[ovirt-users] ovirt and gluster disk config

Hey, been a few years since I looked at ovirt. 3 years probably and at the time I was looking for compute and storage all in one -and was advised not to basically. So Hyperconvergence is now a thing and want to try it out. I was looking at the blog - up and running with ovirt 4.1, but it seems that is mostly for a lab setup. I've got some real hardware I am going to try this out on as a PoC, 5 Dell R720s with 12 TB raw storage in each. Just wondered if there was a guide to the hardware setup of my storage that I am missing? Should I configure the storage as hardware RAID before I start installing the Nodes? I did setup glusterfs cluster 3 years ago as well but memory fails me on how I had the RAID controller setup if at all. Thanks
