One-click disaster recovery switchover supported by the OceanStor ReplicationDirector

The OceanStor ReplicationDirector (mainstream version: V100R003C10) supports one-click disaster recovery switchovers.
The OceanStor ReplicationDirector supports two service switchover modes: planned migration and failover. The two modes significantly simplify disaster recovery switchovers, prevent misoperations in manual switchovers, and minimize recovery time objective (RTO).
1. One-click planned migration
A planned migration is performed when data or applications at the production site need to be switched to the disaster recovery site due to a non-disaster cause, such as a power failure, an upgrade, or maintenance.
2. One-click failover
A failover is performed when data or applications at the production site become unavailable due to a disaster or fault.
