One concern I do have is that it uses a proprietary protocol that in turn requires a proprietary “data client”. For VM hosting this data client can be installed in the compute node host OS, but seems like we wouldn’t be able to boot a bare-metal instance from a ScaleIO-backed Cinder volume.
Not supporting iSCSI would indeed be an issue for bare-metal instances. The same basic issue exists for Ceph backed storage, although I've been encouraging the cinder team to provide a capability of returning an iscsi volume mapping for Ceph. If there is a similar possibility, please let me know as it might change the overall discussion regarding providing storage for bare metal instances. -Julia
