7 New Development In DC Containment Data Center Industry Challenges: Globally, Data Center energy costs continue to rise at an exponential rate. On average, the cost of energy accounts for 25% of the total operating costs inside the Data Center. In some areas of the United States, kWh costs have risen over 30% between 2012 and With a rate of change that high within 3 years, energy efficiency will continue to be a high priority in the Commercial & Industrial space. As clients continue to virtualize on new servers, move to co-lo facilities & even expand within their existing Data Centers, airflow management will continue to be an area of concern in such dynamic environments.

12 New Development In DC Containment Industry Challenges with Containment: o NFPA Regulations o Retrofit containment solutions with Legacy fire suppression o Structural costs associated with new fire suppression/smoke detection o Dynamic infrastructure environment

13 New Development In DC Containment Industry Challenges with Containment: o Managing IT equipment growth Aisle Expansion/Consolidation Installation of new cable trays o Equipment decommissioning/re-location Server re-location & new stack buildouts Removal of racks causing voids in containment

14 New Development In DC Containment Industry Challenges with Containment: Figure 3: Rack removal with physical containment 3 existing racks were decommissioned & moved, leaving voids in the physical containment causing hot air recirculation.

15 New Development In DC Containment Developmental Initiatives: o Solution that meets all NFPA regulations o Dynamic, structure-less solution that can fit/evolve seamlessly within any raised floor DC. o Elimination of physical walls for high traffic DC environments. o Scientific approach utilizing turbulent flow technology which requires less cool air distribution. o Elimination of high cost associated with new/retrofitted architectural changes. Fire Suppression Wall replacement/Curtain modifications

16 New Development In DC Containment New Containment Development: o Understand 90% of existing Data Center’s still sit on a raised floor, the goal was to first develop a solution that could integrate seamlessly into the raised floor space. o The development began in QTR. 1 of 2014, after the revised NFPA 75 & 76 standards were released which states the risks and regulations against fusible links & heat-shrink panels found in modern containment solutions. o Acknowledging the physical limitations of existing Data Centers such as inconsistent rack dimensions, floor space & legacy equipment, the goal was to design a much more “transparent” solution, that could achieve similar or greater results to Physical Containment, but on a much more dynamic level.

17 New Development In DC Containment New Containment Development: o New Containment practices utilize a combination of static pressure balancing & turbulent air flow technology, which cuts through the thermal layers and provides directional cold air delivery further up the face of equipment racks, directly impacting the face of the servers. o Structure-less systems are based on science & intellectual properties which eliminates the need to build a room within a room, and evolve within the data center space as the Data Center space continues to change. Figure 4: Structure-less Containment

18 New Development In DC Containment Science in Technology: Laminar Flow o Existing Raised floor cooling systems/tiles utilize standard Laminar Flow vented tiles. o Laminar Flow naturally has a lower stratification due to the inability to break through heat barriers. o Existing Raised floor systems rely on the principal of greater static pressure=greater CFM delivery through the tile. o Increasing the CFM “throw” inside containment simply enhances wasted cooling. Figure 5: Airflow path comparison chart

19 New Development In DC Containment Science in Technology: Turbulent Flow Figure 5: Airflow path comparison chart o Utilizing Turbulent Flow technology in the data center helps maximize the AUE (Airflow Utilization Efficiency) in breaking down the thermal heat layers much more effectively. o Turbulent flow produces air streams in 360 degrees, which allows the servers to pull airflow throw the device with 50% less force at the fan level. o In addition to standard containment results, By improving the AUE, studies have shown you can decrease the usable cooling by 20%.

28 New Development In DC Containment Summary: o Existing Data Center containment practices: Efficiency gains to be had through proper cold/hot air separation. Some applications do not meet new NFPA standard. As Data Centers become much more dynamic, the difficulty in maintaining the integrity of physical containment is an uprising issue.

29 New Development In DC Containment Summary: o New Structure-less containment practices: Efficiency gains while meeting NFPA requirements.
