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.

Important: Technology Preview features are not supported with IBM production service level agreements (SLAs), might not be functionally complete, and IBM does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
Fusion Data Foundation is backed by Ceph as the storage provider, whose lifecycle is managed by Rook and it is enhanced with the ability to:
  • 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.

Prerequisites

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.
