The document discusses Ceph, an open-source software-defined storage platform commonly used with OpenStack. It provides an overview of Ceph attributes, architecture, components like monitors, OSDs and placement groups, and how it can provide unified storage. New features in the recent Ceph Jewel release are also covered, such as RBD mirroring and RADOS gateway improvements. The presentation aims to establish Ceph as the preferred storage solution ("buddy") for OpenStack deployments.
