ABSTRACT:
An I/O control system includes an I/O control unit, a plurality of I/O devices, the start process prior to a data transfer process of the I/O device being off-line processed from the I/O control unit, and a data transfer path for data transferring to the I/O device, the data transfer being performed for one I/O device at a time. The I/O control unit controls an I/O device in such a way that the start process of the I/O device completes at the time when another I/O device under data transfer completes its data transfer, thus improving the utilization of a data transfer path.
