====Initial Head Node Architecture====

{{ :head_node_setup_v2.png?600 |}}

As of April 28, this is the new network I have configured.

  * The head node is Ubuntu 16.04LTS. Is is the boot server. It facilitates the 10.1.48.x network.
  * The 2 Antonio computers are on the 10.1.48.x. They network boot. They both have 2 internal 5TB hard disks that are not mounted yet.
  * The SNAP and PI should be operational and is plugged into a good new Antonio feed. The SNAP is plugged into the 10GbE network and data should accessible by the 2 Antonio computers.
  * We should be able to stream data directly from the beamformer into the 40GbE ports.

NOTES, THINGS I NEED HELP WITH:

  * I named the computers NGS-Head, NGS-I7, NGS-XP. NGS stands for **N**ew **S**ETI **G**roup. If you want another naming convention, feel free to let me know or change it yourself. 
  * You guys are free to log in and change whatever you want. I need you to email me your public ssh keys.
  * I need help from Jack or Dave to figure out some network boot things. Such as how to tailor the 10GbE ports on the Antonio computer (via network boot), how to assign hostnames, etc.
  * I need to be tutored on setting up the gateways, etc., so these computers have access to the internet. Arg! I have trouble with that.
  * The GPUs are not set up yet, the drivers not installed. That is a network boot thing we'll have to figure out.

I refer to the **"Antonio Computers"**. This is the Xeon Phi and i7 computer pair that Franklin Antonio bought us.
