Load Imbalance Mitigation with Component Repositioning for Higher Power Subscription in Warehouse Scale Computers
DRIVE
December 7, 2023
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.
