My first run at openstack at home was buying several used Dell servers (2 1950s and 1 2950). This had a couple issues. First was the noise. These servers had a lot of noise with their fans. The second was the energy cost because I had both redundant power supplies running. Given these issues I decided to write an article on how to build our a compute node yourself. If you’re building a lab then you really want your paower to be on the compute node, hence that is what we will be building. You can use a laptop for the openstack controller as this doesn’t require that much power.
