PROBLEM TO BE SOLVED: To solve the problem that transfer performance is deteriorated because when data on the memory of one physical server have to be copied in the memory of two or more physical servers, using a general-purpose I/O interface which does not respond to multicast data transfer requires to issue a data write instruction to each of the plurality of physical servers, which results in increase in traffic between a server-to-server communication mechanism and an I/O switch. SOLUTION: The I/O switch is provided with a mechanism which comprises a register capable of holding a plurality of pieces of destination information in the control register of the server-to-server communication mechanism, and the register, when sending data to a plurality of destinations, capable of adding the plurality of pieces of destination information to the data to transfer data toward a plurality of destinations by the data write instruction of one time. The I/O switch shapes the data write instruction issued by the server-to-server communication mechanism to data write instructions to each of the destinations and simultaneously issues the data write instructions to the plurality of destinations.
