Data storage device enclosure and module

A data storage enclosure comprising:

• a data storage device in a first side of the enclosure;
• a first electronics module received in a first bay in a second side of the enclosure opposing the first side, the first electronics module including a first controller and an additional data storage device;
• a second electronics module received in a second bay in a second side of the enclosure, the second electronics module including a second controller and an additional data storage device;
• the first controller configured to communicate with the data storage device in the first side of the enclosure, and with the additional data storage device in the second electronics module;
• and
• the second controller configured to communicate with the data storage device in the first side of the enclosure, and with the additional data storage device in the first electronics module.

A system comprising:

• a data module bay in a front of an enclosure;
• a first bay in a back of the enclosure, the first bay adapted to receive a first electronics module, a first controller, and a first back storage device therein;
• and
• a second bay in the back of the enclosure, the second bay adapted to receive a second electronics module, a second controller, and a second back storage device therein;
• the first back bay having a first connector to operably connect the first controller to the front data module bay, and a second connector to operably connect the first controller to the second back storage device;
• and
• the second back bay having a third connector to operably connect the second controller to the front data module bay, and a fourth connector to operably connect the second controller to the first back storage device.
