The intent of this solution is to detail the steps and commands necessary to deploy OpenShift Data Foundation along with Kubernetes zone topology labels to achieve a highly available storage infrastructure. It also provides different methods of recovery for applications and their storage.
This is a Technology Preview feature that is currently intended for deployment in the OpenShift Container Platform on-premises and in the same data center. This solution is not recommended for deployments stretching over multiple data centers. Instead, consider Metro-DR as a first option for no data loss DR solution deployed over multiple data centers with low latency networks.
NOTE: High Availability (HA) Stretch cluster is a Technology Preview feature and is subject to Technology Preview support limitations. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
