Preface
To scale the storage capacity of OpenShift Container Storage in internal mode, you can do either of the following:
- Scale up storage nodes - Add storage capacity to the existing Red Hat OpenShift Container Storage worker nodes
- Scale out storage nodes - Add new worker nodes containing storage capacity
For scaling your storage in external mode, see Red Hat Ceph Storage documentation.
