STORAGE SYSTEM, MEMORY MANAGEMENT METHOD, AND MANAGEMENT NODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094936 titled 'STORAGE SYSTEM, MEMORY MANAGEMENT METHOD, AND MANAGEMENT NODE
Simplified Explanation
The storage system described in the patent application includes multiple storage nodes, each consisting of a first storage device of a higher performance level and a second storage device of a lower performance level. The system also includes a global 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 - Global 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 requiring tiered storage based on access frequency - Systems needing dynamic data migration for performance optimization
- Problems solved by this technology:
- Efficient data storage management based on access frequency - Improved performance by utilizing storage devices with different performance levels
- Benefits of this technology:
- Optimal use of storage resources - Enhanced system performance through data tiering and migration
- Potential commercial applications of this technology:
- Cloud storage services - Big data analytics platforms
- Possible prior art:
- Tiered storage systems in data centers - Cache management techniques in storage systems
- Unanswered Questions:
- How does the management node determine the threshold for migrating data between tiers?
- Unanswered Questions:
The patent application does not specify the exact method used by the management node to set the threshold for data migration based on access frequency.
- What mechanisms are in place to ensure data integrity during the migration process?
The patent application does not detail the specific measures taken to maintain data integrity when migrating data between storage tiers.
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.
