It's a storage and Kerberos server. It also hosts cslabs.clarkson.edu and is our main "email" server.
Bacon is used for homedirs and Kerberos. It has all of the PXE images on it, provides the COSI website, and also has been used as a general purpose box, IRC bouncer, and jump host.
Originally named Metapod (aka Meatpod), it was the only server not re-installed in Summer 2015 as part of the infrastructure overhauls, due to the system complexity and using BSD as an OS. In September 2016, it was reinstalled with a debian based distro by Bobby and others, making the system more accessible to use.
