Regional-DR [Technology Preview]
Regional disaster recovery (Regional-DR) is composed of Red Hat Advanced Cluster Management for Kubernetes (RHACM) and IBM Storage Fusion Data Foundation components to provide application and data mobility across OpenShift Container Platform clusters. It is built on Asynchronous data replication and hence could have a potential data loss but provides the protection against a broad set of failures.
Enable pools for mirroring.
Automatically mirror images across RBD pools.
Provides csi-addons to manage per Persistent Volume Claim mirroring.
Regional-DR supports Multi-Cluster configuration that is deployed across different regions and data centers. For example, a 2-way replication across two managed clusters located in two different regions or data centers. This solution is entitled with Red Hat Advanced Cluster Management (RHACM) and Fusion Data Foundation Advanced SKUs and related bundles.
Disaster Recovery features supported by Fusion Data Foundation require the following prerequisite in order to successfully implement a Disaster Recovery solution:
- Fusion subscription should be active on both source and destination clusters.
