Abstract
A technique to distribute processing to meet a request from other system without partializing the processing to specific processor and can execute processing efficiently while adopting configuration to control one port unit by multiple processors at channel adapter of disk array system. CHA of a controller has a port unit carrying out interface operation and multiple host processor units having host processors. Multiple processors operate in parallel and control the port unit. When the port unit receives a request from other system, the first processor takes charge of the processing on the basis of the judgment of the processing load condition in processors including itself and in the event that the second processor is assigned the processing, the first processor communicates with the protocol unit and transfers the request to the second processor unit to enable the second processor to take charge of the processing.
