OSDs only talk to other OSDs they learn from the monitors. Ceph doesn't use broadcast or multicast in your local network, so it's safe to run multiple Ceph clusters in one subnet/VLAN. Just make sure you use cephx (enabled by default in 0.55) so that you don't accidentally connect to the wrong cluster.
