7. © 2011 IBM Corporation Green Computing Challenges Demand for computing capability only growing => Peta->Exa, Ubiquitous computing, Clouds Energy cost rivals IT equipment cost Server energy expense grew 31% over last five years Challenge to lower power but maintain reliable operations CMOS scaling limitations Availability vs Efficiency Productivity vs Efficiency Software bloat – modularity for rapid development over efficiency Loss of insight into physical resource usage Barriers to new technology adoption Widespread deployment of and dependence on current technologies Cost of technology development - fewer players with consolidation? Challenge to utilize renewable energy sources to power IT Variability in energy availability and energy storage technology limitations Inefficiencies in and higher cost of renewable energy production
