PROBLEM TO BE SOLVED: To make an internal auxiliary storage device such as a disk device built in a certain information processor accessible from the other information processor at a high speed. SOLUTION: An operating system(OS) to be operated in the CPU 220 of an information processor 200 prepares a channel command word(CCW) command stream and transfer data or transfer data area on a main storage device 210 and instructs to start the operation of an input/output(I/O) function. An auxiliary memory control unit 240, which receives the instruction to start the operation of the I/O function, performs emulation processing to the respective commands of the CCW command stream, generates a command set and requests data read to a disk device 150 built in an information processor 100. According to the instruction of the command set of this read request, the built-in disk device 150 transfers a response and data through communication equipment 145 and communication bus 190 to the information processor 200.
