From the latest Dreamhost newsletter:<p><i>In fact, Ceph is practically what you'd call "stable" at this point
(which is not to say it's "production-ready"!), and we've actually begun
testing it as a backup/replacement for our poor backup.dreamhost.com
server (who's been having a terrible time for months)!<p>If YOU would like to give Ceph a try, please, download away... it's free!<p>Also, we're going to be setting up a "playground" test-bed where anybody
can try out a Ceph installation we set up and maintain in our data
center. If you're interested, just email beta@ceph.newdream.net, and
we'll send you an invitation when it's ready!</i><p>[edit: added the bit about beta testing]
