There aren't too many people running RAID under Ceph, as it's a second
layer of redundancy that in normal circumstances is a bit pointless.
But there are scenarios where it might be useful. You might check the
list archives for the anti-cephalopod question thread.

Having heard some suggestions on RAID configuration under Gluster (we have
someone else doing that evaluation, I’m doing the Ceph piece), I’m wondering
what (if any) RAID configurations would be recommended for Ceph. I have
the impression that striping data could counteract/undermine data
replication (with PGs potentially being on multiple disks, rather than
within a single disk-oriented OSD).
