STORAGE SYSTEM, MEMORY MANAGEMENT METHOD, AND MANAGEMENT NODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18527353 titled 'STORAGE SYSTEM, MEMORY MANAGEMENT METHOD, AND MANAGEMENT NODE
Simplified Explanation
The storage system described in the patent application includes multiple storage nodes, each with a first storage device of a higher performance level and a second storage device of a lower performance level. The system also includes a globe cache with a first tier for high-access frequency data and a second tier for low-access frequency data. The management node monitors the access frequency of data in the first tier and instructs storage nodes to migrate data to the second tier when the access frequency falls below a threshold.
- Explanation of the patent:
- Multiple storage nodes with different performance levels - Globe cache with two tiers for data storage based on access frequency - Management node monitors and manages data migration between tiers based on access frequency
Potential applications of this technology: - Data storage systems in cloud computing environments - Content delivery networks - Big data analytics platforms
Problems solved by this technology: - Efficient data storage management based on access frequency - Optimization of storage resources for better performance
Benefits of this technology: - Improved data access speed for frequently accessed data - Cost-effective storage management - Enhanced overall system performance
Potential commercial applications of this technology: - Cloud storage service providers - Data center management companies - Enterprise storage solutions
Possible prior art: - Tiered storage systems in data centers - Cache management techniques in distributed systems
Unanswered questions: 1. How does the system handle data migration between storage nodes? 2. What is the impact of data migration on overall system performance?
Original Abstract Submitted
A storage system includes multiple storage nodes. Each storage node includes a first storage device of a first type and a second storage device of a second type, and a performance level of the first storage device is higher than the second storage device. The globe cache includes a first tier comprising the first storage device in each storage node, and a second tier comprising the second storage device in each storage node. The first tier is for storing data with a high access frequency, and the second tier is for storing data with a low access frequency. The management node monitors an access frequency of target data stored in the first tier. When the access frequency of the target data is lower than a threshold, the management node instructs the first storage node to migrate the target data from the first tier to the second tier.
