By the look of the basic HPC cluster set up, is the head node a server, like a rack of server blade?

Yep. Basically the head node is just another server, only one that doesn't do any computationally intense programming, doesn't need high-speed interconnects to the other compute nodes or storage nodes. You could use either another blade, or a 1U rack server, or probably even a powerful workstation, but only if you had server-grade disks and other components in it. Using a server is probably the recommended method. | |||
