Onboard computer data storage, access, and caching system

摘要

A controller and memory unit for a host computer has a primary controller coupled to a parallel bus interface connectable or connected to the host computer, and by cable connections to one or more remote memory disk units, one or more secondary controllers coupled by parallel bus to the primary controller, and one or more solid-state memory modules coupled by parallel bus one-to-one with the secondary controllers. The primary controller provides read/write access to the remote memory disk units and read/write access to each of the solid-state memory modules through the associated secondary controller.
