Automated Log Redaction Using Configurable Obfuscation Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems face inefficiencies in managing storage drives, particularly in flash-based systems, due to the need for both higher-level and lower-level processes, leading to redundant operations and reduced reliability.
Innovation Solution
Implementing a direct-mapped flash storage system where higher-level processes manage data operations without involving lower-level storage controllers, utilizing zones and allocation units to optimize data management and reduce redundant writes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both higher-level and lower-level processes are involved in managing storage drives, then comprehensive data management is achieved, but redundant operations occur and reliability decreases
Solution Approach 1:
The patent extracts and removes the lower-level storage controller process from the data management hierarchy. By having higher-level processes directly manage flash storage drives without intermediate lower-level controllers, the system eliminates redundant operations and improves reliability while maintaining comprehensive data management capabilities.
2Loss of substance
If traditional storage management with multiple process levels is used, then data management coverage is comprehensive, but write operations become redundant and wear increases
Solution Approach 1:
The patent removes the lower-level storage controller that was causing redundant write operations. Higher-level processes now directly manage flash storage drives, eliminating the duplicate write operations that occurred when data passed through multiple process levels, thereby reducing storage wear and improving write efficiency.
Solution Approach 2:
The patent implements preliminary data management actions at the higher-level process stage, where data is organized and prepared before being written to flash storage drives. This preliminary organization prevents the need for subsequent rewrite operations, reducing overall write次数 and storage wear.
3Productivity
If higher-level processes directly manage flash storage drives without lower-level controllers, then redundant operations are reduced and reliability improves, but data management complexity increases
Solution Approach 1:
The patent merges the functions of lower-level storage controllers into higher-level processes. By combining data management and direct drive control into unified higher-level processes, the system reduces redundant operations and improves efficiency while the modular architecture manages the complexity through clear functional boundaries.
