Hard Disk Movement Recognition in Storage Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional block storage devices do not allow for flexible movement of hard disks between or within hard disk arrays, limiting the efficient allocation and use of storage space, as once a hard disk is installed, it cannot be moved without replacement.
Innovation Solution
A method and system for recognizing hard disk movement, which includes identifying hard disk information, determining the movement type, judging the validity of the movement, and updating the hard disk information, allowing hard disks to be moved between or within hard disk arrays if the movement is valid, enabling flexible use and allocation of storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hard disk movement is not permitted in conventional block storage devices, then system stability and data security are maintained, but storage space allocation flexibility and operational efficiency deteriorate
Solution Approach 1:
The patent applies the dynamics principle by enabling hard disks to move from static fixed positions to dynamic repositionable locations within the hard disk array. The system allows hard disks to be relocated between slots and between arrays based on operational needs, transforming the rigid static configuration into a flexible dynamic one while maintaining stability through controlled validation mechanisms.
Solution Approach 2:
The patent implements feedback by introducing a validation mechanism that detects hard disk movement and provides feedback to the system. The movement detection unit identifies when a hard disk is moved, and the validation unit determines whether the movement is valid based on predefined conditions, allowing the system to respond appropriately while maintaining reliability.
2Ease of operation
If hard disk movement recognition system is introduced, then storage space allocation flexibility is improved, but device complexity and system configuration requirements worsen
Solution Approach 1:
The patent applies the self-service principle by enabling the system to automatically detect and validate hard disk movements without requiring manual intervention. The movement detection unit automatically identifies when hard disks are moved, and the validation unit autonomously determines whether the movement is valid based on predefined conditions, reducing the need for complex manual configuration and management.
Solution Approach 2:
The patent implements parameter changes by modifying the system's operational parameters to accommodate hard disk movement. The system changes its state from a fixed configuration to a dynamic one by updating position information, movement status, and validation parameters, allowing flexible storage management while managing complexity through parameter-based control.
3Productivity
If hard disk movement validation mechanism is implemented, then operational flexibility is enhanced, but processing time and system response time worsen
Solution Approach 1:
The patent applies the preliminary action principle by pre-establishing validation rules and conditions before hard disk movement occurs. The system prepares validation criteria in advance, allowing rapid assessment of movement validity without time-consuming analysis during the actual movement process, thus enhancing efficiency while minimizing validation time.
Solution Approach 2:
The patent implements the skipping principle by enabling the system to quickly validate hard disk movements by skipping unnecessary complex checks and focusing only on essential validation criteria. When movement conditions are met, the system rapidly approves the movement without prolonged processing, reducing validation time while maintaining operational efficiency.

AI summary
A system and method of recognizing a hard disk movement, the system and method including recognizing hard disk information recorded in a hard disk in response to the hard disk being moved to a slot in a hard disk array, determining the movement type of the hard disk based on the recognized hard disk information, judging validity of the hard disk movement based on the movement type, and updating the hard disk information of the hard disk in response to the hard disk movement being judged as valid, wherein the hard disk information comprises position information of the hard disk in the hard disk array.
