摘要： A data center energy management (DCEM) server configures a power supply in the data center. The DCEM server sums input alternating current (AC) power of the power supply to a total AC power of the data center, wherein the total AC power of the data center is a sum of AC power of a plurality of power supplies. The DCEM server sums output direct current (DC) power of the power supply to a total DC power of the data center and reports a ratio of total AC power to total DC power as data center power conversion efficiency. The DCEM server sets a preset power supply efficiency threshold. The DCEM server determines that a real-time power efficiency level is below the power supply efficiency threshold. The DCEM server, responsive to a determination that real-time power efficiency level is below the power supply efficiency threshold, may remedy the power supply.

摘要： A sensor array including multiple current sensors provides input for power measurement and management systems. The sensor array includes split ferrite cylinder portions connected by a frame, so that when the array is installed around multiple branch circuits in a power distribution panel or raceway, the ferrite cylinders are completed to surround the conductor(s) of the associated branch circuit. Voltage sensing may also be incorporated within the sensors by providing an electrically conductive plate, wire or other element that capacitively couples to the corresponding wire(s).

摘要： A mechanism is provided for statistical determination of power circuit connectivity based on signal detection in a circuit. Signal data from the circuit gathered and a determination is made as to whether a signal of interest is present in the gathered signal data from the circuit using a statistical analysis of the gathered signal data. The statistical analysis comprises using a mean current value and statistical deviation of the current value of the signal data over a predetermined period of time to compute a confidence range. The confidence range is compared to a first threshold and a second threshold. A determination is made that the signal is present in response to the confidence range being above the first threshold. A determination is made that the signal is not present in response to the confidence range being below the second threshold.

摘要： Dynamically allocating cache in a multi-tenant infrastructure includes monitoring cache usage for multiple workloads in a multi-tenant processing infrastructure to determine a workload phase. A baseline performance level per workload is determined. The baseline performance level is dependent upon the workload phase. The workloads for each tenant are categorized based on cache utilization and the cache is allocated to each workload based on the baseline performance level, cache utilization, and system wide cache capacity.

摘要： A clamping current and voltage sensor provides an isolated and convenient technique for measuring current passing through a conductor such as an AC branch circuit wire, as well as providing an indication of an electrostatic potential on the wire, which can be used to indicate the phase of the voltage on the wire, and optionally a magnitude of the voltage. The device includes a body formed from two handle portions that contain the current and voltage sensors within an aperture at the distal end, which may be a ferrite cylinder with a hall effect sensor disposed in a gap along the circumference to measure current, or alternatively a winding provided through the cylinder along its axis and a capacitive plate or wire disposed adjacent to, or within, the ferrite cylinder to provide the indication of the voltage. When the handles are compressed the aperture is opened to permit insertion of a wire for measurement.
