A Pi-Powered Plan 9 Cluster
In this post, we take a quick look at the Plan 9 O/S and some of the notable features, before moving on to the construction of a self-contained 4-node Raspberry Pi cluster that will provide a compact platform for experimentation. The idea with the Pi cluster is to have a self-contained system, or rather a neatly packaged distributed system, that can be used for experimenting with Plan 9. If you’d like to build your own 4-node Pi cluster, to run Plan 9 or some other operating system(s), you can find the design files for the case on GitHub.
