Can someone look over this to make sure that I am not on the crazy train. I am looking to spec a cluster for work based on ovirt and gluster. The plan is to use the Gluster auto tiering, the SSD level would be a pair of systems with replicated gluster brick. The HDD level would be 4 systems what would be distributed replicated. For the network each system has a dual port 25gb port and be connected to the 100gb switch with a 4to1 breakout cable.
