Abstract
In a computer system having an interface with an I/O bus given disconnect/reconnect functions and a plurality of magnetic disk subsystems connected with the I/O bus, control divides a file at a disk access time with reference to disk management information, file management information and file descriptor translation information to read/write a plurality of such files asynchronously. Thus, high speed file access can be realized by only the plurality of magnetic disk subsystems without requiring any special control hardware. A corresponding relation between subfiles in a virtual directory and the application request file can be taken to construct the directory, thus making the divided storage transparent to the application.
