4.6. Hub recovery support for co-situated and neutral site deployments
The Metropolitan and Regional disaster recovery solutions of OpenShift Data Foundation now support neutral site deployments and hub recovery of co-situated managed clusters using Red Hat Advanced Cluster Management. For configuring hub recovery setup, a 4th cluster is required which acts as the passive hub.
The passive hub cluster can be set up in either one of the following ways:
- The primary managed cluster (Site-1) can be co-situated with the active RHACM hub cluster while the passive hub cluster is situated along with the secondary managed cluster (Site-2).
- The active RHACM hub cluster can be placed in a neutral site (Site-3) that is not impacted by the failures of either of the primary managed cluster at Site-1 or the secondary cluster at Site-2. In this situation, if a passive hub cluster is used it can be placed with the secondary cluster at Site-2.
For more information, see respective Metro-DR and Regional-DR chapters on Hub recovery using Red Hat Advanced Cluster Management.
