With 12 systems, you mean 12 servers with a lot of disks? That's roughly
200TB per server.
On that scale I don't think Ceph would work, it would mean you would
need a HUGE amount of CPU and memory on those boxes to run the OSD's.
If you want to scale to 2.3P you should be looking in the direction of
hunderds of small machines all storing a couple of TB.
