2. Agenda Green IT : context & foundations Green IT : Strategy & Prospective CG Datacenter : The world’ s most sustainable data center Datacenter Consolidation

3. Green IT / Green Computing : Few numbers IT energy management is the analysis and management of energy demand within the information technology arena. IT energy demand accounts for approximately 2% of global energy demand, approximately the same level as aviation. IT can account for 25% of a modern office building’s energy cost. The main sources of IT energy demand are PCs and Monitors, accounting for 39% of energy use, followed by data centers and servers, accounting for 23% of energy use. Communication & Information Infrastructure (TIC) eat 13,5 % of the power in France and are responsible of 5% of CO2 footprint in the country. PC consumption of electricity increases by 5% every year. Electrical power accounts for 10 % within CIO budget. Electrical power cost over PC lifecycle is now much higher than PC purchase. PC manufacturing in China rejects 24 times more CO2 than a one year usage in France.. Average Server Utilization rate : < 6 % (even below 3% for 30 % installed into one DC) 5 à 10 % for Wintel server, 20 % for Unix, between 50 à 60 % for large systems => 20% in average for large company (IDC). DC Utilization rate : 56 % of its capability.

4. Green IT / Green Computing : Approaches Different way to optimize energy consumption and ecological footprint Product Longevity PC manufacturing process accounts for 70 % of the natural resources used in the life cycle of a PC the biggest contribution to green computing usually is to prolong the equipment's lifetime manufacturing a new PC makes a far bigger ecological footprintthan manufacturing a new RAM module to upgrade an existing one, a common upgrade that saves the user having to purchase a new computer Software and deployment optimization Algorithmic efficiency : The efficiency of algorithms/program has an impact on the amount of computer resources required (eg. Harward Survey on Google search; GreenIt benchmark)

7. improved utilization of computing resources (CUOD ;

8. Improved the security layers (user isolation, NW segregation…)

10. TCO (asset Mgt / capitalization…)

11. Data security / Data leak protectionPower management Operating system support : Windows 2000 was the first NT based operating system to include power management and the Group Policy. It allows the OS to control the power saving aspects : undervolting, SpeedStep (Intel) solution ; and further (standby / Hybernation…)

12. Green IT / Green Computing : Datacenter Focus is now clearly on facilities and power consumption !

70. Datacenter Consolidation Based on previous elements, it becomes now obvious that DC consolidation will become a strategic initiative for large companies : Four categories of business benefits in data center consolidation: Reduced costs (of staff, building and complexity) Keeping up with business challenges Improving service levels and availability Minimizing the impact of external pressures

71. In a nutshell… Lifecycle Mgt for every piece of the infrastructure to amortize gray energy and decrease building and recycling effects. Leverage software capabilities and features to automatically switch off / standby PC and laptop, CUOD for large batch treatment / BCRS (eg. A PC switched on 24*7 cost 30€ more every year). Virtualization and Cloud computing to optimize utilization rate of the HW and other equipments. Optimize power consumption for cooling and DC facilities. Reuse lost energy (eg. Hot air) for external needs (eg. heating…) Encourage renewal energy for DC provisioning (eg. Google initiatives and research…)
