[ovirt-users] Storage Hardware for Hyperconverged oVirt: Gluster best practice

oVirt + Gluster (hyperconverged) RAID question: I have 3 nodes of SuperMicro hardware, each node has 1x SATADOM (boot drive for o/s install) and 6x 1TB SSD (to be used for Gluster). For the SSDs, is hardware or software RAID preferred or do I use an HBA? The RedHat docs seem to suggest hardware RAID, others on the forum say HBA or software RAID. What are other folks using?
