    摘要： A switch unit, which is connected to one or more computers and one or more storage systems, comprises an update function for updating transfer management information (a routing table, for example). The storage system has a function for adding a virtual port to a physical port. The storage system migrates the virtual port addition destination from a first physical port to a second physical port and transmits a request of a predetermined type which includes identification information on the virtual port of the migration target to the switch unit. The transfer management information is updated by the update function of the switch unit so that the transfer destination which corresponds with the migration target virtual port is the switch port connected to the second physical port.

    摘要： Among a plurality of microprocessors 12, 32, when the load on a microprocessor 12 which performs I/O task processing of received I/O requests is equal to or greater than a first load, the microprocessor assigns at least an I/O task portion of the I/O task processing to another microprocessor 12 or 32, and the other microprocessor 12 or 32 executes at least the I/O task portion. The I/O task portion is a task processing portion comprising cache control processing, comprising the securing in cache memory 20 of a cache area, which is one area in cache memory 20, for storage of data.
