Their probably do clustering on the OS level, with something like LVS, heartbeat, etc

cPanel is not an OS, nor does it do stuff like clustering / networking / etc. It can, however control stuff like Apache, Exim, MySQL, etc etc. If the servers are clustered on the OS level, it doesn't matter what control panel you use, or don't use, it's still a cluster
