PROBLEM TO BE SOLVED: To uniquely decide priority at the time of changing or adding the input/output request priority of a certain system by making it unnecessary to reconsider input/output request priority set in another system. SOLUTION: This input/output request priority controller is constituted of a means for storing a system priority level where the priority of an input/output request to an input/output device is decided for each system and application priority where the priority is decided for each application, a means for extracting the system priority level and the application priority, and for calculating the priority of the input/output request based on the extracted system priority level and application priority, and for setting the calculated priority in the priority table to prepare a priority table and a means for extracting the priority corresponding to the application from the priority table when an input/output request is made from the application, and for making the input/output request to the input/output device by using the extracted priority.
