Kinetic is interesting, but I think it's going to find more uptake among big Open Compute users like Facebook than in general distributed storage systems. In particular, these drives don't appear to have the CPU power required to run OSDs, and their native interfaces don't have the strength to be useful underneath. -Greg -- Software Engineer #42 @ http://inktank.com | http://ceph.com
