In this chapter, you learned:
Red Hat Ceph Storage can provide a unified storage back end for OpenStack services that consume block, image, object, and file-based storage.
OpenStack Glance can use Ceph RBD images to store the operating system images that it manages.
OpenStack Cinder can also use RADOS block devices to provide block-based storage for virtual machines that run as cloud instances.
The RADOS Gateway can replace the native OpenStack Swift storage by providing object storage for applications that use the OpenStack Swift API, and integrates its user authentication with OpenStack Keystone.
Red Hat OpenShift Data Foundation is an operator bundle that provides cloud storage and data services to Red Hat OpenShift Container Platform; it is composed of the ocs-storage, NooBaa, and Rook-Ceph operators.
Rook-Ceph is a cloud storage orchestrator that installs, monitors, and manages the underlying Ceph cluster in the OpenShift Data Foundation bundle operator. Rook-Ceph provides the required drivers to request storage to the cluster.
PersistentVolumeClaims are an OpenShift resource type that represent a request for a storage object. They contain the StorageClass which describes the PersistentVolume that should bind to it.
Access modes describe the mount capabilities of a PersistentVolume on pods.
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
