File operations on files in a peripheral system are controlled by an intelligent controller with a file processor. The files are accessed as if the intelligent controller were an addressable virtual storage space. This is accomplished first by communicating controller commands for the intelligent controller through read/write commands addressed to a Command Region of a virtual storage device. The controller commands set up a Mapped Data Region in the virtual storage device for use in controlling data transfer operations to and from the peripheral system. With the Mapped Data Regions set up, blocks of data are transferred between the host and the intelligent controller in response to read/write commands addressed to the Mapped Data Region of the virtual storage device. In an additional feature of the invention file operations are communicated between host and controller through a device driver at the host and a device emulator at the intelligent controller. If the address in the device write/read command is pointing to the Command Region of the virtual storage device, a Command Region process interprets and implements the controller operation required by the controller command embedded in the device write/read command.

Mass storage system controller apparatus receives requests for access to files in a data storage system and manages access to the files in the data storage system, the data storage system having a plurality of storage devices and the requests being addressed to the data storage system as a single virtual storage device having addressable Command Regions allocated to controller commands and addressable Mapped Data Regions allocated for data storage. The apparatus includes a file system to manage access to files in the data storage system, the file system having a processor acting as a Command Region processor and acting as a Mapped Data Region processor. A disk emulator responds as a disk drive device to write/read commands and passes the write/read commands addressed to Command Regions of the virtual storage device to the Command Region processor, the write/read commands addressed to Command Regions containing controller commands for the file system. The Command Region processor responds to controller commands in the write/read commands and processes the controller commands to control files in the data storage system. The disk emulator responds as a disk drive device to write/read commands and passes write/read commands addressed to a Mapped Data Region of the virtual storage device to the Mapped Data Region processor.

An electronic file control system is presented that generates a mirror copy of all controlled or “original” files. The system then allows controlled access to the original files. However, changes to the original files are not reflected in the mirror copies until authorized by an approving entity. That is, while users may access and change the original files, the utility may revert to the mirror copy of the file if the user does not have the authority to make the changes. That is, after the unauthorized user alters (e.g., edits, deletes, etc.) a file, the utility may replace the unauthorized edited file with the last authorized version of the file (i.e the mirror copy). Alternatively, when such changes are approved, the mirror copy may be updated and thereby become the latest authorized version of the file. Such controlled access to and replacement of files allows for controlling numerous business processes.
