INFORMATION PROCESSING SYSTEM AND INFORMATION PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18119414 titled 'INFORMATION PROCESSING SYSTEM AND INFORMATION PROCESSING METHOD
Simplified Explanation: The patent application describes a system and method for processing information that can withstand failures in different sites. It involves forming a redundancy group with multiple storage controllers in different sites, including an active controller processing data and a standby controller taking over if the active one fails.
- Redundancy group formed with multiple storage controllers in different sites
- Active controller processes data, standby controller takes over in case of failure
- Active controller stores data from host application in the same site's storage device
- Redundant data stored in another site's storage device for data restoration
Key Features and Innovation:
- Highly available information processing system
- Redundancy group with active and standby storage controllers
- Data processing and storage across different sites for fault tolerance
Potential Applications: This technology can be applied in critical systems where continuous availability of data is essential, such as financial institutions, healthcare facilities, and telecommunications networks.
Problems Solved:
- Ensuring data availability in the event of failures
- Reducing downtime and data loss
- Improving system reliability and fault tolerance
Benefits:
- Increased system reliability and availability
- Minimized data loss and downtime
- Enhanced fault tolerance and disaster recovery capabilities
Commercial Applications: The technology can be utilized in industries where uninterrupted data processing is crucial, such as banking, healthcare, and emergency services. It can also benefit cloud service providers and data centers.
Prior Art: Readers interested in prior art related to this technology can explore existing patents in the field of fault-tolerant information processing systems and data redundancy techniques.
Frequently Updated Research: Researchers may find relevant studies on fault-tolerant systems, data replication, and disaster recovery strategies that could complement and enhance the technology described in the patent application.
Questions about the Technology: 1. How does the redundancy group ensure data consistency across different sites? 2. What measures are in place to prevent data corruption during failover processes?
Original Abstract Submitted
Proposed are a highly available information processing system and information processing method capable of withstanding a failure in units of sites. A redundancy group including a plurality of the storage controllers installed in different sites is formed, and the redundancy group includes an active state storage controller which processes data, and a standby state storage controller which takes over processing of the data if a failure occurs in the active state storage controller, and the active state storage controller executes processing of storing the data from a host application installed in the same site in the storage device installed in that site, and storing redundant data for restoring data stored in a storage device of a same site in the storage device installed in another site where a standby state storage controller of a same redundancy group is installed.
