Abstract: The present disclosure relates to the estimating of data cooling specific to the individual location of the data centers by re-rating the performance rating of the modular cooling units. By analyzing data center specific metrics, the performance of the modular cooling units may be adjusted to account for changes in weather conditions, fan coil performance, hydraulic capacity, cold aisle temperatures, etc. All data may be provided to the user to allow for more efficient data cooling, predictions based on weather changes, and real time adjustments.

Abstract: The present disclosure provides for dynamically deactivating rectifiers to force remaining rectifiers to operate at or near their peak power efficiency. Rectifiers, for example rectifiers on racks of a data center, may operate according to an efficiency curve, based on its current load. Instead of distributing an AC power load across more rectifiers that operate sub-optimally on their efficiency curve, aspects of the disclosure provide for automatically deactivating some rectifiers by lowering voltage set-points. As power load to a rack decreases, the voltage of the current to a rectifier with a reduced voltage set-point falls below the set-point and turns off. Power is automatically redistributed to the remaining active rectifiers. The redistribution increases the power load onto the remaining rectifiers, allowing the rectifiers to perform more efficiently in converting AC power to DC power.

Abstract: Current imbalance may be detected and components reactively moved to correct the current imbalance. The components, such as rectifiers, machines, etc., may be moved from the most loaded phase to the least loaded phase. The imbalance may be detected at one or more power distribution units. Rebalancing may be performed using a model which preserves the number of components per rack, while limiting per-rack phase imbalance and minimizing imbalance among phases. Once the rebalancing has been computed, instructions for moving components according to the rebalancing may be generated.

Abstract: This disclosure describes a method to minimize disruption for throughput oriented jobs in power oversubscription services with a dynamic control. The mechanism controls power in a hardware-agnostic way, and the policy employs a multi-threshold approach that balances power safety with workload impact. Moreover, an alternative control mechanism ensures proper system operation while power measurements are unavailable.
