Framework for managing PSU maximum power consumption threshold via management controller

A method comprising, in an information handling system that includes a host system including at least one processor and a memory, a management controller configured to provide out-of-band management of the information handling system, and a power supply unit (PSU):

• the management controller determining a PSU throttle cap (PTC) value for the PSU, wherein the PTC value represents a maximum amount of power to be supplied by the PSU, and wherein the PTC is based at least in part on an inventory of information handling resources of the information handling system and further based at least in part on workload information obtained from an operating system (OS) of the host system;
• and
• in response to power utilization of the information handling system equaling or exceeding the PTC value, the management controller causing the information handling system to be throttled to reduce the power utilization.

An article of manufacture comprising a non-transitory, computer-readable medium having computer-executable instructions thereon that are executable by a management controller of an information handling system that includes a host system including at least one processor and a memory, a management controller configured to provide out-of-band management of the information handling system, and a power supply unit (PSU), the instructions being executable for:

• determining a PSU throttle cap (PTC) value for the PSU, wherein the PTC value represents a maximum amount of power to be supplied by the PSU, and wherein the PTC is based at least in part on an inventory of information handling resources of the information handling system and further based at least in part on workload information obtained from an operating system (OS) of the host system;
• and
• in response to power utilization of the information handling system equaling or exceeding the PTC value, causing the information handling system to be throttled to reduce the power utilization.
