Storage Read Error Correction With Dynamic Effort Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprise storage systems face challenges in dynamically adjusting error correction efforts to effectively handle errors during data retrieval, as existing methods lack the ability to adaptively manage error correction levels based on available resources and error severity.
Innovation Solution
The system dynamically adjusts error correction efforts by receiving an error correction level from a storage array controller, identifying errors, determining if the required effort exceeds the specified level, and returning an error condition to the controller, allowing for adaptive error correction based on resource availability and error severity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error correction effort level is increased to improve data retrieval reliability, then data retrieval reliability is improved, but resource utilization increases
Solution Approach 1:
The patent implements dynamic adjustment of error correction effort level based on real-time conditions. The storage device transitions from static error correction parameters to dynamic adaptation, modifying correction intensity according to detected error patterns and available resources, thereby resolving the contradiction between reliability and resource utilization
Solution Approach 2:
The system changes error correction parameters dynamically based on detected conditions. By adjusting error correction effort level as a variable parameter rather than maintaining a fixed value, the system optimizes the balance between data retrieval reliability and resource consumption according to actual operational needs
2Productivity
If error correction effort level is dynamically adjusted based on error severity, then data reconstruction efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the storage device monitors error conditions during data retrieval and uses this information to dynamically adjust error correction effort. This closed-loop control enables adaptive optimization of data reconstruction efficiency while managing device complexity through intelligent decision-making algorithms
Solution Approach 2:
The storage device autonomously adjusts its own error correction parameters based on detected error patterns without requiring external intervention. This self-service capability improves data reconstruction efficiency by enabling real-time adaptation while managing complexity through automated decision-making rather than manual configuration

AI summary
Dynamically adjusting an error correction effort level of a storage device, including: receiving, from a storage array controller, an error correction effort level to perform when attempting to read data from the storage device; identifying that an attempt to read the data resulted in an error; and determining whether an amount of error correction effort level required to attempt to correct the error exceeds the error correction effort level to perform when attempting to read data from the storage device.
