Abstract
A data storage system is operated for reduced power consumption, including regularly scanning usage patterns of data stored on a set of production storage devices to identify cold data whose usage is below a predetermined usage threshold, and adding the cold data of each scan to a collection of cold data. The production storage devices are operated in a normal power mode having normal per-device power consumption. Upon the collection of cold data reaching a predetermined size, (1) one of the production storage devices is designated as a green tier device, and (2) the collection of cold data is moved to the green tier device. The green tier device is operated in a low power mode having a lower per-device power consumption.
