US Patent 10372185 Enhanced power control of data storage arrays

To provide enhanced operation of data storage devices and systems, various systems, apparatuses, 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 for storage and retrieval of data, power supply modules configured to provide power to at least the plurality of data storage devices, and a management controller configured to monitor power properties associated with the power supply modules to detect a degraded power condition. Responsive to the degraded power condition, the management controller is configured to establish adjustments to performance of the data storage devices to mitigate the degraded power condition.
