Regional-DR deployment workflow

This section provides an overview of the steps required to configure and deploy Regional-DR capabilities using the latest versions of IBM Storage Fusion Data Foundation across two distinct OpenShift Container Platform clusters. In addition to two managed clusters, a third OpenShift Container Platform cluster will be required to deploy the Red Hat Advanced Cluster Management (RHACM).

To configure your infrastructure, perform the following steps:

1. Ensure requirements across the Hub, Primary and Secondary Openshift Container Platform clusters that are part of the DR solution are met.
   See Requirements for enabling Regional-DR.
2. Install Fusion Data Foundation operator and create a storage system on Primary and Secondary-managed clusters.
   See Creating an Fusion Data Foundation cluster on managed clusters.
3. Install the ODF Multicluster Orchestrator on the Hub cluster.
   See Installing Fusion Data Foundation Multicluster Orchestrator operator.
4. Configure SSL access between the Hub, Primary and Secondary clusters.
   See Configuring SSL access across clusters.
5. Create a DRPolicy resource for use with applications requiring DR protection across the Primary and Secondary clusters.
   See Creating Disaster Recovery Policy on Hub cluster.

   Note: There can be more than a single policy.
6. Testing your disaster recovery solution with:
   1. Subscription-based application:
      • Create sample applications. See Creating a sample subscription-based application.
      • Test failover and relocate operations using the sample application between managed clusters. See Subscription-based application failover between managed clusters and Relocating Subscription-based application between managed clusters.
   2. ApplicationSet-based application:
      • Create sample applications. See Creating ApplicationSet-based applications.
      • Test failover and relocate operations using the sample application between managed clusters. See ApplicationSet-based application failover between managed clusters and Relocating an ApplicationSet-based application between managed clusters.
