Abstract
An electronic device may include a plurality of data storage devices including a master storage device and one or more slave storage devices. Each of the data storage devices comprises a storage configured to store data and a controller configured to control data input/output operations with respect to the corresponding storage. The controller of the master storage device receives device information including identification information, capacity information and physical configuration information from each of the slave storage devices, and the controller of the master storage device changes an electric power mode of at least one of the slave storage devices selected based on capacity margin of the master storage device and the device information.
Claims14
An electronic device comprising:
- a data storage device group, including a plurality of data storage devices, wherein the data storage devices function as a storage medium for a host device,
- wherein each of the data storage devices comprises a) a memory device configured to store data and b) a controller configured to control data input/output operations with respect to the memory device,
- wherein a first controller of a first data storage device receives device information including identification information, capacity information and physical configuration information from a storage group comprising remaining data storage devices other than the first data storage device, and the first controller of the first data storage device changes an electric power mode of one or more selected data storage devices based on a) a first capacity margin, which is remaining storage capacity of the first data storage device and b) the device information of the data storage devices comprised in the storage group,
- wherein the first controller and the selected data storage device are in data communication with each other, and
- wherein the first controller is configured to decide the selected data storage devices when the first capacity margin of the first data storage device is not less than a preset threshold value.
A data storage device comprising:
- a memory device configured to store data;
- a controller of the memory device configured to control data input/output operations to the memory device,
- wherein the controller comprises:
- a storage device interface configured to receive device information including identification information, capacity information and physical configuration information from a storage group comprising one or more other data storage devices;
- and
- an electric power manager configured to change an electric power mode of a selected data storage device selected among the storage group based on a) a first capacity margin, which is a remaining storage capacity of the memory device, and b) the device information of each of the one or more data storage devices comprised in the storage group,
- wherein the controller and the storage group are in data communication with each other, and
- wherein the controller is configured to decide the selected data storage device when the first capacity margin of the memory device is not less than a preset threshold value.
A method of operating a data storage device, the data storage device including a) a memory device configured to store data and b) a controller configured to control data input/output operations to the memory device, the method comprising:
- receiving, by the controller, device information including identification information, capacity information and physical configuration information of a storage group comprising one or more other data storage devices;
- determining, by the controller, a first capacity margin of the memory device;
- selecting, by the controller, a selected storage device among the one or more other data storage devices comprised in the storage group based on a) the first capacity margin of the memory device, which is a remaining storage capacity of the memory device, and b) the device information of the one or more other data storage devices comprised in the storage group;
- and
- changing, by the controller, an electric power mode of the selected data storage device,
- wherein the controller and the storage group are in data communication with each other, and
- wherein the controller is configured to decide the selected data storage device when the first capacity margin of the first memory device is not less than a preset threshold value.
