Abstract:
The storage controller of the present invention is able to reduce the amount of purge message communication and increase the processing performance of the storage controller. Each microprocessor creates and saves a purge message every time control information in the shared memory is updated. After a series of update processes are complete, the saved purge messages are transmitted to each microprocessor. To the control information, attribute corresponding to its characteristics is established, and cache control and purge control are executed depending on the attribute.
