What is OpenShift Container Storage?

OpenShift Container Storage is a software-defined storage (SDS) product of Red Hat, which is built by using the open source projects, such as Rook.IO, Ceph, and NooBaa.

Ceph provides file, block and object storage that backs the persistent volumes (PVs), supporting both ReadWriteOnce (RWO) and ReadWriteMany (RWX) PVs. Rook.IO manages and orchestrates the provisioning of persistent volumes and claims while NooBaa provides Multi-Cloud Object Gateway support to enable object federation across multiple cloud environments.
