[ovirt-users] low power, low cost glusterfs storage

Hello everybody! Does anyone here have experience with a cheap, energy-saving glusterfs storage solution? I'm thinking of something that has more power than a rasbian Pi, 3 x 2 TB (SSD) storage, but doesn't cost much more and doesn't consume much more power. Would that be possible? I know the "Red Hat Gluster Storage" requirements, but are they generally so high? Only a few VM images would have to be on it... Greetings Jonathan
