Are these spinning or SSD/NVME ? For me a Raid60 is an overkill, as you need 'replica 2 arbiter 1' or pure 'replica 3' when you care about your data. I'd recommend you to add a separate node (either physical or Virtual) as an Arbiter. Most probably a raid5/50 will be enough, but you can adapt in the POC stage. If you plan to use NFS - consider NFS Ganesha in a HA cluster, as the built-in NFS is deprecated (and in some distributions you need to rebuild from source).Also consider it as a 'gateway' which means that the NFS Ganesha should have more NICs. If NFS Ganesha is used - you won't need the second group of NICs on the Gluster nodes. Ganesha directly speeks with all nodes in the storage pool. So, you can try with 3 Gluster nodes and a node for NFS Ganesha and later scale-out.
