Abstract: Systems and methods to identify peer nodes in a multi-node enclosure are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a baseboard management controller (BMC) or a Datacenter-Secure Control Module (DC-SCM); and a memory coupled to or integrated with the BMC or DC-SCM, where the memory includes program instructions stored thereon that, upon execution by the BMC or DC-SCM, cause the IHS to: obtain configuration information associated with a first compute node of a multi-node enclosure; write the configuration information associated with the first compute node to a shared storage device that is accessible to other compute nodes of the multi-node enclosure; and obtain other configuration information associated with one or more other compute nodes of the multi-node enclosure from the shared storage device.

Abstract: Systems and methods support load sharing between multiple power supply units (PSUs). An example, analog control signals used to control the PSUs may generate power outputs from one or more of the PSUs, where the power outputs may be outside of the desired range. Systems and methods may apply a feedback loop to compare power output to analog control signal levels and then to adjust analog control signal levels accordingly.

Abstract: In systems and methods, a power distribution system provides power for multiple chassis installed in a rack. Two or more power supply units (PSUs) are installed in the chassis and may draw power redundantly from separate power grids supplying power to the rack. A first PSU of the chassis is coupled to one power grid and a second PSU of the same chassis is coupled to another power grid. Upon a failure in the second power grid, power drawn from the first power grid by the first PSU is limited according to a first current limit specified in a first emergency rack protection policy of the rack. Upon a failure in the first power grid, power drawn from the second power grid by the second PSU is limited according to a second current limit specified in a second emergency rack protection policy of the rack.

Abstract: A ventilation channel device may be used to provide cooling to components of a computing device. A ventilation channel device may be U-shaped and may be installed within a volume that is physically between fans. The bottom of the U-shaped may include air inlets, and those air inlets may lead to air outlets that are disposed near air intakes of the fans. The U-shape may be hollow from the inlets to the outlets, thereby allowing airflow from the inlets to the outlets. As a result, the air volume, located between the fans, may be moved by flowing through the ventilation channel device.

Abstract: Systems and methods support a server rack mechanically and gather sensor data from the server rack. For instance, the system may include an apparatus having a frame that is configured to add stiffening to a server rack. On the frame may be disposed various sensors and a computing system to measure stress and strain of the server rack as well as any other appropriate characteristic. The frame may include struts having strain gauges therein, where the strain gauges provide a measurement of stress or strain. Various sensor data may be transmitted from the apparatus to a component outside of the apparatus, such as a data center monitoring application.

Abstract: An information handling system includes a management controller that may determine average power consumption of a processor, and determine average power measurement at a power supply unit. If the average power consumption of the processor does not match the average power measurement at the power supply unit, then the system may calibrate the average power consumption of the processor to match the average power measurement at the power supply unit.

Abstract: A number of slots in a chassis of an information handling system and a number of a plurality of sleds to be housed in the chassis may be determined. An airflow for each of the plurality of sleds in each of the plurality of placement configurations may be determined based, at least in part, on the number of slots in the chassis and the number of the plurality of sleds to be housed in the chassis. A recommended placement for each of the sleds may be determined based at least in part on the airflow for each of the plurality of sleds for the plurality of placement configurations. A notification may be generated comprising the recommended placements for each of the plurality of sleds.

Abstract: An information handling system includes a chassis having multiples sleds and an embedded controller. The embedded controller retrieves relative impedances for all of the sleds, and calculates a maximum available airflow for the first sled based the relative impedances of all other sleds. A baseboard management controller (BMC) of a first sled requests a boot operation for the first sled. The BMC collects configuration information for the first sled, and determines an airflow impedance of the first sled based on the configuration information. The BMC provides the airflow impedance and a power allocation request to the embedded controller. The BMC compares the maximum available airflow to a minimum airflow requirement for the first sled. If the maximum available airflow is less than the minimum airflow requirement, the BMC implements power limits for processors in the first sled to prevent overheating of components within the first sled.

Abstract: A physical power supply unit (PSU) may be connected to several load subsystems. A first load subsystem may receive a first portion of a first load power directly from the physical PSU via a main power connector, the main power connector having a power limit less than the first load power. A second load subsystem may receive a second load power directly from the physical PSU to provide a second portion of the first load power to the first load subsystem via a power connection between the second load subsystem and the first load subsystem. A sum of the first portion of the first load power and the second portion of the first load power may be greater than the power limit of the main power connector.

Abstract: A fail-safe power limit (FSPL) can be applied to components that lose communication with a management module (MM) to determine a safe power level at which to operate. The FSPL may be computed by the management module (MM) for the information handling system and distributed to components in the information handling system. By computing a FSPL and transmitting the FSPL to the components, a larger amount of the available power can be used by the components. This allows the components to continue operating at performance levels closer to or equivalent to levels available when the management module (MM) is operating normally. The FSPL may be updated at set times and/or on a periodic schedule such that the FSPL used by the components when communication is lost with the management module (MM) reflects a recent operating state of the components.
