Ceph¶
Ceph monitors use their node host networks to interact with Ceph daemons. Ceph daemons communicate with each other over a specified cluster network and provide endpoints over the public network.
The messenger V2 (msgr2) or earlier V1 (msgr) protocols are used for
communication between Ceph daemons.
