Disaster recovery (DR) can be disabled for a given workload for managed applications and discovered applications through the OpenShift Web Console.

For more information, see Disabling disaster recovery for a disaster recovery enabled application.

Disaster recovery protection can be enabled for cloned and restored RADOS Block Device (RBD) volumes during DR policy creation for Regional-DR.

For more information, see Disaster recovery protection for cloned and restored RBD volumes.

The ODF CLI tool can be used on existing OpenShift deployments with overlapping pod and service CIDR to verify the clusters meet the prerequisites for peering. The tool verifies the two clusters have non-overlapping service and pod Classless Inter-Domain Routing (CIDR).

For more information, see Requirements for enabling Regional-DR.

2.1.4. VM DR protection for cloned volume
Copy link

DR protection is simplified and automatically decouples parent and child so that each one can independently be DR protected. This eliminates the dependency on the parent volume and VM and its DR status.

2.2. VMware vSphere8 support
Copy link

OpenShift Data Foundation supports deployment on VMware vSphere version 8.

Storage class with 2-way replication (replica-2) enables reduction in overhead with CephFS when data resiliency is not a primary concern. The 2-way replication reduces the amount of storage space used and decreases the level of fault tolerance.

For more information, see Using 2-way replication with CephFS.

2.4. Key Rotation for PV encryption
Copy link

Enabling key rotation when using the key management system (KMS) helps to achieve the security common practices that require periodic encryption key rotation.

For more information, see Enabling key rotation when using KMS.

OpenShift Data Foundation on Microsoft Azure platform supports Azure Key Vault for cluster-wide PV encryption. This Key Vault helps to use a local native solution for Azure instead of a third party tool.

For more information, see Creating an OpenShift Data Foundation cluster.

Multicloud Object Gateway credentials can be set manually using the NooBaa CLI commands.

For more information, see Setting Multicloud Object Gateway account credentials using CLI command.

With the OpenShift Data Foundation command line interface (CLI) tool, a Data Foundation environment can be effectively managed and troubleshot from a terminal. A compatible version of the CLI tool can be downloaded from the customer portal.
