Abstract
A data storage system has a first set of storage devices, a second set of storage devices, and a controller. The controller is arranged to (i) activate a first set of storage devices and deactivate a second set of storage devices prior to an amount of storage capacity currently used in the data storage system reaching a predefined storage capacity threshold of the data storage system. The controller is further arranged to (i) monitor the amount of storage capacity currently used in the data storage system in view of the predefined storage capacity threshold, and (ii) maintain activation of the first set of storage devices and automatically activate the second set of storage devices in response to the amount of storage capacity currently used in the data storage system reaching the predefined storage capacity threshold.
