What is the big deal with Virtualization?
gaius: I am a cynic (who has completed a few P2V projects) and I would say that many if not most people don't understand that virtualization is just one possible technique for consolidation. Consolidation matters because what is constraining datacentres right now is power, cooling and floor loading. Computational power per kilowatt and per square foot are the new metrics that matter (you assume that everything is 42U tall and work in 2 dimensions). Serious datacentre operators have long been happy to pay a premium for density.
