Monitoring of shared server set power supply units

Power monitoring in a server set that has a shared power supply system that includes multiple power supply unit sets that each provides power to the server set. A controller monitors power usage of the server set, and evaluates the monitored power usage against the power supply capability of each of the power supply unit sets. Based on the evaluation, the controller can detect when a particular power supply unit set is no longer capable of solely providing all of the power that the server set is consuming or anticipated to consume, and then reduce power accordingly so that the particular power supply unit set could provide such power. 在具有共享供电系统的服务器组中的电力监测，共享供电系统包括多个供电单元组，每个供电单元组向服务器组提供电力。控制器监测服务器组的电力使用，并且针对每个供电单元组的供电能力来评估所监测的电力使用。基于该评估，控制器可以检测特定供电单元组何时不再能够单独提供服务器组正在消耗或预期消耗的所有电力，并且相应地减少电力，使得特定供电单元组能够提供这样的电力。
