Abstract
In at least one embodiment, a method of operating a multiple-data-storage-devices enclosure is disclosed. The method includes: receiving a first read request from a first requester device for a first requested data fragment; identifying a first target data storage device storing the first requested data fragment based at least partly on the first read request; activating, independently of receiving the first read request, only a subset of data storage devices in the enclosure, wherein the subset includes the first target data storage device; retrieving, based at least partly on the first read request and in response to activating the subset, the first requested data fragment from the first target data storage device; and transmitting the first requested data fragment to the first requester device.
