  1. 1. CFD Demo Presentation Trans First Data Center
  2. 2. Environmental Summary• Recirculation of Hot/Cold Air : with the current rack layout, there is a significant amount of exhaust air traveling over the top of the racks resulting in significant hot spots at the intake level….• Unbalanced Static pressure : Most common inefficiency in the data center environment. With the current high velocity in the plenum, there is no ability to control and slow down airflow in the plenum therefore causing low static pressure and weak volumes of CFM through vented tiles……• Lack of real time visibility/temperature monitoring: Currently in the data center, there is no equipment monitoring taking place. Without temperature monitoring at the server level, it is impossible to judge a hot spot or react to a temperature increase leading to a disaster scenario….. *Throughout this CFD report, all points of concern as shown above, will be addressed through our FlowLogix Airflow Management System, and supported by the latest in CFD modeling technology.* 2

CFM Technical Details Current CFM Future CFM• Total CFM Production: 16,000 CFM • Total CFM Production: 16,000 CFM• Total CFM through tiles: 12,800 CFM • Total CFM through tiles: 15,792 CFM• Highest tile production: 562 CFM • Highest tile production: 747 CFM• Lowest tile production: 263 CFM • Lowest tile production: 228 CFM• Average tile production: 362 CFM • Average tile production: 442 CFM Summary: Summary: Currently, only 80% of all the air you are paying for is With FlowLogix installed, 98.7 % of all the air produced by the hitting the heat load. Without control or balance in CRAC units is hitting the heat load. Through achieving the plenum, specific areas in the room are not proper balance in the plenum and implementing proper getting the proper amount of CFM per KW of heat. vented tile management, all the available conditioned air This results in hot spots and higher energy costs. is hitting the heat load resulting in a significant cooling capacity increase. 5

  7. 7. Rack Temperature Details Current Inlet Temperatures Future Inlet Temperatures• Average Inlet Temperature: 77.9 ° • Average Inlet Temperature: 67.2 °• Highest Inlet Temperature: 94.2 ° • Highest Inlet Temperature: 79.5 °• Lowest Inlet Temperature: 65.3 ° • Lowest Inlet Temperature: 60.1 ° Summary: Summary: ASHRAE TC9.9 states that server fans will typically ASHRAE TC9.9 states that server fans will typically respond to respond to a demand for increased air flow as inlet a demand for increased air flow as inlet temperatures to the temperatures to the server reaches or exceeds 77 server reaches or exceeds 77 degrees, consequently degrees, consequently increasing server energy increasing server energy consumption. As you can tell, with consumption. As you can see, currently there many FlowLogix installed, we are able to eliminate any and all hot areas of concern exceeding 77 degrees due to the hot spots. This is the result of more CFM being delivered to the air recirculating through the racks empty U’s and hitting heat loads. There are direct energy savings correlated with the front of the equipment. Also, due to the inefficient the increased amount of cooling and average drop in levels of airflow, we are not directly cooling the rack temperature on the inlet side of the servers. efficiently. 7

Temperature Pattern Details Current Temperature Patterns Future Temperature Patterns Summary: Summary:In the current environment, you can see a large With the proper airflow management solution amount of the heat production is traveling engineered into the data center, you will now see over the top and around the server racks that the cold air and the hot air are completely causing significant hot spots at the intake separated. With the proper vented tile level. Currently, there are several racks management, hot aisle containment, ceiling return exceeding the ASHRAE standard of inlet vents and open U’s being blanked off, all cold air is temperature, therefore the server fans are hitting the servers and all warm air is traveling working harder to try to pull in cold air, through the ceiling plenum back to the CRAC unit consuming more energy. for optimum return air temperature. 9

  12. 12. Environmental Monitoring• Technology Connection will monitor the environment through wire free sensors strategically placed in cold aisles to ensure a constant balance in temperature, and record real-time data. These sensors are monitored through software provided by Technology Connection that will be owned by client and loaded onto a workstation provided by client. When the trending data begins to change, our experts focus on that data to determine what in the environment is causing that change whether it is a new cut out, a change in perforated tile placement, an adjustment to CRAC unit settings, etc… Installed Monitoring Package Includes: Additional Tags for Sale: - Temperature Tags - Fluid Detector Tag - Humidity Tags - Door Tag - M200 International Fixed Reader - Humidity Temperature Tag - Sensor Manager Software - Dry Contact Tag - Sensor Manager License Hardware and software tech support Environmental support Monday – Friday 9:00AM – 5:00PM EST Monday – Friday 9:00AM – 7:00PM EST Phone: 810.588.4369 Phone Support: 866.830.4578 Email: Hardware and software tech email support Sun- Saturday Reports are to be sent to: 12 Email:
  13. 13. ANNUAL CFD MAINTENANCETechnology Connection includes annual maintenance in every FlowLogix installation. Our teamof professionals stay proactive in not only maintaining, but continually working with you tomaximize all efficiencies. We will run up to 2 additional CFD’s per month for the duration of themaintenance contract to insure airflow and energy efficiency is optimized. These additionalanalyses may be used for, but not limited to any of the following purposes: • Addition/removal of equipment in the data center • Energy/Airflow efficiency planning • Data center layout alterations/planning • Disaster Recovery planning • CRAC unit Cycling 13
  14. 14. QUARTERLY HEALTH CHECKSOnce a quarter, Technology Connection will send a cooling specialist onsite to complete CFDgathering of information from your data center. This gathering will include: CFD readings fromperforated tiles or supply vents, floor layout of racks and equipment, and operating set pointsof CRAC/CRAH units. After information has been gathered, cooling specialist will return toTechnology Connection with all gathered data and deliver to CFD engineer. The CFD engineerwill then run an analysis and report findings to client’s FlowLogix representative. FlowLogixrepresentative will schedule a conference call with client to discuss findings from the healthcheck, as well as provide any recommendations the client may need to rectify any issues foundin data center revolving around cooling efficiency. The health check may be scheduled throughclient’s FlowLogix sales representative. 14
