6 Customer Voices Top 3 Concerns in DC Selection NTT Customer Survey 2012 to 2014 Cost of Ownership Reliability SLA Cost Value

7 What is the Averaged Power Density Trend? Virtualization Drives Power Density IT Power & Efficiency kw/rack Current Power Density Average Power Density Max Power Density Virtualized Infrastructure Non-virtualized Infrastructure Actual utilization ranges between 10% to 60% Average Power Density Continues to Increase Lower bound of average power density will continue to grow due to adoption of virtualization for better IT efficiency & utilization Upper bound of average power density maintains 10kW/rack due to facility limitation

8 How High Could the Power Density Go? Computing Output SPECpower_ssj2008 Maximum Power Density Peaks At 20kW/rack Energy efficiency of IT equipment continues to improve across any utilization level IT equipment advancement peaks the maximum power density at 20kW/rack Server Power Consumption Watt per U Application of ARM-based CPU in commercial server in 2013 Year

10 Data Center Environmental Requirements Recommended environmental envelope for IT equipment by ASHRAE (American Society of Heating, Refrigeration, Air Conditioning and Engineers, Inc.) Recommended Envelope Allowable Envelope (A1) Allowable Envelope (A2) Allowable Envelope (A3) Allowable Envelope (A4) Temperature 18 to 27 C 15 to 32 C 11 to 35 C 5 to 40 C 5 to 45 C Max. temp for storage/ hour Humidity Application Referred by most data centers to define operational & SLA range 5 or 20 C 5 or 20 C 5 or 20 C 5 or 20 C 5 or 20 C 5.5 C DP & 60%RH; 15 C DP Most reliable & reasonable energy efficient range 20 to 80%RH 20 to 80%RH -12 C DP; 8 to 82%RH Compressor-based cooling Functional for limited duration Free cooling -12 C DP; 8 to 90%RH

14 Continuous Cooling for HD Data Centers Why Continuous Cooling? CRAH 2-3min Chilled Water Pump 0.5min Chiller 7-20min Condensing Water Pump 0.5min Full capacity Restart time after power interruption (min.) Cooling Tower 0.5 min What is Continuous Cooling? Continuous Cooling is defined as the ability to provide stable cooling to the IT and UPS environment without any interruption. Continuous Cooling is recommended at densities beyond 4kW/rack, regardless of Tier.

15 How to Stay in the Envelopes? 1. Cool the data center to 18 C to gain air-side thermal buffer (lower bound of recommended envelope) Zero capital investment High energy cost Short ride-through time Limitation on power density Limitation on application of containment solution for energy saving Need to consider rate of change of temperature

16 How to Stay in the Envelopes? 2. Keep the cooling system running continuously Uninterrupted Power for All Cooling Components UPS UPS UPS Uninterrupted Power + Water Side Thermal Storage UPS UPS Thermal Energy Storage Capital investment needed Energy cost saving by raising the data center operating temperature up to 27⁰C (upper bound of recommended envelope) Ride-through time can be chosen No limitation on power density No limitation on application of containment solution for energy saving Better SLA on thermal stability

17 What is the Effective Way to Cool HD Data Centers? Front-flow Cooling with Hot Aisle Containment Higher cooling capacity Better energy efficient More vertical space for IT equipment Cooling Corridor Return Air Plenum Cooling Corridor CRAH unit Cooling Coil ICT Hall Low Speed Airflow Rack Rack Hot Aisle Contained Rack Rack Rack Rack Low Speed Airflow CRAH unit Cooling Coil Front-flow cooling with hot aisle containment Cooling Corridor Return Air Plenum Cooling Corridor CRAH unit Cooling Coil ICT Hall Leakage Rack Rack Cold Aisle Contained Rack Rack Rack Rack Leakage CRAH unit Cooling Coil Down-flow cooling with cold aisle containment High Speed Airflow High Speed Airflow

28 High-Density Colocation 1. Desire to maximizing IT efficiency & utilization continues to drive average rack power density in data centers. Data center for high-density shall be properly designed to maintain IT reliability. 2. There is high potential to reduce the data center TCO at high density, by lowering both the fixed asset cost and variable energy cost.

29 Enhanced Visibility 1. Visibility to data center performance can be enhanced through integrated automation of disparate equipment and systems of data center facility infrastructure. 2. Enhanced visibility allows access to real-time and historical data center performance, that helps business to reduce risk by making informative decision, and enables effective data center planning in a long run.
