The method includes receiving, at a liquid cooling control subsystem, an incoming cooling liquid supply flow rate corresponding to an incoming cooling liquid supply being supplied to the DL RIHS.

The controller triggers each of the LC nodes to adjust the associated flow rate for that LC node to correspond to the received maximum flow rate cap for that node.

Abstract: A computer-implemented method enables rack-level predictive power capping and power budget allocation to processing nodes in a rack-based IHS. A rack-level management controller receives node-level power-usage data and settings from several block controllers, including current power consumption and an initial power budget for each node. A power consumption profile is generated based on the power-usage data for each node. A total available system power of the IHS is identified. A system power cap is determined based on the power consumption profiles and the total available system power. A current power budget is determined for each node based on an analysis of at least one of the power consumption profile, the initial power budget, the current power consumption, the system power cap, and the total available system power. A power subsystem regulates power budgeted and supplied to each node based on the power consumption profiles and the system power cap.
