Direct-Mapped Flash Storage via OS-Level Controller Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional storage systems face inefficiencies in data management and storage operations, particularly in handling flash drives without integrated storage controllers, leading to unnecessary write operations and reduced reliability.
Innovation Solution
Implementing a direct-mapped flash storage system where the operating system initiates and controls data operations across multiple flash drives, eliminating the need for lower-level storage controllers and reducing redundant write processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional storage controllers are used to manage flash drives, then data operations can be controlled and directed, but unnecessary write operations occur and reliability is reduced
Solution Approach 1:
The patent extracts the storage controller functionality from the traditional storage system architecture. Instead of using dedicated storage controllers to manage flash drives, the system eliminates these intermediate controllers and allows the operating system to directly manage data operations across multiple flash drives, thereby removing the source of redundant write operations and improving both reliability and write efficiency
2Ease of operation
If storage controllers manage data operations, then data can be routed and controlled, but redundant write processes occur reducing efficiency
Solution Approach 1:
The operating system assumes multiple roles by directly managing data operations across flash drives without dedicated storage controllers. The OS performs functions previously handled by specialized controllers, including data routing, address translation, and write management, thereby eliminating redundant operations while maintaining operational control through a universal management layer
3Quantity of substance
If multiple flash drives are used for storage, then storage capacity and flexibility increase, but coordination and control become more complex
Solution Approach 1:
The patent merges the control functions for multiple flash drives into a single unified management approach handled by the operating system. Instead of each flash drive requiring separate controller management, the OS consolidates coordination tasks including data distribution, address mapping, and write operation management across all flash drives, thereby maintaining high storage capacity while reducing overall system complexity
