Abstract

A computer system having a virtual drive array controller incorporated therein. The virtual drive array controller enables plural physical devices, which may be of a single type of device or a combination of multiple types of devices, to be represented to the computer system as a single logical drive. The virtual drive array controller includes a front end coupled to a secondary storage bus and a back end to which plural physical devices are coupled. Additional virtual drive array controllers may be arranged in a cascading configuration by coupling the additional virtual drive array controllers to the back end of the virtual drive array controller.
