TECHNIQUES FOR AVOIDING AND REDUCING DATA UNAVAILABILITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240126648 titled 'TECHNIQUES FOR AVOIDING AND REDUCING DATA UNAVAILABILITY
Simplified Explanation
The patent application describes a clustered pair of storage systems configured for active-active bidirectional synchronous replication, where a stretched volume is exposed over paths to both systems, allowing for replicated writes between the systems. The cluster can use a time-to-live mechanism to ensure system health and avoid data unavailability.
- Stretched volume configuration for active-active bidirectional synchronous replication
- Time-to-live mechanism for system health assessment and data availability
- Polarization algorithms to handle unhealthy systems and ensure data replication
- Improved polarization technique using a witness system
- Control component to detect and disable unhealthy systems
Potential Applications
This technology can be applied in disaster recovery solutions, high availability systems, and data replication for critical business operations.
Problems Solved
This technology addresses the challenges of system health monitoring, data availability, and failover management in clustered storage systems.
Benefits
The benefits of this technology include improved system reliability, reduced data unavailability, and enhanced disaster recovery capabilities.
Potential Commercial Applications
Commercial applications of this technology include enterprise storage solutions, cloud storage services, and data replication software for businesses.
Possible Prior Art
One possible prior art could be traditional storage replication techniques that may not offer the same level of bidirectional synchronous replication and system health monitoring as described in this patent application.
What is the impact of this technology on data replication in clustered storage systems?
This technology significantly enhances data replication in clustered storage systems by providing active-active bidirectional synchronous replication, ensuring data consistency and availability across multiple storage systems.
How does the time-to-live mechanism improve system health in clustered storage environments?
The time-to-live mechanism continuously assesses the health of systems in the cluster and allows for the detection and mitigation of unhealthy systems, thereby improving overall system reliability and data availability.
Original Abstract Submitted
a clustered pair of storage systems configured for active-active bidirectional synchronous replication expose a stretched volume over paths to both storage systems. writes to the stretched volume received at each system are replicated to the peer system. the cluster can use a time-to-live (ttl) mechanism by which a non-preferred system continuously requests a ttl grant from the preferred system to remain in the cluster. algorithms that reduce or avoid data unavailability are described and can include assessing the health of the systems in the cluster. an unhealthy system can trigger a one-sided polarization algorithm to notify the peer system that it is polarization winner. an improved polarization technique using a witness to decide the polarization winner includes a system adding a time delay before contacting the witness if the system is unhealthy. a control component can detect an unhealthy system and disable the active-active bidirectional synchronous replication.
