Ceph

Definition

Ceph is an open-source, software-defined storage platform providing object, block, and file storage in a single unified system. It uses the CRUSH algorithm to distribute data across the cluster without a single point of failure. Ceph is the default storage backend for OpenStack and is increasingly used with Kubernetes via the Rook operator. Key components include monitors (MON), object storage daemons (OSD), and metadata servers (MDS).
