Application: Unified storage and method of controlling unified storage (Patent ID: US20240104064A1)

The patent filed by Hitachi Ltd. describes a unified storage system that combines block storage and file storage functionalities to maintain availability and scale out file performance while minimizing costs. The system includes multiple controllers equipped with main processors and channel adapters, where each main processor runs a block storage control program to process data, and each channel adapter cooperates to operate a distributed file system and distributively store data across the controllers. The system also allows for redundancy by requesting multiple controllers to store data and can handle failures by transferring processing to a different controller and using redundantly stored data to restore operations.

Furthermore, the patent details a method for controlling the unified storage system, outlining the process by which main processors and channel adapters in the controllers work together to operate the distributed file system and store data across the controllers. The system's design allows for efficient data storage and retrieval, with mechanisms in place to ensure redundancy and failover capabilities in case of controller failures. Additionally, the system can determine optimal data storage destinations based on storage requests, selecting appropriate controllers and channel adapters to handle the data effectively. Overall, the patented technology offers a cost-effective solution for maintaining high availability and performance in file storage systems.
