determining, by the communication fabric, a destination microarray controller from among the plurality of microarray controllers, wherein the destination microarray controller controls another one or more of the storage devices, wherein the mapping of the one or more of the storage devices to the microarray controller is different than the mapping of the other one or more storage devices to the destination microarray controller such that each one of the plurality of storage devices is controlled by one microarray controller, and wherein each microarray controller is the only assignor of its own storage devices;

sending, from the communication fabric to the microarray controller, the data specified by the request for data; and

receiving, at the microarray controller from the communication fabric, the data specified by the request for data.

8. The method of claim 7 , further comprising:

sending, from the communication fabric to the destination controller, a request for the data specified in the request from the microarray controller to the communication fabric;

sending, from the destination microarray controller to the communication fabric, the data specified by the request for data; and

receiving, at the communication fabric from the destination microarray controller, the data specified by the request for data.

9. The method of claim 7 , wherein the plurality of microarray controllers includes microarray controllers configured to implement different storage management systems, wherein the different storage management systems include at least two of a block-based storage management system, a file-based storage management system, or an object-based storage management system.
