Improved performance control of data storage arrays

To provide improved operation of data storage devices and systems, various systems, devices, methods, and software are provided herein. In a first example, a data storage system is presented. The data storage system includes data storage devices configured to store and retrieve data, power supply modules configured to provide power at least to the plurality of data storage devices, and a management controller configured to monitor performance characteristics associated with the power modules Reduced performance. Reacting to the reduced power state, the management controller is configured to make adjustments to a performance of the data storage devices to mitigate the degraded performance. 为了提供数据存储设备和系统的增强式操作，在此提供各种系统、装置、方法和软件。在第示例中，提出种数据存储系统。所述数据存储系统包括：数据存储设备，被配置用于存储和检索数据；电源模块，被配置为将功率提供给至少所述多个数据存储设备；以及管理控制器，被配置为监控与所述电源模块关联的功率性质以检测降级的功率状况。响应于所述降级的功率状况，所述管理控制器被配置为建立对所述数据存储设备的性能的调整以减缓所述降级的功率状况。
