Unfortunately there is not a lot of info out there about ideal hardware configs for hyperconverged oVirt (at least not that I have found to date, and believe me I've looked). If you have enough drives and especially if they are spinning disks as far as I know your best option would likely be to do a RAID-10 config to make up a single glusterfs brick on each physical server. Raid-10 will add some performance benefits and also give you some options to replace failed disks without bringing the brick offline. The downfall is that you waste a ton of usable space with Raid + gluster because each offer redundancy.
I'm about to build a 3 node hyperconverted oVirt setup on Dell R720s myself, but I'm planning on using two 2Tb SSDs in JBOD configuration per host w/ a gluster replica 3. I've gone back and forth on using JBOD or Raid config with SSDs and never did get a clear answer (online or asking on this mailing list). SSDs are too expensive right now to lose half usable space to raid then another half or more to gluster replication.
