Lays out the case for how using virtualization can save very significant amounts of energy, especially in large data centers. Breaks down resource requirements in terms of RAM, storage and ultimately cooling for a stand alone server configuration and a comparable virtualization configuration and builds a case for why and how virtualization can significantly reduce energy usage requirements for data centers.
In this post Rien discusses the paradox that pervades so much of the high tech and cleantech world; the world that is supposed ot bring us a green and clean future free from the polluting industries of the “old” industrial paradigm. AND yet, so much of cleantech (and high-tech) depends in often critical ways on rare earths. Rare earth mining and refining is a very dirty business that has lead to some pretty horrible pollution, mainly in the Chinese regions in which it is mostly sourced from. This post focuses on a major new refining operation that Australian mining giant Lynas is trying to open in the country of Malaysia; an operation that is being opposed both by Malaysian activists and by some Australian Green Party activists as well. It forces us all to ponder this paradox and ask ourselves just how green is the green economy?
In this post Julius discusses some of the innovations that are cropping up in forward thinking data center design ranging from the adoption of Yahoo’s chicken coop architecture that is suited for utilizing ambient air cooling; new server designs optimized for hot aisle/cold aisle architecture; and innovative approaches to power supply. While most operators do not have the deep pockets and resources of players like Facebook, Google, Yahoo or Amazon — all mentioned in this post — the kinds of forward thinking innovations being pioneered by these companies are bound to have a wider impact.
