Sage Weil, the creator of Ceph, recently gave a talk at linux conf au. The slides [1] mostly stand on their own. The first two slides address your first question. The remainder of the slides are a deeper dive into the technical aspects of the system than TFA gives. I am not using Ceph but my company makes a system built on an extremely similar architecture and I can vouch for the scalability (modulo implementation stupidities, natch). That being said, our system is difficult to administer due to all the moving parts and its distributed nature - I don't know if Ceph shares this drawback.
