Abstract: Modular information handling systems supported in a modular chassis, such as blade information handling systems, have power allocation managed by dynamic and automated prioritization of power application to each modular information handling systems. A priority list of modular information handling systems is generated and updated by analysis of priority factors discovered from the modular information handling systems, such as with periodic polling of the modular information handling systems or detection of predetermined events at the information handling systems.

Abstract: Systems and methods for power management in an information handling system are disclosed. A method may include determining a power requirement of resources configured to receive power from a plurality of power supply units including one or more online power supply units, one or more redundant power supply units, and one or more standby power supply units. The method may also include determining a power capacity of the one or more online power supply units. The method may additionally include determining if the power capacity of the one or more online power supply units exceeds the power requirement of the resources. The method may further include transitioning at least one of the power supply units based on such determining steps.

Abstract: Power from a modular chassis to plural modular information handling systems contained by the chassis is dynamically allocated according to power consumed at each modular information handling system and a priority associated with each modular information handling system. A power manager of the modular chassis allocates power by setting a maximum power for each modular information handling system based upon a priority for each modular information handling system. A power monitor on a modular information handling system requests additional power allocation if power consumed is within a predetermined amount of the maximum power for that system. The power manager allocates additional power in response to the request if another modular information handling system has excess power allocated or if the requesting modular information handling system has a higher priority than another modular information handling system.

Abstract: A demand based power re-allocation system includes one or more subsystems to assign a power allocation level to a plurality of servers, wherein the power allocation level is assigned by priority of the server. The system may throttle power for one or more of the plurality of servers approaching the power allocation level, wherein throttling includes limiting performance of a processor, track server power throttling for the plurality of servers. The method compares power throttling for a first server with power throttling for remaining servers in the plurality of servers and adjusts throttling of the plurality of servers, wherein throttled servers receive excess power from unthrottled servers.

Abstract: A modular enclosure including first, second, third, and fourth servers, and a chassis management controller. The first, second, and third servers each have reclaimable power. The fourth server is configured to request a specific amount of power needed to complete a power-on request received at the fourth server. The chassis management controller is in communication with each of the first, second, third, and fourth servers. The chassis management controller is configured to reassign all the reclaimable power of the first server and to reassign a portion of the reclaimable power of the second and third servers to the fourth server.

Abstract: Systems and methods for managing blades in the event of a power supply unit failure are disclosed. A method may include determining whether a reduced power capacity of the non-failed power supply units is sufficient to provide an aggregate minimum power requirement of the resources in response to a failure of a particular power supply unit. The method may also include powering down a low-priority resource and not powering down a second resource having a higher priority than the low-priority resource if the reduced power capacity of the non-failed power supply units is not sufficient to provide the aggregate minimum power requirement of the resources.

Abstract: A power supply unit of an information handling system determines that a power consumption module of the information handling system is available. If the power consumption module is available, the power supply unit measures input power of the power supply unit and provides a representation of the input power to the power consumption module in response to receiving a power measurement request from the power consumption module. If the power supply unit determines that the power consumption module is not available, the power supply unit measures input power of the power supply unit and stores a representation of the input power at the power supply unit independent of a power measurement request from the power consumption module.

Abstract: An information handling system includes a plurality of power supply units (PSUs) to supply power to one or more system components. For each PSU of the plurality of PSUs, a power conversion efficiency profile for the PSU is determined using a power management control module of the information handling system. The power conversion efficiency profile represents a power conversion efficiency of the PSU for each of one or more power outputs capable of being supplied by the PSU. The power management control module determines a total amount of power to be supplied to a load of the information handling system, and engages a select number of PSUs to provide the total amount of power based on the total amount of power and the power conversion efficiency profiles of the PSUs.

Abstract: Infrastructure power resources of a chassis information handling system are made available to run chassis information handling system modules when infrastructure devices are not using the power resources. For example, cooling fans that cool information handling system modules supported by an information handling system chassis run at variable speeds having variable power consumption. A power reserve maintained to run the cooling fans at full speed if needed is made available to information handling system modules when under power management by a chassis manager.

Abstract: A method for maintaining a continuous authenticated session in an information handling system including first and second chassis management controllers (CMCs) is provided. The first CMC receives user authentication information from a user, authenticates the user for a communication session based on the received user authentication information, generates session information regarding the communication session based at least on the received user authentication information, and stores the session information in memory accessible to the second CMC. Upon a failover from the first CMC to the second CMC, the second CMC automatically accesses the session information from the memory and uses the accessed session information to continue the communication session.

Abstract: An information handling system having plural processing modules, such as an information handling system blade chassis having plural information handling system blades, allocates power by determining an actual load sharing power loss associated with plural power supplies and applying the actual load sharing power loss to determine how much power to allocate to the information handling system modules. A chassis manager determines actual load sharing power loss by retrieving power information from plural power supplies. The actual load sharing power loss replaces a worst-case load sharing power loss assumed value to increase the amount power available for allocation to the information handling system modules.
