Dynamic Configuration Validation for Multi-Host Off-Cluster Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network data storage systems face challenges in efficiently managing virus scans across multiple third-party antivirus scanners, leading to unnecessary rescanning of data and performance hits due to the lack of dynamic configuration management.
Innovation Solution
Implementing a dynamic configuration validation service that maintains a list of valid scanner versions and uses unique scanner version IDs to determine if files need rescanning, thereby reducing unnecessary rescanning and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic configuration management is implemented to track scanner versions, then unnecessary rescanning is reduced and performance improves, but system complexity increases due to version tracking mechanisms
Solution Approach 1:
The system performs preliminary actions by maintaining a version table that tracks scanner version IDs before scanning operations occur. When a scanner connects or updates, its version ID is recorded in advance, allowing the system to quickly determine during file access whether rescanning is necessary without performing full scans unnecessarily.
Solution Approach 2:
A version table acts as an intermediary data structure between the scanner service and the file access operations. This table stores scanner version IDs and serves as a reference mechanism that mediates between scanner updates and file scanning decisions, eliminating the need for complex direct communication protocols between scanners and file access requests.
2Adaptability or versatility
If multiple third-party antivirus scanners are supported to allow vendor competition, then system versatility improves, but coordination difficulty increases leading to performance hits
Solution Approach 1:
The version table mechanism serves multiple functions: it tracks scanner connections, records version IDs, determines rescanning needs, and coordinates between multiple scanners. This universal approach works with any third-party antivirus scanner regardless of vendor, providing multi-vendor support through a single coordinated system.
Solution Approach 2:
The system uses scanner version ID as a key parameter to track and coordinate scanner states. By monitoring changes in version ID parameters when scanners update or reconnect, the system automatically adjusts its scanning coordination without requiring complex vendor-specific protocols or manual configuration.
3Reliability
If file access operations check scanner availability to determine rescanning, then scanning accuracy improves, but operation time increases due to additional verification steps
Solution Approach 1:
Scanner version information is recorded in advance in the version table when scanners connect or update. This preliminary tracking eliminates the need for time-consuming verification steps during file access operations, as the system can immediately check the version table to determine if rescanning is needed.
Solution Approach 2:
Instead of performing complex real-time verification of scanner availability during file access, the system uses a simplified copy mechanism by checking the pre-recorded version ID in the version table. This copying approach provides sufficient accuracy for determining scan status without the time overhead of full verification protocols.
