| 5 | Ceph can run with a cluster containing thousands of Object Storage Devices | |
| 6 | (OSDs). A minimal system will have at least two OSDs for data replication. To | |
| 7 | configure OSD clusters, you must provide settings in the configuration file. | |
| 8 | Ceph provides default values for many settings, which you can override in the | |
| 9 | configuration file. Additionally, you can make runtime modification to the | |
| 10 | configuration using command-line utilities. | |
| 11 | ||
| 12 | When Ceph starts, it activates three daemons: | |
| 13 | ||
| 14 | - ``ceph-mon`` (mandatory) | |
| 15 | - ``ceph-osd`` (mandatory) | |
| 16 | - ``ceph-mds`` (mandatory for cephfs only) | |
| 17 | ||
| 18 | Each process, daemon or utility loads the host's configuration file. A process | |
| 19 | may have information about more than one daemon instance (*i.e.,* multiple | |
| 20 | contexts). A daemon or utility only has information about a single daemon | |
| 21 | instance (a single context). | |
| 22 | ||
| 23 | .. note:: Ceph can run on a single host for evaluation purposes. | |
