Really too much like an interview question to be simply answered by anyone here but since Ray has already handled an identical question in the past, I'll link to it:

Go find the Grid Enablement Toolkit Redbook. It will be helpfull.

In a nutshell:

Head Node = Job coordinator.
Compute Node = worker bee(s)

Don't crunch numbers on your head node.
Don't move data from your head node.

You only have one head node, but you can have a ton of compute nodes. Move work to compute nodes and free up more room on the IP Stack of the head node.
