INTEGRATING MIRRORED STORAGE TO REMOTE REPLICATION SITE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17822181 titled 'INTEGRATING MIRRORED STORAGE TO REMOTE REPLICATION SITE

Simplified Explanation

- A computer system is described that transmits a query command to a storage descriptor area of a first disk in a dual-site data replication system. - The dual-site data replication system provides active-active access to a volume of data stored in an active disk and replicated in a backup disk. - The computer receives a response to the query command, indicating the active disk and the backup disk for the system. - The computer controls an additional copy of the data volume at a further remote site based on the active disk.

Potential Applications

- Disaster recovery solutions - Data backup and redundancy systems - High availability systems for critical data

Problems Solved

- Minimizing data loss in case of disk failure - Ensuring data availability in case of site failure - Efficient management of data replication across multiple sites

Benefits

- Improved data reliability and availability - Enhanced disaster recovery capabilities - Simplified data management across multiple sites


Original Abstract Submitted

A method, computer system, and computer program product area provided. A computer transmits a query command to a storage descriptor area of a first disk. The first disk belongs to a dual-site data replication system. The dual-site data replication system provides active-active access to a volume of data stored in an active disk and replicated in a backup disk. The computer receives a response to the query command. The response indicates the active disk and the backup disk for the dual-site data replication system. The computer controls an additional copy of the volume of data at a further remote site based on the active disk.
