This section describes the characteristics, DR technologies, and principles of the geo-redundant DR solution.
Solution Introduction
This solution establishes a same-city DR center and a remote DR center. It uses the remote DR center to recover services if the production center fails due to a disaster or misoperation, ensuring business continuity.
HyperMetro (SAN) and Asynchronous Replication (SAN) DR Principles
The HyperMetro technology provided by storage devices is used for same-city DR. Remote replication functions provided by storage devices are used to replicate application data from a production data center to a DR center for remote DR.
