Hi Sage I tried Ceph two weeks ago on two hosts (one mds, two osds, two clients), but performance was not so good as I expected. I used dbench. Perhaps the reason was high logging traffic, but I did not try to turn it off. I am going to test it on real world task - kernel building, but sorry, I do not have time to look at it now. My dream is to have a parallel-distributed FS with good performance on small files. We have few tens (up to hundred) of hosts for distributed compilation tasks (that's why small files) and others (not so small files). OSDs should work as clients as well. Now we run on NFSv3 and fight with it (not atomic, not coherent, hard to scale). But NFS performance is not awful really, new FS should work at least not worse than it (I mean aggregated performance). It would be really good if RedHat takes care of it.
