Disaster recovery

Metro-DR and Regional-DR are disaster recovery solutions supported by IBM Storage Fusion.

Two IBM Storage Fusion HCI Systems can be joined together to form a stretched storage layer. For information about steps to configure this solution, see Metro-DR for IBM Storage Fusion HCI System.
Two IBM Storage Fusion HCI System clusters in a regional DR relationship with asynchronous replication between the two sites. For more information to configure this solution, see Regional Disaster Recovery - a Technical Preview feature.

Note: In disaster recovery, two clusters must be connected to failover and failback applications. If the cluster recovers after the expiry of the client cert, clean and and setup the connection to rejoin the recovered cluster. For the procedure to rejoin, see Reconnecting OpenShift Container Platform cluster.
