External-Interrupt Data Storage Control for Runtime Performance Issues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage devices lack the ability to dynamically adjust their behavior in response to user-perceived performance issues without explicit instructions from the host, leading to suboptimal performance and user experience.
Innovation Solution
Implementing a data storage device with a controller that receives external interrupts from a host application, allowing it to autonomously address performance issues such as thermal throttling, garbage collection, and DAC shift updates based on user feedback, without specific host-directed actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data storage devices follow predefined behavior paths without dynamic adjustment capability, then device complexity is reduced and ease of manufacture is improved, but user experience and performance optimization deteriorate when performance issues occur
Solution Approach 1:
The controller autonomously diagnoses and addresses performance issues using internal diagnostics and predefined actions triggered by host interrupts, eliminating the need for explicit host instructions and reducing the burden on the host system while maintaining adaptability
Solution Approach 2:
The host application provides feedback through interrupts when performance problems are detected, enabling the controller to adjust its behavior dynamically based on actual performance conditions while maintaining a relatively simple predefined architecture
2Extent of automation
If data storage devices require explicit host instructions to address performance issues, then device autonomy is reduced and ease of operation is improved, but responsiveness and user experience deteriorate
Solution Approach 1:
The controller performs autonomous diagnostics and executes corrective actions independently once triggered by a host interrupt, eliminating the need for the host to specify detailed remediation steps while maintaining simple interrupt-based initiation
3Reliability
If data storage devices implement comprehensive diagnostic and corrective capabilities, then performance problem resolution is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The controller is pre-configured with a library of diagnostic routines and predefined corrective actions for common performance issues, allowing it to rapidly respond to problems without requiring complex real-time decision-making or extensive manufacturing complexity
Solution Approach 2:
The system implements dynamic behavior adjustment through interrupts that allow the host to trigger specific diagnostic and corrective actions based on performance conditions, balancing reliability with manageable complexity through event-driven operation
