Information Technology Managers are faced with many challenges in the daily operation of data centers.  The success of their effort, however, is heavily influenced by operational variables in the cooling systems which they have little or no control over. Merely dumping cold air into the data center is no longer acceptable. This results in ineffective cooling and wasted energy. Rooms averaging over 300 watts per sf are now the trend with individual equipment rack loads exceeding 24 KW  over 8 sf becoming more common. Fresh design approaches are required to meet the present and future needs of data centers and not merely the scaling up of outdated designs. System design philosophy should provide for the scaling up of cooling capacities, including the use of chilled water,  to meet future heat densities at a reasonable cost and with minimal disruption of existing operations. Data centers are evolving to require integrated solutions involving input from facility designers, users equipment suppliers and system operators. Ackerman-Practicon is possibly unique in that we have several high density designs at more than 300 watts/sf in operation. AP design experience includes the Terascale Simulation Facility located at Lawrence Livermore National Laboratory. Rated number one in 2005 among the top 500 data centers world wide, this  facility contains 48000 sf of super computer space at  320 watts/sf, 7000 tons of refrigeration and 25 megawatts of electrical power to the site.. Additional information on this project can be found at:              http://www.llnl.gov/asci/tsf/ Control of the  data center air distribution systems must extend inside the data center to provide an environment that will react to changing operational conditions over time. Uncontrolled air distribution and simply moving more air is a thing of the past. The air distribution systems must be able to react to the following dynamic conditions: Changing computing requirements. Range of heat densities across the data center. Range of supply air temperatures and pressures across data center. Concentrated equipment heat loads. Ackerman-Practicon tailors the design of the air distribution and control systems with flexibility and scalability to meet future requirements. Users and operators would have the capability to optimize the performance of both the data center equipment and mechanical systems. We also provide mechanical performance audits for existing facilities and support for the commissioning of new facilities. Some of our design strategies to optimize the air distribution systems within the data center include the following: Temperature controlled air delivery systems. Cold cell/ hot aisle configurations.  Customized HVAC equipment/controls for increased operating efficiencies.  2-Story air distribution options. Computational fluid dynamics modeling. A fully designed air distribution and control system offers users the following benefits: Reduced capital costs and energy costs. Operational flexibility and scalability. Full utilization of cooling capacity. Elimination of  equipment hot spots. Reduced temperature related equipment failures. Increased cooling system reliability. Increased equipment compaction rates. Extended data center life. Increased energy  efficiency. Ackerman-Practicon provides communication systems design for active and passive equipment. Our team can assist in programming and layout of all systems for next generation concepts. Our experience with corporate and government clients allows for leading edge solutions.
