5 Energy Efficiency in Server Rooms US government reference: 5

6 Energy Efficiency in Server Rooms 7 Energy-efficiency awareness training for IT staff Have your IT and facilities staff attend server room energyefficiency awareness classes offered by utility companies, ASHRAE, and other efficiency advocates, to take full advantage of best practices in that area. 6

7 Measuring Energy Efficiency in Server Rooms Total energy consumption does not take into account variations in size and usage. Preferred method calculates overhead, using Power Usage Effectiveness (PUE) PUE = total energy / computational energy Do you know your PUE and how to manage it? 10 7

8 PUE Scale Google Datacenter Sample 8

9 HVAC Maintenance Increase cooling efficiency up to 25% 9

10 Scheduled HVAC Maintenance In-house HVAC maintenance through IPF Contact IPF (517)

11 Operation of Cooling Equipment Importance of Rack/Device Intake Temperature Room temperature is rarely a valid indication of the temperature at the rack intake Decision on acceptable temperature at the intake of the rack has a significant impact on cooling 11

12 Energy Efficiency in Server Rooms US government reference: 2 Increase temperature set points to the high end of ASHRAE s recommended limit ASHRAE temperature guidelines allow much broader operating ranges than those commonly used, allowing the air temperature at the IT equipment inlet to be raised up to 80ºF or higher which considerably reduces cooling energy usage. 12

13 Impact of server room temperature on PUE 1.7 IPF Server Room % /20 to 8/23 4/20 to 8/23 Server PUE Server PUE at 65 DegF Server PUE at 80 DegF Average PUE at 65 DegF Average PUE at 80 DegF 13

20 Server Room/Data Center Cooling Design Sizing of Cooling Equipment Total Cooling Room Design 20

21 Sizing of Cooling Equipment 14 Importance of right-sizing cooling equipment Cooling undersized = IT Equip./Room too warm Cooling oversized = Erratic temperatures & humidity Oversized cooling equipment leads to short-cycling of cooling equipment and that also leads to failure of equipment Right-sized equipment uses the least amount of energy 21

22 Sizing of Cooling Equipment Understanding actual heat output of IT equipment is critical Growth needs to be considered Selecting cooling size with growth in mind is a delicate balance Space for future, multiple cooling units and equipment turndown are all tools to help deal with growth Variable frequency drives provide flexibility 11 22

23 Total Cooling Room Design Location and Distribution of Cooling Delivering cooling near intake of IT Equipment Hot Aisle, Cold Aisle Hot (or cold) Aisle Containment Underfloor Supply Air Rear Door Heat Exchanger 12 23

24 Hot Aisle Containment 4 24

25 Total Cooling Room Design A properly designed server room is considerably more efficient than converting a standard room into a Server Room Realistic Heat Load of Space Sizing cooling equipment for this can have a valuable impact on performance of both IT and Cooling Equipment Energy Impact Right-Sized Cooling Economizing (Free Cooling) 25
