3 High enterprise relevancy for addressing space, power, and cooling, as well as costs and skills for environments Large and enterprise-scale data center growth of 11% and 7% respectively, Data Center Trends Critical facilities design Design alterations based on density improvements In 2016, the same floor space will be able to house 22% more equipment than in 2011 More efficient data center design through modularity adoption Critical facilities strategy Optimized Critical facilities implementation According to the 2012 Uptime Institute survey, 80% of respondents have built a new data center or upgraded an existing facility within the past five years, and 30% of respondents ran out of data center capacity at one of their sites in An alarming inaccuracy for data center operators managing the thermal conditions at the room level, not the rack inlet level Available Between more than 11,000 new data centers will be constructed globally When building a new data center, around half of the respondents are interested in pursuing some kind of green certification, with the leading option being the U.S. Green Building Council s LEED program Critical facilities energy Critical facilities assurance A poorly designed data center may reduce IT and business agility Periodic refurbishment costs to upgrade and replace aging equipment, such as chillers and battery systems, driving TCO decisions

4 Forward-thinking companies have realized that to run data centers efficiently, and to extend their lives indefinitely, it is not logical to treat data center facilities and IT assets separately, because without one the other can t operate.

7 Facilities to IT: Why don t you just do this?

8 How inefficiency can cost business Business impact related to cooling issues Server or system downtime Increased operational costs Data center outage Inability to add capacity Fail to support business growth Loss of revenue Lowered customer satisfaction

23 Energy Audit & Optimization Report Optimizing Air Management Recirculation: results in hot spots and wastes fan energy Consider return air plenum and ductwork for the CRAC units Remove obstructions under the floor that restrict cold air to supply the server inlets Ensure as best as possible the adequate supply of cold air to the server inlets Ensure air velocities and flows from floor grilles are sufficient to reach the top of cabinet servers Fit blanking plates in cabinets where servers are not installed Close gaps between cabinets (where warm air can make its way to the server inlet) Avoid installing highly loaded servers at the end of cabinet row or at the top where recirculation is easier Consider means to physically isolate the supply (cold) and return (hot) air streams Return air Recirculated air (if servers need more air than supplied) Server CRAC Supply air

24 Energy Audit & Optimization Report Optimizing Air Management Bypass: Starves servers from air and wastes fan energy Locate floor air grills so that they supply the inlet of servers, i.e. remove floor air grills from hot aisles and other useless areas Return air Ensure air velocities from floor grilles are not too high and overshoot the cabinet height Seal air gaps in the raised floor CRAC units turned off are a source of air bypass (consider air isolation with dampers) Server Bypass Floor tiles and racks badly located/o riented CRAC High exit velocity

25 Energy Audit & Optimization Report Optimizing Air Management Negative flow: Venturi flow Return air Negative flow if high underfloor air velocity Server CRAC

26 Energy Audit & Optimization Report Air Management Metrics-Practical Applications OPPORTUNITY BP Legacy D C, particularly if not well managed, tend to have high levels of both bypass and recirculation flow rates. Cold aisle hot aisle arrangements can address the main problems of recirculation. However, particularly at low loads, there will be high levels of bypass air, unless the CRAC units have some type of variable air-flow control.

46 Integrated Systems Tests (IST) Failure conditions are simulated to ensure systems react in a manner to which they are designed Used to verify the correct integrated operation of the Data Center in various cause and effect modes of failure

47 Tests conducted during IST Electrical Simulate failure of Main Utility Power and demostrate operation of generator Simulate failure of generator power and demonstrate battery operation of UPS system Simulate failure of UPS System and demonstrate operation of STS System

48 Tests conducted during IST Mechanical Simulate failure of Chiller / Chillers and demonstrate capability of chiller control system Simulate failure of CRAC units and demonstrate capability of CRAC control system Carry out simulation of fire alarms and effect on data center

49 The Process Adjust to Suit Observe use Tune to suit Educate to avoid override

52 Energy Efficiency of Data Centers Due to technological advances, demand for data center space throughout the developed world will remain high. Amount of electricity consumed will be exceptionally high due to the high power demands of data centers It is important to monitor and improve the energy efficiencies of the data centers

53 Recent Government Developments Early appointment of Commissioning Agent to discuss and agree strategies to optimize energy efficiencies within data center Proper sealing of the data center environment Optimizing air flow Increasing cooling system efficiencies System of monitoring and tracking of energy efficiency parameters

54 Improving Energy Efficiency through Commissioning Management Effective commissioning has been shown to improve the operating efficiency and environmental performance of a building over its life cycle. Commissioning is growing in importance due to the growing complexity of buildings Continuous commissioning has been proven to save energy and costs throughout the life of the building
