This reference architecture describes how to deploy Red Hat OpenStack Platform 10 and Red Hat Ceph Storage 2 in a way that both the OpenStack Nova Compute services and the Ceph Object Storage Daemon (OSD) services reside on the same node. A server which runs both compute and storage processes is known as a hyper-converged node. There is increasing interest in the field for hyper-convergence for cloud (NFVi and Enterprise) deployments. The reasons include smaller initial deployment foot prints, a lower cost of entry, and maximized capacity utilization.
