Engineering Contradiction Analysis
1Ease of operation
If a universal interface implementation is used to process requests across multiple storage systems, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A performance monitor is introduced as an intermediary component that sits between the application and multiple storage systems. The performance monitor receives requests, routes them through the common interface implementation to appropriate storage systems, and returns responses. This mediator handles the complexity of interfacing with diverse storage systems while presenting a unified, simple interface to applications, thereby improving ease of operation without exposing the underlying device complexity.
Solution Approach 2:
The performance monitor is designed with multi-functionality to handle various storage system types (relational databases, file systems, caches, cloud-based storage) through a single universal interface implementation. This universal component can process different classes of requests (data retrieval, data modification, metadata operations) across heterogeneous storage systems, reducing the need for multiple specialized interfaces and simplifying application operations while managing the inherent complexity through consolidation.
2Measurement precision
If performance monitoring for multiple classes of requests is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The performance monitoring functionality is segmented into distinct components within the performance monitor: request classification logic that identifies different classes of requests, separate monitoring mechanisms for each request class, and independent performance metric collection for each storage system. This segmentation allows precise measurement of different request types (data retrieval, data modification, metadata operations) while organizing the complexity into manageable, modular segments rather than a monolithic complex system.
Solution Approach 2:
The performance monitor dynamically changes monitoring parameters based on request class and storage system type. Different performance metrics are monitored for different request classes (e.g., response time for data retrieval, throughput for data modification), and the monitoring intensity and parameters are adjusted according to the specific storage system being accessed. This parameter adaptation enables precise measurement tailored to each scenario while avoiding the complexity of uniformly monitoring all parameters for all systems.
3Reliability
If multiple storage systems are evaluated based on performance criteria, then reliability is improved, but loss of time increases
Solution Approach 1:
The performance monitor continuously and proactively monitors performance metrics of multiple storage systems in the background before applications need to make selection decisions. Performance data for different request classes is collected, analyzed, and stored in advance, creating a pre-evaluated performance profile for each storage system. When applications need to select or evaluate storage systems, this preliminary monitoring data is already available, enabling reliable decision-making without time-consuming real-time evaluation.
Solution Approach 2:
The performance monitor implements continuous feedback loops where performance metrics from multiple storage systems are constantly measured, compared, and used to update performance profiles. This feedback mechanism provides applications with up-to-date reliability information about different storage systems based on actual performance data rather than static specifications. The feedback enables reliable storage system selection while minimizing time loss by providing current performance insights without requiring exhaustive real-time testing.
