5 Agenda Efficiency Defined What has changed? State of the data center Trends in data center energy efficiency What is feasible? Q&A 5

6 What Changed? Presentation Public Law just released Since Then? Awareness Efficiency, DCIM rise in priority Benchmarking & Use of Metrics Collaboration Demand strong 50% of DC Managers adding capacity in 2012 Over 70% DC Managers interested in Efficiency/DCIM 6

7 State of the Data Center Energy = 40%+ of cost for Enterprise IT teams Increased Collaboration PUE (Power Usage Effectiveness) Certifications Users Driving Scale The cloud Users demand availability Vertical, not just horizontal, Scale 7

8 Vertical Scale? Xbox Cray Supercomputer 8

9 Data Center Energy Efficiency Trends Expanded envelope Airflow Management Containment In Row Cooling Free Cooling High Voltage Distribution DCIM 9

10 Expanded Envelope Low End Temperature High End Temperature Low End Moisture High End Moisture C (68 F) 25 C (77 F) 40% RH 55% RH C (64.4 F) 27 C (80.6 F) 5.5 C DP (41.9 F DP) 60% RH & 15 C DP (59 F DP) 10

11 ENERGY OPTIMIZATION SPECIALISTS Expanded Envelope 11

12 Expanded Envelope Most DC Today = degF increase = 3% energy savings Temp Sensor locations What are we trying to cool? How to implement 12

13 ENERGY OPTIMIZATION SPECIALISTS Airflow Management Quick Review How Does IT Equipment move air? Problems Air Mixing, Exhaust Air Recirculation 13

14 Airflow Management - Containment Two Forms HACS Hot Aisle Containment System CACS Cold Aisle Containment System Application specific Several Strategies for each Curtains Chimneys Manufactured out of the box Custom 14

15 Hot Aisle Containment System ENERGY OPTIMIZATION SPECIALISTS 15

16 Cold Aisle Containment System ENERGY OPTIMIZATION SPECIALISTS 16

17 What is Best? Application Specific No universal solution CACS in Retrofit Applications Downflow CRAC/CRAH w Open Return HACS in New Construction Slab on grade In row cooling High Density areas 5% - 10% savings, 2 year ROI 17

18 In Row Cooling History Shorten Supply/Return Airflow paths Better Redundancy 18

19 In Row Cooling 19

20 Economization Free Cooling What is it Two Forms Air Side Economizer ( direct ) Water Side Economizer ( indirect ) Can we use it? 20

21 Water Side Economizer Use outside air to cool water supplied to chiller Best Conditions: WB temp 55degF or less for 3,000 hrs/yr Existing chilled water plant New CW builds Chiller Plant Savings 70% when operating in economizer mode 21

22 ENERGY OPTIMIZATION SPECIALISTS Water Side Economizer 22

23 Air Side Economizer Supply Outside Air directly to IT Equipment Location is critical to maximize savings 23

24 How does it work? 24

25 Air Side Economizer Important Considerations Space Flexibility of operating conditions in data center Redundancy Monitoring Cost Best for new construction Savings 30% minimum over traditional data center 25

26 High Voltage Distribution Historical Approach Power Distribution 26

27 High Voltage Distribution Power Supply Configuration auto sensing 100v-240v 27

28 High Voltage Distribution What do we get? Increased Available Power Example 20A Circuit 92% increase in available power at 240V vs traditional Approx 20% less weight/space Reduced wire size Considerations Difficult to retrofit Highly recommended for new construction 28
