Abstract: A power system is coupled to a powered system and a system capacitance. The power system includes a power system output sensor, a power conversion device, and a power system output controller. The power system output controller includes a powered system threshold that is related to a power excursion capability of the powered system. The power system output controller is operable, in response to receiving a power system output signal from the power system output sensor that exceeds the powered system threshold, to control the power conversion device to increase the power system output from the power conversion device in order to increase the energy stored in the system capacitance for use by the powered system during a power excursion. The powered system may include processors that draw power from the system capacitance during power excursions so as to not exceed the limits of the power system.

Abstract: A supplemental power system includes a powered component, a removable module interface with a plurality of pins, and a plurality of system connections. A system controller detects a first type removable module coupled to the removable module interface and allows signals from the system connections to be transmitted to the first type removable module through the plurality of pins. The system controller detects a second type removable module coupled to the removable module interface and allows power from the second type removable module that is received through the plurality of pins to be transmitted to the powered component while not allowing signals from the system connections to be transmitted to the second type removable module through the plurality of pins. Power that is stored in the second type removable module may be provided to the powered component in response to a detected power excursion by the powered component.

Abstract: A method of power flow mapping in a datacenter includes encoding, by a power supply unit of the datacenter, identification information that uniquely identifies the power supply unit, and modulating the encoded identification information onto a power cable, wherein the power supply unit receives operating power via the power cable. Modulating the encoded information onto the power cable further includes changing a voltage internal to the power supply unit to create a current change in the power cable.

Abstract: An information handling system power supply dynamically adapts thermal and power output protection constraints based upon thermal and power output conditions measured at the power supply. In the event of changing conditions at the information handling system, such as an increase in ambient temperature or an increase in power consumption, a power constraint adaptive module adjusts constraints at which the power supply will shut down in order to maintain power to an information handling system outside of a normal power and thermal constraint operating envelope for the power supply.

Abstract: A power management control system for an information handling system is disclosed. The power management control system includes a power management interface bus interfacing a plurality of devices, where one or more of the devices is each associated with a time clock. The power management control system further includes a management agent interfacing the power management interface bus. The management agent is configured to: receive a system time; synchronize the one or more time clocks based, at least in part, on the system time; and maintain synchronization of the one or more time clocks, at least in part, via a set of telemetric primitives.

Abstract: A method, system, and information handling system provides better system power consumption of a redundant power system having a plurality of power supply units (PSUs) by taking into consideration each PSU's sleep power consumption during selection of one or more PSUs to place into a “hot spare” sleep mode. For each PSU, power efficiency data at different load ratings are measured and stored. During the PSU selection, a calculation of system power consumption is conducted on each of several configurations where a different PSU is hypothetically disabled. Each calculation takes into consideration both the sleep power consumption of a disabled PSU and power efficiency data of an enabled PSU. Selection of one or more PSUs to disable is determined according to the configuration yielding the lower or lowest system input power consumption based on the results of the calculations.

Abstract: A supplemental power system for IHS power excursions includes a processor and a memory coupled to the processor. A power system is coupled to the processor and a plurality of power supply paths. A first power supply path is operable to supply power at a first voltage from the power system to the processor. A second power supply path is operable to store power from the power system at a second voltage that is greater than the first voltage, and the second power supply path is further operable to supply the power stored at the second voltage to the processor during power excursions by the processor. In some embodiments, the second power supply path may include a boost converter to increase power at the first voltage to the second voltage, or may receive power output at the second voltage from a supplemental power rail in the power system.
