Chapter 2. New Features
This section describes new features introduced in Red Hat OpenShift Data Foundation 4.12.
2.1. General availability of Metropolitan disaster recovery (Metro-DR) solution
The Metro-DR feature with Red Hat Advanced Cluster Management for Kubernetes 2.7 is now General Available from Red Hat OpenShift Data Foundation version 4.12.1 and higher.
Metro-DR solution ensures protection and business continuity during the unavailability of a data center with no data loss while using multiple clusters synchronous replication. In the public cloud these are similar to protecting from an Availability Zone failure. This solution offers quick recovery of Applications with no data loss.
For more information, see the planning guide and Metro-DR solution for OpenShift Data Foundation guide.
2.2. General availability of logical volume manager storage for single node OpenShift clusters
Logical volume manager storage provides dynamic block storage for the single node OpenShift clusters where resource constraints are more important than feature variety and data resilience. One target application is for Radio Access Networks (RAN) in the Telecommunications market. For more information, see Installing LVM Storage using RHACM.
In previous versions, the product was named OpenShift Data Foundation - Logical Volume Manager. With general availability, it has been renamed to logical volume manager storage (LVM Storage or LVMS).
Starting with this release, in addition to dynamic storage, logical volume manager storage provides the following new features:
- Provides the ability to control or restrict the volume group to your preferred disks by enabling you to manually select the local paths of the disks by path or by name. For more information, see Installing the OpenShift Data Foundation Logical Volume Manager Operator using RHACM.
- Provides the ability to install and use logical volume manager storage on single node OpenShift clusters with additional worker nodes. This helps you to use logical volume manager storage on your desired single node OpenShift architecture. For more information, see Installing the OpenShift Data Foundation Logical Volume Manager Operator using RHACM and Scaling storage of Single Node OpenShift cluster.
