Why Cool threads!

Mark handed over to Fred DeSantis, who presented a new metric for comparing systems, its called SWAP and is calculated by taking a capability outputs and dividing it by the product of space and power. i.e.

P/(S\*W)

where P = Performance, S = space and W = Power (i.e. electricity, and don't forget to add the power to cool). This reminds me of some work I did for one of the bank's two years ago, although I plotted two axis, Performance/Rack Unit and Heat/Rack Unit. Fred then called Mark back to the podium and they ran a data centre simulator, it looks really good and showed that the T1 based systems are cheaper to run, need less cooling, consume less power and need less systems to meet a performance target. The simulation looks really cute, I'm glad to see that the Terraspring user interface came in useful somewhere. (Interestingly, it provoked the thought that in the UK, we rarely model the A/C space or capital costs when exploring consolidation future state scenarios.)

Two users were then asked to give testimonials, the first was Rene Weinholtz, from Strato AG, a web hosting company. You should have seen Jonathan's face when he said that they didn't have an environmental problem. Brits don't expect to meet funny Germans. I'm a bit more broad minded since watching Deutsche Welle on Sky and visiting Berlin over the summer. Rene was actually very funny, but got serious when he described his system consumption in tonnes and stated that they expected US T1 to save them 85-90% of their space and power consumption. Mattias Schorer, from Fiducia AG stated that his company had seen 4-6 performance increase in their banking application and had in fact broken their load generator capacity. They had had to buy additional systems to complete their testing.
