TECHNIQUES FOR OPTIMIZED DATA RESYNCHRONIZATION BETWEEN REPLICATION SITES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240311033 titled 'TECHNIQUES FOR OPTIMIZED DATA RESYNCHRONIZATION BETWEEN REPLICATION SITES
The abstract describes techniques for resynchronizing storage resources of two sites configured for synchronous replication in the event of a failure or fracture of the replication process. This involves tracking in-progress write requests in a map and using them, along with resource snapshots and differences, to resynchronize the impacted resources.
- Tracking in-progress write requests in a map to facilitate resynchronization of storage resources in synchronous replication configurations.
- Utilizing resource snapshots and snapshot differences in combination with in-progress write requests to achieve resynchronization.
- Potential configurations include active paths between both sites and a host, as well as bidirectional or two-way synchronous replication between the sites.
- In case of a failure or fracture in synchronous replication, processing is performed to resynchronize the impacted resources of the two sites.
- Active and passive paths can be used between the host and the two sites in the synchronous replication configuration.
Potential Applications: - Data centers - Disaster recovery solutions - High availability systems
Problems Solved: - Ensuring data consistency between geographically dispersed sites - Minimizing data loss in case of failures - Maintaining high availability of critical systems
Benefits: - Improved data protection - Enhanced disaster recovery capabilities - Increased system reliability
Commercial Applications: Title: Data Resynchronization Technology for Disaster Recovery Solutions This technology can be applied in data centers, financial institutions, and any organization requiring high availability and data protection.
Questions about Data Resynchronization Technology: 1. How does this technology improve disaster recovery solutions? This technology enhances disaster recovery solutions by ensuring data consistency and minimizing data loss in case of failures.
2. What are the key features of this resynchronization process? The key features include tracking write requests, using resource snapshots, and differences to resynchronize storage resources in synchronous replication configurations.
Original Abstract Submitted
techniques for resynchronizing storage resources of two sites configured for synchronous replication can include tracking in-progress write requests in a map. responsive to a site failure or a replication link failure resulting in failure or fracture of the synchronous replication, processing can be performed to resynchronize impacted resources of the two sites configured for synchronous replication. the processing can use the in-progress write requests in combination with resource snapshots and snapshot differences to resynchronize the impacted resource of the two sites. in at least one embodiment, the synchronous replication configuration can include active paths between both sites and a host. in at least one embodiment, the synchronous replication configuration can include an active path between the host and one site, and a passive path between the host and the second site. the synchronous replication can be bidirectional or two-way synchronous replication between the two sites.
