The document discusses strategies for making data centers more energy efficient without compromising performance or reliability. It outlines 10 best practices including using more efficient processors and power supplies, server virtualization, improved cooling practices, and monitoring systems. Implementing these holistic strategies from the IT equipment level upwards can significantly reduce energy usage through cascading effects while freeing up capacity.

6. “ Energy Logic” : Energy Efficient Data Centers : A Holistic Way To Reduce Data Center Energy Usage Without Compromising On Reliability.

7. Fact: No Universal Metric For Facility/Data Center Output In the absence of this metric, discussing data center efficiency is not meaningful. We can only talk about reducing data center energy consumption.

8. IT Perspective on Energy Efficiency Top priority is delivering on service level agreements Performance - provide adequate compute capacity Reliability - redundancy at all steps Ability to support Security Does IT care about energy efficiency? Yes, but not if it impacts performance & reliability What if it frees up power and cooling capacity? Yes! If it does not impact performance and reliability

9. What FM/Data Centers Managers Are Looking For Objective ‘vendor – neutral’ analysis Holistic view of the data center Quantification of savings from different strategies Prioritization of actions Actionable advice Tailored to different types of data centers 24x7 vs. 8x5; compute-intensive vs transaction-intensive Payback / ROI analysis to help sell to management

11. Energy Logic: What is it?

12. Energy Logic: The Three Key Messages The most effective strategy to save energy: Start with reducing losses / consumption at the IT equipment level and work your way back through the supporting equipment Every watt saved at the equipment level has a cascading effect upstream As you reduce energy consumption, make sure you do not compromise on availability and flexibility Efficiency Without Compromise ™ High-density architecture helps reduce energy consumption

14. Energy Logic : Cascade Effect

15. Strategy 1: Low-Power Processor Chip makers and independent analysts claim no or negligible impact on compute performance 1

16. Strategy 2: High-Efficiency Power Supplies Right-size your power supply Typically server power supplies are oversized to accommodate maximum server efficiency Even though most servers are shipped at much lower configurations Higher losses associated with oversized power supplies LBNL reported power supply efficiency 72% - 75% at 30% load New power supplies have substantially higher efficiencies 89% - 91% at 30% load 2

17. Which power supply will you choose? Power supply A: 91% efficient at nameplate rating, or power supply B: 93% efficient at nameplate rating? Power supplies are never at nameplate rating Dual power supplies are never loaded at >50% under normal conditions Spec the power supply which is more efficient at 10% - 35% load Strategy 2: High-Efficiency Power Supplies 2

18. Strategy 3: Server Power Management Server processors have power management features built in Can reduce power draw when processor is idle Typical power management features are turned off Turning on power management feature reduces processor idle power to ~45% of peak or less Test your OS / applications for latency Servers consume 75%-80% of peak load power even when the processor is idle 3

19. Strategy 4: Blade Servers Blade servers consume about 10% less power compared to equivalent rackmount servers Common components in chassis – fans, communication cards, etc. Blades enable high-density architecture! Comparison of hardware for rackmount servers & blade servers 4

20. Strategy 5: Server Virtualization Virtualization increases server utilization by decoupling hardware and software Multiple ‘logical servers’ on a physical server Energy savings with fewer number of servers Consolidation ratio of 8:1 are typical Before Virtualization Typical Virtualization Architecture 5

21. Strategy 6: Power Distribution Architecture Servers are capable of taking 240V input Power supplies are 0.6% more efficient at 240V than at 208V Change Power distribution to 415V 3-phase with is 240V line neutral Energy efficiency gain Elimination of PDU transformer losses Improved server power supply efficiency at higher voltage Traditional 208V Distribution Power Supply 6

22. Strategy 7: Implement Cooling Best Practices 7 Place Cooling Units at the end of the hot aisle Optimize Room Reduce Under Floor Obstructions Place High KW in the center of the Row

23. Strategy 7: Implement Cooling Best Practices In Racks Between Racks Use Blanking Panels 7

24. Reduce energy waste Improve vapor barrier – unnecessary humidification / dehumidification Reduce solar heat gain; air leakages in the room, under-floor and ceiling Use optimal set points Proper cold aisle temperature – adjust room set point (20 ° to 21°C) Raise the chilled water temperature above 7°C ASHRAE guideline books available Thermal assessments can help jump start the process Strategy 7: Implement Cooling Best Practices 7

25. Strategy 8: Variable-Capacity Cooling IT loads have a large variation in cooling and airflow requirements Virtualization, power management, new equipment Need to match cooling capacity with the IT load Eliminates over cooling & improves cooling efficiency with reduced cycling 8 Energy cost, 10hp fan motor with variable frequency drive (VFD) Floor mount cooling unit Compressor EER Chilled Water Units Valve (CW) / airflow Reduce airflow Reducing fan speed by 20% reduces power consumption by 50% Variable airflow control with HP DSC DX Units Compressor uploading / airflow Variable compressors Multi-step / Digital Higher EER point

26. Strategy 9: High-Density Supplemental Cooling Higher efficiency gains from “cooling closer to the source” Fan power reduces by up to 65% Higher performance cooling coils Higher entering air temperature 100% sensible cooling Zero footprint cooling solution Cooling capacity available over 30kW/rack 9 Power required to cool 1kW of sensible load

27. Strategy 10: Monitoring and Optimization Use monitoring and optimization tools to improve efficiency Cooling – share data to team multiple units Manage compressor load, humidification, dehumidification and cycling Power – UPS and PDU optimization, management and control 10 Teamwork: None Teamwork: In operation

28. Other Opportunities Identify and disconnect ‘ghost servers’ Servers not performing useful tasks but still consuming power Storage Consolidate data storage from direct attached storage to network attached storage Faster disks consume more power Reorganize data so less frequently used data is on slower drives Use economizers where appropriate Economizers allow outside air to be used to support data center cooling during colder months Monitor and reduce ‘parasitic’ losses Parasitic losses of 30kW to 50kW by generators for 1MW load Exterior lighting, security and fire suppression systems Perimeter access control, employee services

29. Energy Logic: Energy Saving Opportunity Savings potential from each strategy applied individually * For every action, downstream cascading benefits are included. Savings are not cumulative!

30. Unoptimized Data Center Layout

31. Optimized Data Center Layout 65% space freed up from optimization from 463 sq. m. to 164 sq. m.

32. Energy Logic: Energy-Saving Strategies Payback Period

33. Existing facilities Set in place equipment purchase policies (involve procurement dept) When replacing or buying new servers and IT equipment, specify Lowest power processors Most efficient power supplies, at part loads (20% - 35% load) Enable server power management features Savings will not accrue immediately, but over time Start IT projects Move towards blade servers wherever possible (enable high density) Evaluate and implement server virtualization Implement best practice Alternate power distribution architecture Cooling best practices Infrastructure upgrade Variable-capacity cooling High-density supplemental cooling Monitoring and optimization Greenfields sites Design with all strategies implemented on day one or as early as possible!

34. Energy Logic: Three Key Messages The most effective strategy to save energy: Start with reducing losses / consumption at the IT equipment level and work your way back through the supporting equipment Every watt saved at the equipment level has a cascading effect upstream As you reduce energy consumption, make sure you do not compromise on availability and flexibility Efficiency Without Compromise ™ High-density architecture helps reduce energy consumption Even if efficiency is not your key concern, implementing these strategies will free up capacity of your key constraints – power, cooling & space Four
