Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method that budgets power allocation for an information handling system (IHS) includes: in response to determining that the IHS is to be powered by a redundant configuration of PSUs, budgeting a first amount of power that is less than a maximum power that can be utilized by the system, and configuring the system to autonomously utilize unused operating margin of the secondary PSU(s) in a redundant configuration of the PSUs during periods in which the system requires greater than the first amount of power; and in response to the information handling system not being powered by a redundant configuration of multiple PSUs, budgeting a second amount of power for the system that is at least equal to the maximum power that can be utilized by the system and is within the output of the primary PSU.

Abstract: A power controller of an information handling system (IHS) controls power allocation for the IHS with components that intermittently exhibit power transients. The power controller is configured to: identify an enhanced power state during which a maximum power required by the information handling system is greater than the amount of power provided by a primary PSU of a redundant configuration of PSUs; and allocate a portion of the unused operating margin of backup reserve power from the redundant PSUs to support intermittent power transients that occur during enhanced power state operation. The power controller is further configured to, in response to a detection of a condition that reduces an amount of unused operating margin of backup reserve power to less than an amount of additional power required to support the intermittent power transients, autonomously disable/limit the enhanced power state to prevent/limit an occurrence or magnitude of the intermittent power transients.
