METHOD AND APPARATUS FOR USING A STORAGE SYSTEM AS MAIN MEMORY

A data storage and access system for use with a processor having a final level cache (FLC) cache system, configured to function as main memory and receive a data request from the processor, that has processor cache. The FLC system comprises a first FLC module having a first FLC controller and first memory, where the first FLC module is configured to receive the data request from the processor. The FLC system additionally comprises a second FLC module having a second FLC controller and second memory. The second FLC module is configured to receive, responsive to the first FLC module not having the data requested by the processor, the data request from the first FLC module and forward the data request to a storage drive or a third FLC module to retrieve the data identified by the data request.
