3 DirectAire The High Density Directional Airflow Solution for Data Centers Unlike other grates the DirectAire angles the airflow toward the equipment achieving a % Total Air Capture (TAC) rate by a standard server rack. This means % of the airflow delivered through the grate is entering the face of the server rack, providing the highest cooling capacity and energy efficiency of any grate on the market. The elimination of bypass air saves operating expenses in existing facilities and reduces capital expenditures on cooling equipment in new facilities. DirectAire s superior load performance is ideal for retrofit and new construction, easily integrating into your existing raised floor system.

H O static pressure. More importantly each vertical vane has an angle of deflection at the top to direct the airflow towards the server rack. Unlike other grates the DirectAire s angle of deflection allows the equipment to achieve a % Total Air Capture Rate. This means % of the airflow delivered through the grate is being captured by the server rack for cooling, compared to typical airflow panels which only deliver -% directly to the rack. The DirectAire s ability to direct air where it s needed most makes this panel ideal for high density applications with cooling capacity of up to.kw per Rack.

Improve Data Center Financial Performance DirectAire maximizes energy efficiency and the overall capacity of any new or existing data center. The precise delivery of air to the face of the rack reduces by-pass air allowing new facilities to in-turn reduce the number of CRAH units. Retrofits can set CRAH units with fixed speed fans to standby mode or adjust variable fan drives to operate at a lower static pressure, saving energy. Likewise the % capture rate eliminates the need for a full containment system. The facilities overall cooling capacity will also be improved allowing for the addition of equipment without the capital investments on infrastructure. Standard grate requires more static pressure due to bypass. DirectAire cools the same rack with less static pressure. Strong & Durable Cooling capacity and energy efficiency are just the beginning of the DirectAire s impressive characteristics. With a lb Rolling Load the DirectAire s all steel construction eliminates the need to move heavy equipment through the hot aisle by providing the strength to move equipment over the airflow panels. In addition to high rolling capacity the DirectAire features a Design Load of lbs with a Minimum Safety Factor >. meaning this panel has been designed to handle the most demanding load applications.

5 Total Air Capture & Data Center Airflow Total Air Capture (TAC) rate refers to the amount of air delivered through the panel that is then captured by the server rack placed in front of that panel. The black box below represents a standard x server rack. Lines have been added to show the three zones of the server rack. Zone represents the bottom of the rack closest to the floor and Zone represents the top of the rack farthest from the air supply. You will notice that the DirectAire grate delivers % of it s, CFM at. H O to the face of the server. Furthermore you will notice this airflow is spread evenly across the three zones of the rack. TAC Reduces Total Airflow Requirements The total airflow required for cooling the same size data center is significantly reduced through the increased TAC rate provided by DirectAire. This reduction in total airflow has a dramatic effect on the fan energy required to move air throughout the data center. CFM HO CFM Captured % TAC Zone CFM % Capture The chart shows over a % reduction in the Total CFM required to cool a typical data center with a MW load using a typical grate compared to DirectAire. Zone CFM % Capture Eliminate the Burden of Airflow Containment Containment systems in a data center come with many challenges including fire code requirements, service distribution restraints and limited flexibility. Unlike other panels which throw air straight up in a vertical plume the DirectAire s angular throw evenly distributes the majority of the air it delivers directly to the face of the rack providing effective containment when used in conjunction with best practices. Zone CFM % Capture The smoke test above shows directional airflow path and air capture rate per zone at the face of a standard x server rack. DirectAire s %TAC rate enables you to gain near peak airflow without containment. Typical airflow panels require containment systems to ensure maximum airflow to the racks.

6 Cooling Capacity & Load Performance DirectAire s ability to deliver high volumes of air directly and evenly across the face of the server rack gives it the unique ability to handle very high density equipment. The table below lists cooling capacities per rack based on a mathematical calculation for systems with and without containment using the following formula (CFM x Total Air Capture %) / (CFM needed to cool ºF ) = kw per rack. Laboratory testing was conducted using heat banks to measure the cooling effectiveness and verify the calculated kw/rack heat loads.

7 Improve Your Financial Performance DirectAire Offers Energy Efficiency, Capital Investment Reduction and Excellent Payback The energy savings realized through the use of a DirectAire grate is made up of two components. The minor component is gained from the grate s large open area which allows the same airflow at a lower static pressure. The second and larger component, is realized through the DirectAire s % Total Air Capture rate. A typical uncontained cold aisle configuration assumes more than % of the air delivered will bypass the equipment. The DirectAire reduces this bypass air to less than % resulting in tremendous energy savings. The potential for enormous first cost savings are available to new construction projects due to DirectAire s % TAC rate. The virtual elimination of bypass air enables the facility to operate safely using less CFM and therefore allowing for a significant reduction in the number of CRAH units required.

9 SmartAire Efficiently Manage Diverse & Variable Loads The data center is in constant flux. Load diversity between racks and variable server loads are the norm. Managing airflow into the data center space is key to achieving reliability. New demands to reduce energy consumption in the green data center require a fine balance to ensure proper air flow to each rack during peak hardware operation, while not over-cooling partial load and idle states in a diverse environment. Tate s SmartAire electronically controlled variable air volume damper used in conjunction with DirectAire adjusts the amount of air to meet the specific needs of the rack it services. Sensors mounted to the front of the rack control the VAV damper ensuring the proper inlet air temperature is maintained on a rackby-rack basis. This flexibility can help effectively cool facilities implementing virtualization, cloud computing and idle server shutdown strategies while saving energy.

The load diversity results in differing airflow The solution has been to provide sufficient air to accommodate requirements per rack. Efficient cooling requires that the airflow the peak energy demands of the rack, resulting in wasted delivered to each rack be matched to that rack s demand. bypass air and over-cooling during all less than peak conditions. Each rack in the data center however is a constantly changing entity, with each add, move or change modifying the load. This of course changes the rack s airflow requirements, resulting in the need to manually adjust the airflow delivered from each panel to properly and efficiently cool the rack. To further complicate matters, the load in the rack may change due to processing demands of the hardware at a given time. This load variability has been driven by hardware that has become more efficient over time, increasing the difference The chart above shows the variability in the energy consumed for the load at the rack level for a Cloud Cluster. between idle power consumption, and % utilization.

11 Heading SmartAire Effectively Solves the Problem Sub-heading (optional) SmartAire adapts technologies readily found in commercial office applications to create a solution for controlling airflow delivery to the racks through the use of a variable-air-volume (VAV) device installed below each airflow panel. Each panel & rack tandem can be thought of as an individual zone. SmartAire measures the incoming air temperature at the face of the rack and adjusts the flow to ensure that the temperature at the face of the rack is never above the maximum allowable set point provided by the user. When deployed using best practices, the system is able to virtually eliminate bypass air, and account for any local temperature fluctuations.

12 Achieve the Ultimate in Financial Performance SmartAire Takes Efficiency Even Further The energy savings component of SmartAire is achieved through it s effective management of diversity and variability. Virtualization is a common server management strategy to increase the computing power of existing hardware and to save energy. Virtualization often leads to variability and denser racks with wider ranges in demand between high utilization and idle states. SmartAire s ability to automatically and instantaneously adjust to distribute exactly the right amount of air needed to cool the equipment allows the CRAH units variable fan drive to adjust more accurately for optimum efficiency. SmartAire also handles load diversity without over-cooling lower density racks saving energy. Deployed at the rack level rather than by row, SmartAire can reduce the amount of airflow to low density racks allowing more airflow to be delivered to high density areas without increasing underfloor static pressure or making costly equipment purchases.
