Future expansion and a scalable setup

The examples in this book are designed to be scalable. That is if you wish to add more Raspberry Pi's to your network, this should be very easy.

If you plan on running more than two devices you should therefore consider hardware that scales well. Switches for example come with as many as 48 ports.

One area you may find problematic is in providing power to multiple Raspberry Pi computers. Having a huge number of power units of USB hubs can be extremely cluttered. In Chapter 7, Going Further, we suggest several methods for providing power to multiple units.

With the preceding thoughts in mind, let's now complete the initial set up of our hardware.
