Is anyone using ScaleIO (from Dell EMC) as a Cinder storage provider? What has been your experience with it, and at what scale? Our enterprise storage team is moving to ScaleIO and wants our OpenStack deployments to use it, so I'm looking for real life experiences to calibrate vendor stories of wonderfulness. 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.
