1Productivity

If data replication is performed without port utilization assessment, then replication can start immediately, but port overload occurs leading to increased latency and performance degradation

Engineering Contradiction:

Improvedata replication speedVSAvoidstorage system performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary assessment of port utilization by generating utilization vectors that capture historical port usage patterns before assigning ports to data replication tasks. This advance evaluation ensures ports are selected based on their capacity and usage characteristics, preventing overload while maintaining efficient replication.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors and updates port utilization vectors based on actual port usage during replication operations. This feedback mechanism allows the system to learn from past performance and make better port selection decisions for future replication tasks, dynamically optimizing performance.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If multiple ports are available for data replication, then port selection flexibility increases, but selecting the optimal port becomes more complex

Engineering Contradiction:

Improveport selection flexibilityVSAvoidport selection process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically generates utilization vectors and performs port selection without manual intervention. The port selection process is autonomous, with the system evaluating multiple ports based on their utilization characteristics and selecting the optimal pair automatically, reducing operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system transforms port selection from a qualitative decision process to a quantitative parameter-based evaluation. By representing port usage as utilization vectors with numerical values, the system can objectively compare ports and select optimal pairs based on measurable criteria rather than subjective judgment.

Inventive Principle:

Principle #35Parameter changes
