STANDBY OFF thresholds.
