Addressing Reliability vs. Efficiency Paradigm The key challenge for Data Center managers How to achieve higher efficiencies without compromising reliability Historical trade-off Double-conversion: maximum level of protection at a cost Other legacy modes: compromise on reliability The solution = two new game-changing UPS technologies Variable Module Management System (VMMS) Maximized efficiency in double conversion mode Both in single- and multi-UPS systems applications Energy Saver System (ESS) The ultimate savings: 99% efficiency Automatic fast transfer to double conversion mode when needed (in less than 2 ms) Higher System Efficiency No Compromise On Reliability

10. 10 © 2014 Eaton. All rights reserved. Variable Module Management System In double conversion mode, the efficiency of any UPS varies depending on the % of load Highest efficiency when close to full capacity UPS systems rarely loaded at full capacity This is the fact in redundant systems as used in most data centers  How to maximize efficiency potential of UPS systems with lighter loads FACTSFACTS CHALLENGECHALLENGE

11. 11 © 2014 Eaton. All rights reserved. Variable Module Management System How to maximize efficiency with lighter loads in double conversion mode Especially in multi-UPS and redundant system configurations Solution #1 (basic) Concentrate load on certain UPS’s to maximize UPS load level and overall system efficiency Some energy savings Limited to multiple-UPS systems (with several UPS in parallel) Still not optimal Solution #2 (more advanced & efficient) Automatically optimize efficiency at UPM level  VMMS Concentrate the load on certain UPM’s to maximize overall system efficiency Only possible on modular UPS’s Not limited to multiple-UPS systems Achieve even higher optimization thanks to UPM’s modularity

Variable Module Management System VMMS Benefits Maximized efficiency in double conversion mode  higher efficiency Typical applications where VMMS is particularly efficient Redundant N+1 and 2N systems UPS’s Lightly loaded: typically operate at loads < 45% load level where efficiency is not optimal Data Centers, especially when UPS system feeds dual corded servers Any applications when load is not constant

16. 16 © 2014 Eaton. All rights reserved. Energy Saver System Energy Saver System Principle Until recently, upper limit for UPS energy efficiency in double-conversion ~96% In developed countries, utility power is within industry specifications most of the time Complete power conditioning is needed only rarely Yet traditional double conversion UPS’s continuously process utility power, converting it from AC to DC and back to AC again Dissipating heat and wasting power at every stage. Energy Saver System technology delivers 99% efficiency by intelligently adapting to utility power conditions and operating in energy-saving mode most of the time Offering double-conversion protection when your load needs it As quickly as it needs it

21. 21 © 2014 Eaton. All rights reserved. Energy Saver System Some form of multi-mode capability has been available on UPS’s for years However, conventional multi-mode UPS’s have their limitations Trade-off between reliability and efficiency What differentiates ESS from traditional “ECO-Mode” Conventional ECO-mode is accomplished in one of two ways Power the load with Bypass Utility and wait for the UPS to start, sync, and transfer to double conversion mode when disturbances occur  Long transition times to inverter Operate in line interactive mode with the inverter running for faster transitions to double conversion mode  Increased power losses resulting in reduced efficiency ESS solves both issues It provides best possible efficiency, and instantaneous transfer to double conversion when needed

The bottom line ESS drives the UPS losses close to zero The energy savings from ESS typically recovers 100% of the UPS cost over a 3 - 5 year period At 250kW of critical load, the savings is equivalent to 3 600 € per year per point of efficiency gain Calculation is based on 60% DCiE and CO2 emissions at 400g/kWh medium European level Energy Saver System

FP7 ICT-2013.6.2 Data Centre Project GreenDataNet Call for projects “Development of system level technologies and associated services that improve the energy and environmental performance of urban data centers” »SW/HW system level technologies/services for energy monitoring and optimization »Integration of networks of renewable energy sources »Efficient heat reuse at urban neighborhood level »Integration of data centers with smart grid schemes »Standardization of energy measurement/environmental footprint »Validation in real settings/use cases

25. Trend #1 Demand for IT services is increasing faster than the capacity of technology to absorb it at constant power usage

26. 10% of all the world’s electricity is used by IT Source: Digital Power Group report "The Cloud Begins With Coal – Big Data, Big Networks, Big Infrastructure, and Big Power" IT now uses more energy than air transport

27. Brontobytes of data and mobile demand are currently running faster than technology Smart mobile devicesThe Internet of Things Source: IDC Digital Universe 2013 Source: nojitter.com A data explosion Source: Cisco, VNI Mobile Forecast, 2013

28. Trend #2 Modern data centers are increasingly energy proportional

29. Modern IT and modern facility designs are more proportional IT Large hardware clusters under Hypervisors and Cloud orchestrators bring: Better utilization rate Less resources waste Elasticity and immediate response to demand IT Hardware active power management technology is increasingly available Facility Critical power chains are better at scaling up and down automatically: Modular designs, idle capacity switch-off Less redundancy for the same resilience level Use of “free cooling” and advanced cooling techniques

30. Data centers used to provide a constant base load for power stations – now this load is increasingly volatile as their energy consumption becomes more proportional to the IT services actually consumed Consequences for utilities

31. Trend #3 The sustained increase in the proportion of renewables and grid priority rules are making power generation more volatile

32. Renewables intermittency is changing the face of the electrical power market Renewables production gyrates wildly…while traditional generation suffers

33. The opportunity Turning a complex challenge into a significant opportunity for optimization

35. Development of energy proportional data centers through optimization of IT loads and cooling Development of greener data centers through use of local renewable energies Use of new battery technologies from the automotive market to store energy and help mitigate power generation and usage imbalance How to mitigate the combined impact of three positive developments?

36. Today the data center is a black box?

37. Project Proposal: Monitoring and optimization from rack to grid

38. The solution will combine hardware and software to optimize energy usage

39.
