Abstract

PURPOSE:To attain the multiplexing of storage devices by low overhead and to effectively utilize the storage devices by arranging a device address correspondence table storing file numbers and the files in a storage controller for controlling plural storage devices. CONSTITUTION:Processors 100a-100n are connected to plural storage devices 300alpha-300gamma through the storage controller 200. The device 200 consists of multiplexing control parts 210 (210a-210n), a multiplexing control memory 220 and address conversion parts 230 and stores file numbers and storage device addresses correspondingly. Access requests are inputted from the processors to the control parts 210a-210n and device addresses, file numbers, intra-file relative addresses, and data transfer directions are respectively inputted. When the files are to be multiplexed, the file data are distributively outputted to conversion parts 230alpha-230gamma. Thus, the multiplexing of the storage devices is attained by low overhead and the storage device can be effectively utilized.
