ABSTRACT:
A data processing system that includes an improved architecture for providing hot spare storage devices. Specifically, the data processing includes a bus that is connected to one or more computer systems and a number of storage subsystems. Each storage subsystem includes storage devices and a controller. The controller in a storage subsystem provides the connection to the bus and an interface for controlling data transfers to and from the storage device. A backup storage system is connected to the bus. The data processing system also includes a detection means for detecting a failure of a storage device within one of the plurality of storage subsystems and a backup means for using the backup storage device to replace the failed storage device.
