Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data center systems face limitations in operating speed due to the response times of cache and database servers, which affect overall data center performance.
Innovation Solution
A server device is designed with multiple interface circuits for network communication, independent memory modules, and a switch circuit that selects the appropriate memory module based on data chunk attributes, enabling efficient data processing and management through a data plane and control plane circuit configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple memory modules are used to increase data processing capacity, then productivity is improved, but device complexity increases due to the need for switch circuit and routing management
Solution Approach 1:
The system segments memory management by dividing memory modules into different types (first memory modules for hot data, second memory modules for cold data) and uses a switch circuit to route data chunks to appropriate memory modules based on their access patterns and attributes, thereby managing complexity through structured segmentation
Solution Approach 2:
The switch circuit acts as an intermediary component that receives data chunks from interface circuits and intelligently routes them to the most appropriate memory module based on attributes such as access frequency and data type, thereby managing the complexity of multiple memory modules through a centralized routing mechanism
2Speed
If data is stored in cache server to improve response speed, then speed is improved, but loss of time occurs due to cache miss and data retrieval from database server
Solution Approach 1:
The system applies local quality by storing different types of data in different memory modules based on their access characteristics - hot data (frequently accessed) is stored in first memory modules for fast access, while cold data (infrequently accessed) is stored in second memory modules, thereby optimizing response speed for different data access patterns
Solution Approach 2:
The system performs preliminary action by proactively caching frequently accessed data in the cache server's memory modules before it is actually needed, based on access pattern analysis and prediction, thereby reducing cache miss rates and avoiding time-consuming data retrieval from database servers
3Reliability
If database server processes all data requests to ensure data accuracy, then reliability is improved, but productivity decreases due to processing bottleneck
Solution Approach 1:
The system segments data into hot data and cold data categories, and segments processing responsibilities between cache server (for hot data) and database server (for cold data), thereby maintaining data accuracy through proper data classification while improving overall processing throughput by distributing workloads appropriately
