Coluccio Respond to of 46821 Hi Elmat, Further to our upstream discussion on the shifts taking place in data center architectures, I posted the following article to the Cook Report Architecture-Econonics Discussion Group earlier today in response to someone's question concerning if economics was still a topic of interest there: Some of us look at the economics closely, some very closely. It's that we don't discuss it very much anymore, and I'm guessing this is due to a prevailing notion held by members similar to that which you just expressed (above). So thanks for breaking the ice ;) Until I read your comment I was on the fence about posting an article on the economies and dis-economies of scale in a continuum of data center sizes and designs; telecoms networks employing GPON technologies; and, (drum roll) in the design of space vehicles, as well. In the telecoms part, I spoke with a colleague about how economies (and dis-economies) were achieved, illustrating how break-even benchmarks are established and exceeded, and how modulating the number of end points downward from the break-even point (as well as a host of environmental variables) can result in insufficient scale of operations, manifesting increasing the dis-economies of scale, proportionately. The conversation was in some ways similar, and in some ways diametrically opposite, two articles I'd came across earlier in the day. The first article was on the scaling (and physical sizing) of server populations within hyper-scale data centers, in contrast with the second article that discussed the number of booster engines now being employed in SpaceX rockets. While the former seems to have reached a tipping point for certain compute situations which have reached massively hyper-scale proportions, argues Amazon's AWS data center architect James Hamilton (see article, immediately below), the latter (rocket designs) are now in the early phases of scaling up the number of parallel engines used, as explained by Elon Musk in today's ars technica article (bottom).Tensor Processing Unit By James Hamilton | Perspectives blog | Amazon AWS perspectives.mvdirona.com Musk explains why SpaceX prefers clusters of small engines By Eric Berger | ars technica arstechnica.com I'd be interested in reading any and all comments, corrections, etc.FAC ------
