Abstract: A power consumption threshold is implemented to manage power consumed by a plurality of devices. A power consumption threshold may be selected for a data storage system having multiple drives. Policies may control operation of storage devices such as hard disk drives to ensure the power consumption threshold is not exceeded. The policies may implement procedures for scheduling hard disk drive operations based on disk drive power characteristics, scheduling maintenance tasks, managing device power states, and strategically scheduling device operations based on their current state. The policies may be implemented by a data manager application in communication with multiple tiers of a data storage system.

Abstract translation: 实现功耗阈值以管理由多个设备消耗的功率。 可以为具有多个驱动器的数据存储系统选择功耗阈值。 策略可以控制诸如硬盘驱动器之类的存储设备的操作，以确保不超过功耗阈值。 该策略可以实现基于磁盘驱动器功率特性来调度硬盘驱动器操作的程序，调度维护任务，管理设备电源状态，以及基于其当前状态来策略性地调度设备操作。 策略可以由与数据存储系统的多层通信的数据管理器应用来实现。
