A power management system includes a power infrastructure having power infrastructure components that couple computing devices to power source(s), and a power management subsystem coupled to the computing devices. The power management subsystem identifies power requirement information for each of the computing devices and power transmission limitation information for the power infrastructure components, and determines a power infrastructure architecture that identifies how the power infrastructure components couple the computing devices to the power source(s). The power management subsystem then uses the power requirement information, the power transmission limitation information, and the power infrastructure architecture to generate and provide a respective input current limit to each of the computing devices. Each respective input current limit is configured to maximize performance of the respective computing device for which it was generated while ensuring availability of the power infrastructure in the event of an unavailability of a subset of the power infrastructure components.

Power management system

Optimized bus powered peripheral battery charging includes a circuit to initiate a change in an advanced configuration and power interface (ACPI) state in a controller allowing charging of a peripheral device battery, the circuit including a signal converter coupled between an input port and the controller to sense when a the peripheral device battery is coupled to an input port and to restrict the controller from changing ACPI state multiple times for a given peripheral device battery coupling; and a ground loop detector coupled in parallel to the signal converter between the input port and the controller to allow the controller to know that the peripheral device battery has maintained being coupled to the input port.

Device charging system

Methods and systems for thermal management are disclosed. The thermal management method and systems may reduce the likelihood of a data processing system exceeding thermal limits even in cases of highly customizable and modifiable data processing system. To reduce the likelihood of the data processing system failing to meet thermal limits, the data processing system may implement a distributed thermal management system. The distributed thermal management system may include multiple components that are responsible for granular and/or global thermal management of the data processing system.

System and method for thermal management of multi-enclosure system

An information handling system includes a management controller that may determine average power consumption of a processor, and determine average power measurement at a power supply unit. If the average power consumption of the processor does not match the average power measurement at the power supply unit, then the system may calibrate the average power consumption of the processor to match the average power measurement at the power supply unit.

Calibrating processor system power consumption

A number of slots in a chassis of an information handling system and a number of a plurality of sleds to be housed in the chassis may be determined. An airflow for each of the plurality of sleds in each of the plurality of placement configurations may be determined based, at least in part, on the number of slots in the chassis and the number of the plurality of sleds to be housed in the chassis. A recommended placement for each of the sleds may be determined based at least in part on the airflow for each of the plurality of sleds for the plurality of placement configurations. A notification may be generated comprising the recommended placements for each of the plurality of sleds.

Chassis layout monitoring and analysis to enhance temperature management

Methods and systems for power management are disclosed. The disclosed methods and system for power management may reduce the likelihood of a data processing system failing to meet power budget or other types of goals regarding power consumption, use, and/or provisioning. To reduce the likelihood of the data processing system failing to meet power related goals, the data processing system may include two power managers. An integrated power manager may manage power consumption based on a current-based, fast changing representation of the quantity of power being supplied by the power supplies. In contrast, a system power manager may manage power consumption based on digital representations of the power supplied by the power supplies, which may refresh the digital representations less quickly than the rate at which the analog current based representation is refreshed.

System and method for power consumption management

An information handling system includes a chassis having multiples sleds and an embedded controller. The embedded controller retrieves relative impedances for all of the sleds, and calculates a maximum available airflow for the first sled based the relative impedances of all other sleds. A baseboard management controller (BMC) of a first sled requests a boot operation for the first sled. The BMC collects configuration information for the first sled, and determines an airflow impedance of the first sled based on the configuration information. The BMC provides the airflow impedance and a power allocation request to the embedded controller. The BMC compares the maximum available airflow to a minimum airflow requirement for the first sled. If the maximum available airflow is less than the minimum airflow requirement, the BMC implements power limits for processors in the first sled to prevent overheating of components within the first sled.

Slot airflow based on a configuration of the chassis

Methods and systems for power management are disclosed. The disclosed power management method and systems may improve the likelihood of data processing systems providing desired computer implemented services while meeting power budget goals and/or other types of goals regarding power consumption, use, and/or provisioning. To improve the likelihood of the power budgets being met, the system may dynamically update power allocations to various components of data processing systems. The power allocations may be dynamically allocated by predicting how changes in existing power allocations may impact the ability of the data processing system to service power allocation requests. If it appears that changes in one or more existing power allocations may allow a power allocation request to be serviced, then the power allocations may be dynamically reallocated to free allocable power. The freed allocable power may be used to service the power allocation.

Method for dynamic feature enablement based on power budgeting forecasting

A physical power supply unit (PSU) may be connected to several load subsystems. A first load subsystem may receive a first portion of a first load power directly from the physical PSU via a main power connector, the main power connector having a power limit less than the first load power. A second load subsystem may receive a second load power directly from the physical PSU to provide a second portion of the first load power to the first load subsystem via a power connection between the second load subsystem and the first load subsystem. A sum of the first portion of the first load power and the second portion of the first load power may be greater than the power limit of the main power connector.

System and method for the redirection of trapped power in a shared infrastructure environment

A fail-safe power limit (FSPL) can be applied to components that lose communication with a management module (MM) to determine a safe power level at which to operate. The FSPL may be computed by the management module (MM) for the information handling system and distributed to components in the information handling system. By computing a FSPL and transmitting the FSPL to the components, a larger amount of the available power can be used by the components. This allows the components to continue operating at performance levels closer to or equivalent to levels available when the management module (MM) is operating normally. The FSPL may be updated at set times and/or on a periodic schedule such that the FSPL used by the components when communication is lost with the management module (MM) reflects a recent operating state of the components.
