PURPOSE:To improve a throughput by storing the file read requests into a queue after allocating them evenly in accordance with the stored contents of a control table. CONSTITUTION:The queues 5 and 6 are set opposite to a master filing device 9 and a slave filing device 10 and store the file read requests. The control tables 3 and 4 store the total number of file read request stored in both queues 5 and 6. A data access task 1 allocates evenly the file read requests supplied from an application task in accordance with the stored contents of the managing tables 3 and 4 and stores these requests into the queues 5 and 6 as long as both filing devices 9 and 10 are normal. Thus the file read requests are scattered into both devices 9 and 10 and the file read processing time is extremely shortened.
