ceph (Ceph Storage Monitoring)
Ceph is a unified, distributed storage system designed for excellent performance, reliability and scalability.
Ceph Storage Clusters consist of two types of daemons: a Ceph OSD Daemon (OSD) stores data as objects on a storage node; and a Ceph Monitor (MON) maintains a master copy of the cluster map. A Ceph Storage Cluster may contain thousands of storage nodes. A minimal system will have at least one Ceph Monitor and two Ceph OSD Daemons for data replication.
