An information handling system has a regulator, a power indication network, a PSU, and a BMC. The regulator receives a system power level indication and provides power to a processor based upon the power indication. The power indication network includes a first resistor stage to shunt the power indication to a ground plane, and a second resistor stage selectably to shunt the power indication to the ground plane. The PSU provides the power indication as a current output where a level of current output indicates a power level provided by the PSU. The BMC determines a power budget for the information handling system, calculates a number of resistor stages to couple to the ground plane based on the power budget, when the number is less than or equal to one, selects the second resistor stage to be uncoupled from the ground plane, and when the number is greater than one, to select the second resistor stage to be coupled to the ground plane.

Dynamic PSys resistor network for improved accuracy and reduced transients

An information handling system includes a power supply unit, a processor, and a baseboard management controller. The power supply unit includes a first energy counter configured to store first power level information associated with an amount of power supplied by the power supply unit. The processor includes a second energy counter configured to store second power level information associated with an amount of power consumed by the processor. The baseboard management controller periodically calibrates the second power level to the first power level based upon a variable calibration cycle time.

Maximizing system power calibration algorithm accuracy

An information handling system polls telemetry data from sensors associated with a central processing unit, and determines current offsets for each one of the sensors based on the telemetry data. The system may also determine a domain current offset associated with a calibration domain, determine a voltage regulator offset based on the domain current offset, and adjust power provided by the voltage regulator to the central processing unit based on the voltage regulator offset.

Adaptive current offset calibration adjustment

Disclosed methods for managing two or more information handling systems receive administrator preferences for a job to be scheduled ton each system and assign time slots, based on the administrator preferences, for performing the job on each system. The time slots are assigned in a manner that avoids or minimizes time slot overlap. Job requests are created for each system wherein each job request includes or otherwise indicates a scheduled time slot for executing the job.

Systems and methods for asynchronous job scheduling among a plurality of managed information handling systems

An information handling system may include at least one information handling resource and a power management subsystem configured to: receive signals from a plurality of power supply units, each signal indicative of an environmental parameter associated with a respective power supply of the plurality of power supply units; determine, for each of the plurality of power supply units, a respective environmental effective power capacity based on the respective signal indicative of the environmental parameter for such power supply unit and an environmental profile for such power supply unit; and manage power consumption of the at least one information handling resource based on environmental effective power capacities of the plurality of power supply units.

Systems and methods for minimizing system hardware throttling due to power supply unit environmental effective capacity

An information handling system may include a power system comprising a plurality of power supply units and a management controller communicatively coupled to the plurality of power supply units. The management controller may be configured to monitor real-time direct current (DC) power consumption by components of the information handling system, determine an effective output capacity of each of the plurality of power supply units, and based on the real-time DC power consumption and effective output capacity of each of the plurality of power supply units, determine a real-time power supply unit workload attribute that indicates a number of the plurality of power supply units required to provide the real-time DC power consumption.

Systems and methods for determining real-time workload power supply units and enhanced redundancy reporting

A system may include a plurality of power supply units and a management device communicatively coupled to the plurality of power supply units and configured to determine a minimum number of power supplies required to support a maximum peak power budget for components of the system, determine a minimum number of power supplies required to support a minimum peak power budget for components of the system, and reduce a throttle threshold of a number of healthy power supplies of the system at which a fast throttling of the components of the system will occur if the minimum number of power supplies required to support the maximum peak power budget is equal to the minimum number of power supplies required to support the minimum peak power budget.

Systems and methods for optimizing fault tolerant redundancy for an information handling system with multiple power supply units

A chassis includes power supply units configured to be a primary source of power for several information handling systems. A chassis management controller monitors a power capacity of the power supply units, and sends a measure of first available power of the power supply units to one of the information handling systems. If the power limit of a sled connector is at least equal to the first power requirement of the information handling system, then it may be determined whether a total power available for the information handling system is at least equal to the first power requirement of the one information handling system. If the total power available for the information handling system is at least equal to the first power requirement of the information handling system, then the information handling system may be powered on.

System and method for increasing power delivery to information handling systems

A method may include, in a host information handling system configured to be inserted into a chassis providing a common hardware infrastructure to a plurality of modular information handling systems including the information handling system: (i) determining a runtime health status of a persistent memory subsystem of the host information handling system; and (ii) communicating a health status indicator indicative of the runtime health status to a management module configured to manage the common hardware infrastructure.

Systems and methods for prevention of data loss in a power-compromised persistent memory equipped host information handling system during a power loss event

Systems and methods for reduced boot power consumption using early BIOS controlled CPU power states to enhance power budgeting and allocation. An information handling system may include a server. The server may include a central processing unit (CPU), a memory, a non-volatile random-access memory (NVRAM) device, a performance state (P-state) limiting indicator stored in the NVRAM device, a P-state value stored in the NVRAM, and a basic input/output system (BIOS) stored in the memory. The BIOS may read a power state limiting indicator stored in the NVRAM device and when the power state limiting indicator indicates that power state limiting is enabled, read a power state value stored in the NVRAM, and program the power state of the CPU to the power state value to cause the CPU to limit power supplied to the CPU to the power state value.
