Storage Sector Differential OS Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage devices face inefficiencies in updating the operating system due to the large file size of new backup operating systems, leading to lengthy download times and inconvenience.
Innovation Solution
A data storage device with a controller, microprocessor, and network communication unit that downloads and updates the backup operating system using an operating system differential file, allowing for quick updates by switching between different system storage sectors and utilizing a boot pointer offset procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a completely new backup operating system is downloaded from a cloud server, then the backup operating system can be updated, but the file capacity is very large which takes a long time to download
Solution Approach 1:
The patent extracts only the differential portions (changes) from the new operating system rather than transferring the complete system. The differential file contains only the modifications needed to update the backup operating system, significantly reducing the data transfer volume and download time while maintaining the ability to perform complete system updates.
2Loss of time
If the backup operating system file size is reduced by using differential files, then download time is reduced, but the complexity of the update procedure increases
Solution Approach 1:
The patent introduces a differential file as an intermediary element between the new operating system and the backup operating system. This differential file serves as a mediator that contains only the necessary changes, simplifying the transfer process while the controller handles the complexity of applying these differences to generate the updated backup system.
3Adaptability or versatility
If multiple system storage sectors are used to store different backup operating systems, then system recovery flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent divides the storage system into multiple independent system storage sectors, each capable of holding a separate backup operating system. This segmentation allows the controller to manage different backup versions in isolated segments, providing flexibility for system recovery while organizing the complexity into manageable, independent units through structured sector management.
Data Source
AI summary
A data storage device includes a controller, a data storage unit, a microprocessor, and a network communication unit. The controller includes a firmware. The data storage unit includes a first system storage sector and a second system storage sector. The first system storage sector stores an original operating system, and the second system storage sector stores a backup operating system. When the data storage device receives an operating system differential file from a cloud management platform, the firmware updates the backup operating system in the second system storage sector to obtain a new version of backup operating system. Accordingly, the backup operating system of the data storage device can be quickly updated by downloading a small file size of the operating system differential file so as to enhance the convenience for the updating of the backup operating system.
