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 several types of daemons:
|
|
|
|
|
|
|
|
|
|
1. a :term:`Ceph OSD Daemon` (OSD) stores data as objects on a storage node
|
|
|
|
|
2. a :term:`Ceph Monitor` (MON) maintains a master copy of the cluster map.
|
|
|
|
|
3. a :term:`Ceph Manager` manager daemon
|
|
|
|
|
|
|
|
|
|
A Ceph Storage Cluster might contain thousands of storage nodes. A
|
|
|
|
|
minimal system has at least one Ceph Monitor and two Ceph OSD
|
|
|
|
|
Daemons for data replication.

The Ceph File System, Ceph Object Storage and Ceph Block Devices read data from

and write data to the Ceph Storage Cluster.

<h3>Config and Deploy</h3>

Ceph Storage Clusters have a few required settings, but most configuration
|
|
|
|
|
settings have default values. A typical deployment uses a deployment tool
|
2021-02-18 17:48:30 +00:00
|
|
|
to define a cluster and bootstrap a monitor. See :ref:`cephadm` for details.

Once you have deployed a Ceph Storage Cluster, you may begin operating

|
your cluster.

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