One cephfs filesystem, one directory per project, quotas in cephfs, exported via NFS ganesha. Unless you have lots of really small files, then you might want to consider RBD (where HA is more annoying to handle). Paul Am Mo., 8.

But how could I make different project (nfsA nfsB nfsC) 'see' or 'mount' part of the total 200TB capacity, there should be many small cephfs(es) and each one has it's own given smaller capacity. > > Rados?
