Ceph Storage Cluster
|
|
======================
|
|
|
|
The :term:`Ceph Storage Cluster` is the foundation for all Ceph deployments.
|
|
Based upon :abbr:`RADOS (Reliable Autonomic Distributed Object Store)`, Ceph
|
|
Storage Clusters consist of two types of daemons: a :term:`Ceph OSD Daemon`
|
|
(OSD) stores data as objects on a storage node; and a :term:`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.
|
|
|
|
The Ceph Filesystem, Ceph Object Storage and Ceph Block Devices read data from
|
|
and write data to the Ceph Storage Cluster.

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

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

</td><td><h3>APIs</h3>
|
|
|
|
Most Ceph deployments use `Ceph Block Devices`_, `Ceph Object Storage`_ and/or the
|
|
`Ceph Filesystem`_. You may also develop applications that talk directly to
|
|
the Ceph Storage Cluster.
