Rack mountable computer system that includes microarray storage systems

A method comprising:

• by first program instructions executing on a computing device:
• sending, from a microarray controller to a communication fabric, a request for data, wherein the microarray controller is one of a plurality of microarray controllers housed within a drive bay of an enclosure, wherein the enclosure comprises a plurality of storage devices, and wherein the microarray controller controls one or more of the storage devices;
• 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.

A computer program product disposed upon a computer readable medium, wherein the computer readable medium is not a signal, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

• sending, from a microarray controller to a communication fabric, a request for data, wherein the microarray controller is one of a plurality of microarray controllers housed within a drive bay of an enclosure, wherein the enclosure comprises a plurality of storage devices, and wherein the microarray controller controls one or more of the storage devices;
• 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.
