My rigs are a cluster of 4 nodes each and one embedded *BSD licensed controller of my own design. Each one has 8 8 core cpus, 512GB of RAM and 12 GPU cards with logging and storage done in an encrypted VIA Mini ITX controlling a storage array (so an error won't crash the system by filling up system disks). The other rig is exactly the same, located in a different location with the same colo company and has hot failover capability with the other machine using something Linux HA heartbeat.
