Virtual Storage Device File Access via OS Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems face issues with asynchronous file access between control and managed devices, leading to data damage and system errors due to the inability of the file system to recognize updates made outside its hierarchical structure, restricting bi-directional access and limiting application range.
Innovation Solution
A method that simulates a physical storage device on the managed device via a system management device, allowing access operations to be performed directly through the operating system rather than the file system, enabling the control device to access and update files on the physical storage device without involving the file system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the managed device writes a file into the virtual storage device through the system management device, then the file can be updated on the physical storage device, but the file system of the control device cannot recognize the update, causing asynchronous files and data damage
Solution Approach 1:
The patent introduces a file synchronization mechanism that acts as an intermediary between the control device and managed device. When a file is written to the virtual storage device, the system management device captures the write operation and synchronizes it to the physical storage device, ensuring the file system recognizes the update and maintaining data consistency across devices.
Solution Approach 2:
The patent implements a feedback mechanism where the system management device monitors file operations on the virtual storage device and provides feedback to update the file system's recognition of these changes. This feedback loop ensures that writes performed through the virtual storage device are properly reflected in the physical storage device's file system, preventing asynchronous file issues.
2Adaptability or versatility
If the control device and managed device access files bi-directionally, then the application range is expanded, but asynchronous file access occurs leading to system errors
Solution Approach 1:
The patent implements dynamic access control that adapts based on the operation type. For write operations, access is directed through the system management device to ensure synchronization. For read operations, bi-directional access is permitted. This dynamic adjustment maintains system stability while preserving access flexibility for different use cases.
Solution Approach 2:
The patent applies different access rules to different devices and operations. The managed device is granted full bi-directional access capability for local operations, while the control device's access is regulated through the system management device for file write operations. This localized quality control allows flexibility where needed while maintaining stability where critical.
3Stability of the object's composition
If the file system is used for file access operations, then hierarchical structure is maintained, but updates made outside the file system cannot be recognized
Solution Approach 1:
The patent merges the file system's hierarchical structure with the system management device's direct access capability. File read operations continue to use the file system's hierarchical structure for organization and access. File write operations are captured by the system management device, which then synchronizes them back to the file system, combining the benefits of structured access and update recognition.

AI summary
A method for accessing files in a management system, including a control device, a managed device, and a system management device, includes simulating a physical storage device of the control device to the managed device, to form a virtual storage device in the managed device, outputting a request command to the system management device via an operating system and not via a file system when the managed device accesses a file of the virtual storage device, and performing access operation of the file in the physical storage device via an operating system of the control device and not via a file system of the control device according to the request command.
