Storage Medium Redundant Space Allocation for Automatic Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage medium management methods require manual intervention when components fail, leading to low management efficiency and increased costs.
Innovation Solution
The method configures redundant space based on maintenance-free rate, period, AFR, and total components to automatically transfer data to redundant space upon failure, eliminating the need for manual component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual component replacement is used when storage medium fails, then the system can be restored, but management efficiency is low and operational costs are high
Solution Approach 1:
The patent pre-allocates redundant storage space before any failure occurs. This redundant space is reserved and configured in advance to automatically receive data from failed components, eliminating the need for manual intervention when failures happen.
Solution Approach 2:
The system implements automatic failure recovery where the storage system itself manages the data migration to redundant space without human intervention. The system autonomously detects failures, transfers data, and restores functionality, making the maintenance process self-service oriented.
2Productivity
If redundant space is preconfigured for automatic failure recovery, then management efficiency improves, but storage capacity available for user data decreases
Solution Approach 1:
The patent implements a balanced approach where only the minimum necessary redundant space is allocated based on failure probability calculations. This partial action approach ensures sufficient redundancy for automatic recovery while minimizing the impact on user-available storage capacity.
Solution Approach 2:
The system dynamically adjusts the allocation of redundant space based on calculated parameters such as failure rates, component quantities, and maintenance-free period requirements. This allows optimization of the balance between redundancy level and available storage capacity.
3Extent of automation
If redundant space is configured based on maintenance-free rate and period, then automatic maintenance-free management is achieved, but system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors failure rates and performance metrics, then uses this information to optimize redundant space allocation and maintain maintenance-free operation. The feedback loop enables automatic adjustment without increasing operational complexity.
Solution Approach 2:
The complex calculations for determining optimal redundant space based on maintenance-free rates and periods are performed in advance during system configuration. This preliminary action consolidates the complexity into an initial setup phase rather than ongoing operations, simplifying daily system management.

AI summary
This application discloses a storage medium management method and apparatus, and a readable storage medium, and relates to the field of data storage technologies. The method includes: when detecting that a component in a storage medium fails, recovering, based on a specified RAID policy, data stored in the failed component; and saving recovered data into redundant space of the storage medium, and mapping an address of the failed component into the redundant space, where the redundant space is fixedly preconfigured or is configured after a maintenance-free rate, a maintenance-free period, an AFR of the storage medium, and a total quantity of components included in the storage medium are determined, the maintenance-free rate and the maintenance-free period are carried in a configuration instruction for the storage medium or obtained by querying a user-defined register, and the AFR is obtained by querying or carried in the configuration instruction. In this application, a user does not need to manually replace the component, and maintenance-free management can be implemented on the storage medium by using the redundant space, thereby improving management efficiency.
