RADOS Object Store
|
|
====================
|
|
|
|
Ceph's :abbr:`RADOS (Reliable Autonomic Distributed Object Store)` Object Store
|
|
is the foundation for all Ceph clusters. When you use object store clients such
|
|
as the CephFS filesystem, the RESTful Gateway or Ceph block devices, Ceph reads
|
|
data from and writes data to the object store. Ceph's RADOS Object Stores
|
|
consist of two types of daemons: Object Storage Daemons (OSDs) store data as
|
|
objects on storage nodes; and Monitors maintain a master copy of the cluster
|
|
map. A Ceph cluster may contain thousands of storage nodes. A minimal system
|
|
will have at least two OSDs for data replication.

|
|
|
|
Once you have installed Ceph packages, you must configure. There are a a few
|
|
required settings, but most configuration settings have default values.
|
|
Following the initial configuration, you must deploy Ceph. Deployment consists
|
|
of creating and initializing data directories, keys, etc.

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

</td><td><h3>APIs</h3>
|
|
|
|
Most Ceph deployments use Ceph `block devices`_, the `gateway`_ and/or the
|
|
`CephFS filesystem`_. You may also develop applications that talk directly to
|
|
the Ceph object store.
