Abstract: A system may implement a method for analyzing group level power supply unit efficiency based on information about power supply units (PSUs) that supply power to servers in a server group, and loads in the system. A group level PSU efficiency analyzer may collect PSU related information from respective management controllers on the servers, including PSU capacity, type, or vendor, efficiency tables, load information, or the current efficiency of each PSU (compared to the peak efficiency for the PSU). The analyzer may calculate the group level PSU efficiency by averaging the PSU efficiencies of the member PSUs or by calculating an average of the PSU efficiencies that is weighted based on load. The analyzer may identify changes to the system configuration (e.g., swapping the PSUs that power some servers) that would increase or maximize the group level PSU efficiency using, for example, a graph search or tree search.

Abstract: An information handling system (IHS) includes functional components that are housed within a chassis and interconnected in a configuration of one or more servers to operate as a fully functional IHS. An infrastructure system includes a power throttle module to limit power usage by the functional components and/or a fan module to cool the functional components. An access controller is provided in communication with a sensor which dynamically receives data related to a thermal load that is created by the functional components. A management controller responds to the data being available by controlling the infrastructure system to operate at a level that corresponds to the thermal load indicated by the data. In response to going offline, the management controller controls the infrastructure system to operate at an upper level that corresponds to an estimated thermal load predicated on an in-system power characterization of the configuration of the functional computer components.

A blade history table may be searched for an entry matching or otherwise corresponding to the server blade. If the blade history table includes a matching entry, comprising an entry corresponding to the modular information handling system, the chassis management controller may control the power-on sequence for the server blade in accordance with one or more attributes or fields of the matching entry.
