Bill, that is for sharing your findings I've also been curious as well and haven't had much luck finding reference hardware or expected performance from HCI builds. I just put together three top end r720s with 256gb ram and two 2tb SSDs in jbod per host with 10gbe backend for gluster. I just finished racking the servers and haven't had a chance to start the Ovirt install yet but hope to get to it within the next couple of weeks.. I've been a bit worried about the performance of gluster, I'm hoping I won't be disappointed.
