Abstract

PURPOSE: To make it possible to transfer data between storage devices in the system through no central processing unit with a high efficiency by providing a bus line which connects plural storage devices mutually.
CONSTITUTION: This information processing system 1 is provided with central processing unit 3 including main storage device 2, plural external storate devices 41, 42...4n, I/O control circuit 5 which is provided between central processing unit 3 and external storage devices 4 and causes storage devices 2 and 4 in the system to perform data transfer mutually, and channel 6 which is provided between central processing unit 3 and I/O control circuit 5. When controller 9 in I/O control circuit 5 receives a command concerning transfer from central processing unit 3, data read or write is instructed to a required storage device, and data is transferred between storage devices through no main storate device.
