5. Building energy codes are causing companies to re-think DC thermal management:

6. (Standard 90.1) requires efficient cooling ; systems must use airside economizers; includes all commercial buildings DCs

7. Save Energy Now aims to reduce energy use in U.S. data centers 10% by 2011

8. Compliance with various standards such as ASHRAE TC9.9 and LEED75% of medium-to-large enterprises are implementing “high density” computing platforms. - this number will approach 100% by 2010 . – IDC

10. Pressure to optimize cooling schemas, equipment layout, and HVAC deployment

11. Effective ventilation and cooling is critical to ensure uninterrupted operation

12. The environmental conditions are controlled by numerous factors, these include:

13. Layout and open area of perforated tiles

14. Location and characteristics of the cooling units

15. Layout and heat loads of server racks

16. Presence of obstructions

18. Modify layout and/or open area of the perforated tiles

19. Change locations of cooling units/add new cooling units

20. Include Return ceiling plenum - use of Chimney racks

21. Incorporate hot aisle/cold aisle containment systems

22. Managers of these facilities are turning to airflow modeling for cooling optimization

24. Evaluate several options to determine optimum solution

25. Reduce capital expense and running cost

26. Save time on commissioning

29. Robust models and algorithms

30. Unparalleled ease of use

31. Unmatched solution speed

32. Thoroughly validated

34. Animations of air movement and temperature traverses

35. Temperature fog to visualize hot spots

36. Flashing lights for overheated racks

37. Customized HTML report

39. Identify and eliminate hot spots

40. Understand the operation of cooling devices

41. Evaluate new cooling solutions

42. Get guidance for expansion

43. Study “what if” scenarios

49. Server utilization views may be used to show trending of server utilization, power, and cost.16 Copyright © 2011 Viridity Software, Inc. All Rights Reserved Server Utilization view

51. View may be filtered by asset owner, contact, or at application level

52. Reports yearly power cost based on avg CPU utilization

53. Assets can be considered for virtualization, consolidation, or elimination 17 Copyright © 2011 Viridity Software, Inc. All Rights Reserved

55. 2-D visualization of the datacenter highlights racks with underutilized assets.

56. Select a rack in the 2-D view to see the details in the right-side inspector window. Underutilized servers are highlighted in “blue”.18 Copyright © 2011 Viridity Software, Inc. All Rights Reserved

58. EnergyCenter leverages its unique power profile database to graph the worst case power utilization value (in green).

59. Remaining power capacity is the difference between the blue and green lines

60. Change the view to “Average Power” to get a per-asset view of the power utilization in the rack.

61. Move the cursor over specific slices to view average utilization and yearly cost info. 19 Copyright © 2011 Viridity Software, Inc. All Rights Reserved

64. In the current layout, many servers inlet temperatures were measured above 90 degrees (with some over 100 degrees). Viridity’s on-site visual inspection of the datacenter confirmed these temperature calculations.ASHREA recommends for inlet temperatures for servers in category 1 datacenters remain below 98 degrees. 21 Copyright © 2011 Viridity Software, Inc.
