An update to my previous post concerning my Pi-Rack: As mentioned in my recent previous post I have been expanding my Pi-Rack capabilities. The following picture is my current configuration. PI-Rack The Pi-Rack is basically my home server rack using Raspberry PIs as my servers. You can see from the picture that I have four PIs, one 3B and the rest 4Bs. From left to right: Pi #1 is my VPN Pi #2 is my web server which host this site Pi #3 is Pi-hole, a DNS / Ad block Pi #4 is my NAS (Network Attached Storage) or File Server The NAS PI has, next to it, two 1TB USB WD Passports drives in a Raid-1 configuration.
