Chapter 4. Technology previews

This section describes technology preview features introduced in Red Hat OpenShift Container Storage 4.6.

Red Hat Virtualization technology preview support

OpenShift Container Storage can now be installed and managed using Red Hat Virtualization. For more information see, the Deploying and managing OpenShift Container Storage using Red Hat Virtualization guide.

Red Hat OpenStack Platform technology preview support

OpenShift Container Storage can now be installed and managed using Red Hat OpenStack Platform. For more information see, the Deploying and managing OpenShift Container Storage using Red Hat OpenStack Platform guide.

IBM Power Systems technology preview support

OpenShift Container Storage can now be installed and managed using IBM Power Systems. For more information see, the Deploying and managing OpenShift Container Storage using IBM Power Systems Guide.

IBM Z and LinuxONE technology preview support

OpenShift Container Storage can now be installed and managed using IBM Z and LinuxONE. For more information see, the Deploying and managing OpenShift Container Storage using IBM Z and LinuxONE.

Minimum deployment technology preview support

OpenShift Container Storage can now be deployed with minimum configuration when the standard deployment resource requirement is not met. For more information, see minimum deployment resource requirements in the Planning Guide.

Compact deployment technology preview support

OpenShift Container Storage can now be installed on a three-node OpenShift compact bare metal cluster, where all the workloads run on three strong master nodes. There are no worker or storage nodes.

For information on how to configure OpenShift Container Platform on a compact bare metal cluster, see Configuring a three-node cluster and Delivering a Three-node Architecture for Edge Deployments.

Expand storage capacity using additional device

Administrators can now scale up storage capacity using storage classes other than the one defined during deployment. First define a new storage class based on an existing storage provider, and select that storage class when you expand your OpenShift Container Storage capacity. See Scaling storage for more information.
