This page will be a marker for some of the steps required to get certain projects going. Even though many of these will be assigned to specific virtual machines, wanted to have a page linked to all of them in one spot.

The components of our network setup include: HP Procurve 1800-24G – this connects all of the machines together, both on the storage and management
This page will include a rundown of the hardware that I will be using for my sandbox. Bear in mind that you do not need the most recent hardware and you don’t need huge amounts of ram and resources. The key for what we are trying to learn here is how everything works together and
