ABSTRACT:
In a system which includes an input-output controller provided with channel paths for receiving input/output requests from higher-rank apparatus, and an external storage controller connected to the input-output controller through the channels, the input-output controller registers input-output requests issued for the external storage devices from the higher-rank apparatus in input-output request queues and transfer one or plural ones of the channel programs registered in the input-output request queues collectively to the external storage controller, which control execution of the transferred channel programs, so that channel command words included in each transferred channel program are executed at timings which are adapted to an operation of one of the external storage devices which is to be controlled by the channel program.
