Tim, Jay --
I looked in to this recently as it was a use-case some of our HPC users wanted support for. I noticed that Ceph has the iSCSI gateway, but my impression was that this wouldn't work without adding some sort of new driver in Cinder. Is that not true? I thought that Cinder only Ceph via RBD. I'd be happy to be proven wrong on this.

Good thought. That would be an interim solution until we are able to
get the process automated.
