INFORMATION PROCESSOR, COMPUTER-READABLE RECORDING MEDIUM IN WHICH INPUT/OUTPUT CONTROL PROGRAM IS RECORDED, AND METHOD FOR CONTROLLING INPUT/OUTPUT

摘要

An I/O controller simultaneously performs first I/O control on a plurality of storing devices, which configure a redundant system, in accordance with a first I/O request from an upper application. An response processor outputs, when the response processor receives a process completion notification from a first storing device that is one of the plurality of storing devices as a result of the first I/O control simultaneously performed on the plurality of storing devices, a completion response representing completion of a process related to the first I/O request to the upper application. This configuration makes it possible to rapidly respond to the I/O control of the upper application with a process completion and to reduce the time length occupied by the I/O control of the upper application.

1. An information processor comprising:
an input/output (I/O) controller that simultaneously performs first I/O control on a plurality of storing devices, which configure a redundant system, in accordance with a first I/O request from an upper application; and a response processor that outputs, when the response processor receives a process completion notification from a first storing device that is one of the plurality of storing devices as a result of the first I/O control simultaneously performed on the plurality of storing devices, a completion response representing completion of a process related to the first I/O request to the upper application.
