| 2 | Ceph Storage Cluster | |
| 3 | ====================== | |

| 5 | The :term:`Ceph Storage Cluster` is the foundation for all Ceph deployments. | |
| 6 | Based upon :abbr:`RADOS (Reliable Autonomic Distributed Object Store)`, Ceph | |
| 7 | Storage Clusters consist of two types of daemons: a :term:`Ceph OSD Daemon` | |
| 8 | (OSD) stores data as objects on a storage node; and a :term:`Ceph Monitor` (MON) | |
| 9 | maintains a master copy of the cluster map. A Ceph Storage Cluster may contain | |
| 10 | thousands of storage nodes. A minimal system will have at least one | |
| 11 | Ceph Monitor and two Ceph OSD Daemons for data replication. | |
| 12 | ||
| 13 | The Ceph Filesystem, Ceph Object Storage and Ceph Block Devices read data from | |
| 14 | and write data to the Ceph Storage Cluster. | |

| 20 | ||
| 21 | Ceph Storage Clusters have a few required settings, but most configuration | |
| 22 | settings have default values. A typical deployment uses a deployment tool | |
| 23 | to define a cluster and bootstrap a monitor. See `Deployment`_ for details | |
| 24 | on ``ceph-deploy.`` | |

| 35 | ||
| 36 | Once you have a deployed a Ceph Storage Cluster, you may begin operating | |
| 37 | your cluster. | |

| 59 | ||
| 60 | Most Ceph deployments use `Ceph Block Devices`_, `Ceph Object Storage`_ and/or the | |
| 61 | `Ceph Filesystem`_. You may also develop applications that talk directly to | |
| 62 | the Ceph Storage Cluster. | |
