Autonomous Power Sparing Storage

摘要

Power saving logic in a data storage system with multiple data storage devices is distributed from a central controller to each individual device. Power saving logic, including algorithms used to conserve power when the data storage device is not needed, are stored and executed on each individual data storage device. Hence, rather than implementing a power saving algorithm from a single central sever, each and every data storage system may carry out power saving techniques individually. This reduces the load on the central server and utilizes processing power available on data storage devices such as a disk drive.

主权项

1. A data storage device for managing power consumption:
a rotating medium for storing non-volatile data; a processor; and one or more modules stored on the data storage device and executable by the processor to control a power state of the rotating medium based at least in part on a queued request to read or write to the rotating medium.
