Abstract: A cooling system for a server includes at least one liquid cooling unit. The liquid cooling unit connects to the server to provide fault-tolerant cooling to the server when a cooling system connected to the server fails.

Abstract: A power throttling method and system for a memory controller in a computer system comprising a power supply module including a plurality of bulk power supplies (“BPSs”) are described. In one embodiment, each of the at BPSs provides to a power output monitor a status signal indicative of a status thereof. Responsive to receipt of the status signals, the power output monitor determines whether a bulk power supply capacity is below system power requirements. Responsive to a positive determination, the power output monitor drives a throttle control signal to the memory controller to a level indicative of an over-threshold state.

Abstract: Systems, methods, and apparatus are disclosed for supplying power to racks having plural servers. One exemplary embodiment is a system with a rack having a plurality of servers and being connected to two separate alternating current (AC) power grids that distribute power to the plurality of servers with load of the rack being distributed across both AC power grids.

Abstract: A system comprises a first equipment rack, a power distribution unit (PDU) and a plurality of rack connectors. The PDU is mounted in the first equipment rack and is configured to provide alternating current (AC) power that comprises a plurality of phases. The plurality of rack connectors mount within the first equipment rack, and each of the plurality of rack connectors couples to the PDU and provides access to the plurality of phases. Each rack connector is usable to accommodate a first device installed in the equipment rack that uses one or more of the plurality of phases, and is also usable to accommodate a second device installed in the equipment rack that uses one or more of the plurality of phases, thereby permitting each rack connector to couple to any of a plurality of devices, and permitting each of the plurality of devices to use any number of the plurality of phases. The number of phases used by the first device differs from the number of phases used by the second device.

Abstract: A system includes a converter to convert an input voltage to an output voltage, where the converter has an adjustment input. The system further includes a voltage adjustment logic to receive an indication of an electrical current consumed by a load, with the voltage adjustment logic being responsive to the indication of the consumed electrical current to provide a control indication to the adjustment input of the converter to adjust the output voltage from the converter.

Abstract: Systems, methodologies, media, and other embodiments associated with power management are described. One exemplary system embodiment includes an uninterrupted power supply (UPS) manager logic configured to determine a power status of one or more UPS devices attached to one or more external peripheral devices. The UPS manager logic can be configured to notify an appropriate operating system of a power loss to a selected external device.

Abstract: Systems, methodologies, media, and other embodiments associated with detecting and responding to a degradation of a direct current provided to a frequency scalable processor are described. One exemplary frequency scalable processor includes a voltage regulating logic configured to request that a direct current having a reference voltage be provided to the processor. The example processor may also include a logic for detecting whether the voltage matches the reference voltage to within a desired tolerance and to selectively store processor state and/or data based on the detecting.

Abstract: Methodology, systems, and media associated with sensing a magnetic field produced by an electrical signal flowing through a conductor are described. One exemplary system may include a connector that conveys the electrical signal between conductors and an in-line field sensor positioned and configured to sense the magnetic field produced by the electrical signal without affecting the electrical signal.

Abstract: The present invention determines temperature and current from resistance measurements of a single magnetoresistive sensor. A dual-purpose sensor includes the magnetoresistive sensor having a single pair of terminals. The sensor is multiplexed under separate current conditions to produce both a temperature measurement and a current measurement in a vicinity of the sensor. A sensor system includes the dual-purpose sensor, a resistance sensing subsystem and a controller that controls the current conditions. A method of measuring temperature and current includes measuring a first resistance of the dual-purpose sensor while a first current is flowing in a conductor adjacent to the sensor, and measuring a second resistance of the sensor while a second current is flowing in the conductor. The first current has a known value while the second current has an unknown value. The temperature and current are determined respectively from the first and second resistance measurements.
