Patent number: 8312186Abstract: The correspondence of the respective ports and the respective microprocessors is dynamically changed based on the load of the respective microprocessors. When an open port MP including a plurality of ports connected to a host computer receives an I/O request from the host computer via a port, it specifies an MPPK to become the transfer destination of the I/O request, and transfers the I/O request to the specified MPPK. Each MP belonging to the MPPK that received the I/O request selects either an exclusive mode where a single MP exclusively performs the processing of the I/O request, or a share mode where two or more MPs share the processing of the I/O request. Each MP selects the exclusive mode or the share mode corresponding to when load information concerning the ports shows a low load or high load condition, respectively, and executes the I/O processing accordingly.Type: GrantFiled: September 29, 2009Date of Patent: November 13, 2012Assignee: Hitachi, Ltd.Inventors: Takashi Ochi, Takahiko Takeda, Yasuhiko Yamaguchi
