Thank you, Paulo.
Metadata = mds, so metadata server should have cpu power.

And if I understand correctly, monitors are the access points to the

I'm not sure what you mean by "access points to the cluster", but the
monitors only provide the cluster map to the client, which then
communicates directly with the OSDs. Quoting the documentation[1]:
"Ceph eliminates the centralized gateway to enable clients to interact
with Ceph OSD Daemons directly. (...) Before Ceph Clients can read or
write data, they must contact a Ceph Monitor to obtain the most recent
copy of the cluster map."
