Anyone using ceph on multi petabyte data stores?
For example, a cluster of 12 systems with a combined storage of 2.3P.

I don't think so

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.

You can also put ceph-osd daemons in front of large disk arrays, but that
is a configuration we have less experience with to date. That being the
case, some users are actively evaluating that now, so we'll know soon how
well it works out...
