Overview
Prior to the installation, you must assign the roles to the machines of the cluster. The possible roles are : MON, MDS, OSD, and DEPLOY. You need at least one MON machine, but to avoid bottlenecks when the number of OSD increases, it's better to have 3 MON machines (always have an odd number of MON machines to be able to have a quorum). The MDS is only needed if you want to use CephFS. The OSD daemons will run on machines that will contains the storage disks.
The layout and the parameters of the cluster are described in the template site/ceph.
