  There are two Ceph daemons that store data on devices:
  
- * **Ceph OSDs** (or Object Storage Daemons) are where most of the
-   data is stored in Ceph.  Generally speaking, each OSD is backed by
-   a single storage device, like a traditional hard disk (HDD) or
-   solid state disk (SSD).  OSDs can also be backed by a combination
-   of devices, like a HDD for most data and an SSD (or partition of an
-   SSD) for some metadata.  The number of OSDs in a cluster is
-   generally a function of how much data will be stored, how big each
-   storage device will be, and the level and type of redundancy
-   (replication or erasure coding).
- * **Ceph Monitor** daemons manage critical cluster state like cluster
-   membership and authentication information.  For smaller clusters a
-   few gigabytes is all that is needed, although for larger clusters
-   the monitor database can reach tens or possibly hundreds of
-   gigabytes.

 -There are two ways that OSDs can manage the data they store.  Starting
 -with the Luminous 12.2.z release, the new default (and recommended) backend is
 -*BlueStore*.  Prior to Luminous, the default (and only option) was
 -*Filestore*.
