PROBLEM TO BE SOLVED: To solve the problem that it is difficult to fairly multiplex requests from a plurality of request sources. SOLUTION: A storage multiplexer 30 includes a plurality of reservation channels 32 to which the request of each request source is input and an output port 42. The output port 42 outputs the request to be transferred from the plurality of reservation channels 32 to a disk scheduler 20. Each reservation channel 32 accepts the reservation of bandwidth for processing the request from each request source. Time frames as time units for multiplexing the requests from the plurality of request sources are prepared, and the reservation channel 32 whose reservation bandwidth has been at least partially seized in response to the request to be output from the other reservation channel 32 in a certain time frame receives the compensation of the seized reservation bandwidth in the next time frame.
