Abstract: An example computing system may include computer module bays, a power subsystem to supply power to computer modules installed in the computer module bays, and a system controller. The power subsystem may also implement overcurrent protection (OCP) based on an OCP threshold parameter. The system controller may include dynamic OCP adjustment logic that repeatedly updates the OCP threshold parameter during normal operation of the computing system. The dynamic OCP adjustment logic may update the OCP threshold parameter by determining a power requirement of the computing system based on a current configuration of the computing system, determining a new OCP threshold based on the power requirement, and instructing the power subsystem to change a value of the OCP threshold parameter to a new value based on the new OCP threshold.

Abstract: Examples herein relate to an apparatus. In some examples, an apparatus may include a circuit to direct a power signal to at least one electrical component. The circuit may include a protection device to regulate power to the electrical component, detection circuitry to detect when the protection device has failed, and an alert handling logic to receive a signal from the detection circuitry that the protection device has failed.

Abstract: Examples disclose an electrical connector comprising a first pin and a second pin. Each pin has a different length corresponding to a different data signaling rate.

Abstract: Various embodiments described herein provide for establishing connectivity of nodes by employing base management controllers associated with the nodes. For some embodiments, a first data is received at a resource manager from a first base management controller (BMC) associated with a first node, wherein the resource manager is associated with a server computer system. A second data is received at the resource manager from a second BMC associated with a second node. A classification of the first node and the second node are determined and a compatibility of the first node with the second node based on the first data and the second. A topology is generated, at the resource manager, of the first node and the second node.

Abstract: Embodiments provide methods, apparatuses, and systems for transmitting an auto-negotiation message via one lane of a plurality of lanes to determine a link configuration between a first device and a second device, wherein the link configuration utilizes a plurality of lanes. In response to the auto-negotiation message, the network device may determine that one of the plurality of lanes is inoperative. The network device may then reconfigure the link configuration to utilize a subset of the plurality of lanes.

Abstract: At least one computer system receives power from a power system having a maximum power output based on a nominal power consumption of the at least one computer system. The power system is operable to detect an amount of power consumed by the at least one computer system, and compare the power consumption to a threshold based on the maximum power output of the power supply. The power system is operable to place one or more components of the at least one computer system in a lower-power state to reduce power consumption in response to the amount of power consumed by the at least one computer system exceeding the threshold.

Abstract: A memory subsystem includes multiple memory modules coupled by point-to-point links. A memory controller is coupled by a point-to-point link to a first memory module, which is turn is coupled by another point-to-point link to another memory module. Further memory modules may be coupled by respective point-to-point links in the memory subsystem. In some arrangements, each memory module tracks commands issued to other memory modules, such as more upstream memory modules. Also, in one example implementation, a clock is embedded within a data stream transmitted over a point-to-point link, so that an external clock is not employed in this example implementation.
