An information handling system includes multiple power supply units, and first and second chassis management controllers. The power supply units provide power to components within the information handling system. The first chassis management controller calculates a first number of power supply units needed to provide power to the components of the information handling system, and asserts a first chassis armed signal to servers in response to a detection that the first number of power supply units is greater than zero. The second chassis management controller receives the first number of power supply units from the first chassis management controller, and asserts a second chassis armed signal to the servers in response to a detection that the first number of power supply units being greater than zero.

Information handling system having synchronized power loss detection armed state

A method may include monitoring a power capacity of power supply units of a chassis, responsive to determining that the power capacity is lesser than a first minimum power capacity required for full operation of all of the modular information handling systems and information handling resources of the chassis and greater than a threshold power capacity for triggering operation in a minimal operational state of the chassis, causing at least one of the plurality of modular information handling systems and the information handling resources to reduce power consumption, and responsive to determining that the power capacity is lesser than the threshold power capacity and greater than a second minimum power capacity for a minimal operational state of the modular information handling systems and information handling resources, causing at least one of the plurality of modular information handling systems and the information handling resources to operate in the minimal operational state.

System and methods for prioritized multi-node server and infrastructure availability during power capacity loss

A method performed by an information handling system, the method including detecting that a first device has been connected to the information handling system (IHS). The method further including in response to detecting that the first device has been connected, updating one or more fabric consistency validation rules of the IHS associated with the first device and one or more other devices that are connected to the first device by one or more links, and validating that the first device is compatible with each of the other devices based on the updated fabric consistency validation rules of the IHS.

System and method for adaptable fabric consistency validation and issue mitigation in an information handling system

A computer-implemented method dynamically limits peak power consumption in processing nodes of an IHS. A power management micro-controller receives processing node-level power-usage and workload data from several node controllers, including current power consumption and a current workload, for each processing node within the IHS. A total available system power of the IHS is identified including a peak power output capacity and a sustained output power capacity. At least one node peak power threshold is determined based on the power-usage and workload data for each of the processing nodes. The node controllers are triggered to determine and set a device peak power limit for each of several variable performance devices within each of the processing nodes based on the node peak power threshold, wherein each of the variable performance devices dynamically adjusts a value of a corresponding device performance metric based on the device peak power limit.

Dynamic peak power limiting to processing nodes in an information handling system

In accordance with embodiments of the present disclosure, a method may include, during boot of a modular information handling system disposed in a chassis configured to receive a plurality of modular information handling systems and a plurality of modular information handling resources, pausing execution of a basic input/output system. The method may also include communicating a first indicator, wherein the first indicator causes a chassis management controller of the chassis to perform link optimization operations of a communication link between the modular information handling system and a modular information handling resource. The method may further include, in response to communication by the chassis management controller of a second indicator, the second indicator indicating completion of link optimization operations by the chassis management controller, unpausing execution of the basic input/output system.

Systems and methods for in-situ fabric link optimization in a modular information handling system chassis

A first operating condition and a second operating condition at a power supply unit (PSU) are determined at a first time. A power conversion efficiency of the PSU is determined at the first time. A first entry at a power conversion efficiency profile is generated, the first entry associating the first power conversion efficiency with the first operating condition and the second operating condition.

System and method for providing multi-dimensional power supply efficiency profiles

A computer-implemented method dynamically limits peak power consumption in processing nodes of an IHS. A power management micro-controller receives processing node-level power-usage and workload data from several node controllers, including current power consumption and a current workload, for each processing node within the IHS. A total available system power of the IHS is identified including a peak power output capacity and a sustained output power capacity. At least one node peak power threshold is determined based on the power-usage and workload data for each of the processing nodes. The node controllers are triggered to determine and set a central processing unit (CPU) peak power limit for each of several CPUs within each of the processing nodes based on the node peak power threshold, wherein each of the CPUs dynamically adjusts an operating frequency based on the CPU peak power limit.
