Two Pi R
================================================================================
Although many people are excited about the hardware-hacking possibilities with the Raspberry Pi, one of the things that interests me most is the fact that it is essentially a small low-power Linux server I can use to replace other Linux servers I already have around the house. In previous columns, I've talked about using the Raspberry Pi to replace the server that controls my beer fridge and colocating a Raspberry Pi in Austria. After I colocated a Raspberry Pi in Austria, I started thinking about the advantages and disadvantages of using something with so many single points of failure as a server I relied on, so I started thinking about ways to handle that single point of failure. When you see "Two Pi R", you probably think the R stands for the radius for a circle. To me, it stands for redundancy. I came to the conclusion that although one Pi isn't redundant, two Pi are.
