Networked Storage Repair Function for Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage device failures in information handling systems lead to downtime and productivity losses due to hardware and software issues, such as hard drive failures and malware corruption, which existing technologies do not adequately address.
Innovation Solution
A storage device failure recovery system that includes a network-connected storage IHS and user IHS with a storage repair function, which provides a storage device image over the network, detects failures, and performs recovery procedures by restoring the storage system using the image, allowing the user IHS to operate with an alternate service environment and repair software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage device failures are addressed using traditional methods (hard drive replacement or operating system reinstallation), then the storage system can be restored, but the system experiences significant downtime and productivity loss
Solution Approach 1:
The system creates and stores backup images of storage devices before failures occur. When a failure is detected, the pre-existing backup image can be immediately restored without needing to perform time-consuming recovery operations, thus minimizing downtime while ensuring reliability
Solution Approach 2:
The system creates a copy (backup image) of the storage device data and stores it separately. Upon failure, this copy is used to restore the original system, allowing rapid recovery without requiring complex repair operations, thereby reducing downtime while maintaining system availability
2Reliability
If storage device failures are addressed using traditional methods, then the storage system can be restored, but the repair process is complex and requires significant user intervention
Solution Approach 1:
The system automatically detects storage device failures and initiates the recovery process using pre-stored backup images without requiring user intervention. The automated detection and recovery mechanisms simplify the repair process while ensuring reliable restoration of the storage system
Solution Approach 2:
The system continuously monitors storage device health and provides feedback about their condition. When failures are detected, this feedback triggers automatic recovery procedures, reducing the complexity of manual repair processes while maintaining reliable system restoration
3Reliability
If storage device failures are addressed using traditional methods, then the storage system can be restored, but user productivity is significantly impacted due to system unavailability
Solution Approach 1:
By creating and storing backup images before failures occur, the system enables immediate restoration when failures are detected. This preliminary preparation minimizes the time the system is unavailable, thereby maintaining user productivity while ensuring reliable restoration
Solution Approach 2:
The system maintains a copy of the storage device data that can be immediately deployed upon failure. This copying approach allows rapid system restoration without requiring complex repair operations, thus minimizing productivity impact while ensuring reliable system recovery

AI summary
A storage device failure recovery system includes a storage IHS and a user IHS coupled together over a network. The user IHS includes a storage system having a storage device, and a storage repair function that periodically provides a storage device image over the network to the storage IHS using data from the storage device. The storage repair function detects a failure of the storage device and streams an operating system on the user IHS using the storage device image stored on the storage IHS. While streaming the operating system on the user IHS using the storage device image stored on the storage IHS, the storage repair function analyzes the failure of the storage device, determines a storage system failure recovery procedure, and performs the storage system failure recovery procedure to restore the storage system while a user remains productive on the user IHS via the streamed operating system.
