Clustering Novena Server clustering is a topic I’ve been cirous about for a rather long time, from back in the Slashdot days where one would constantly “imagine a beowulf cluster of” any given low-powered device. With modern clustering software, such thoughts become practical reality. And with some cardboard, everything goes together nicely. To start with, I cut up some shipping boxes, laid the mainboard on top, and made some marks with a pen.
