Storage can be either provisioned from dedicated nodes or shared with compute services. Provisioning occurs on disk drives that are locally attached to servers that have been added as compute nodes to the cluster.
The Red Hat Data Services portfolio of solutions includes persistent software-defined storage (SDS) and data services that are integrated with and optimized for OpenShift Container Platform. As part of the portfolio, Red Hat OpenShift Data Foundation (formerly known as OpenShift Container Storage) delivers resilient and persistent SDS and data services that are based on Ceph, Rook, and NooBaa technologies.
Running as a Kubernetes service, OpenShift Data Foundation is engineered, tested, and certified to provide data services for OpenShift Container Platform on any infrastructure. OpenShift Data Foundation can be deployed within an OpenShift Container Platform cluster on existing worker nodes, infrastructure nodes, or dedicated nodes. Alternatively, OpenShift Data Foundation can be decoupled and managed as a separate, independently scalable data store, delivering data for one or many OpenShift Container Platform clusters. It is also possible to use existing compute nodes if they meet OpenShift Data Foundation hardware requirements.
You can start the deployment of OpenShift Data Foundation from the embedded Operator Hub when you are logged into OpenShift Container Platform as the cluster administrator. For more information, see OpenShift Data Foundation.
