[. . . ] Small investments and short amortisation periods are the most efficient method of cooling optimisation. This increase in efficiency is achieved by adhering to the following best practices: Source: IDC, 2007 In 2010 the rate of energy costs in data centre will be more than 30% of the whole IT budget. Thereof the portion of cooling will be 40%. 1. Best Practice: Thermal analysis When using hard facts, all attempts in optimisation will succeed. [. . . ] Unfortunately, increasing cooling output increases energy consumption and your energy bill. Cold Aisle Containment reduces the cooling consumption by up to 30 percent It is essential to hermetically separate the hot air from the cold aisle. This separation can be done reliably with the CoolControl Curtain. With constant cooling capacities, measurements show the temperature difference between the hot and cold aisle are 10-15 degrees Celsius. Depending on the size and environmental specifics of individual data centres, the cooling requirements and energy costs could be decreased by as much as 30%. A separation of the hot from the cold aisle is a standard in modern datacentres. Hot air recirculates into the cold aisle. 3 5 Daxten | Thermal Optimisation Best Practices Play it safe: Test before installing a complete cold aisle containment solution For companies who want to first test the efficiency of cold aisle containment the CoolControl Curtain is ideal. With the curtain, facility managers and IT managers can measure the actual savings and efficiency factors without placing strain on their budgets. Highlights · Cost-saving separation of the hot and the cold aisle (H/CAC) · Prevents recirculation of hot air in the cold aisle · Temperature difference between hot and cold aisle: more than 10° and 15°C · Up to 30% energy savings · Significant increase in cooling system efficiency · Easily installed: in hours not in weeks · No downtime required for installation · Ideal as test installation to measure cold aisle containment results · Compatible with all rack dimensions and vendors 3. Best Practice: Seal openings in the front of 19" cabinets PlenaFill blanking panels and PlenaForm air baffles are indispensable tools that increase the efficiency of hot aisle / cold aisle containment (H/CAC) and for general optimisation of data centre airflow. PlenaFill® blanking panel PlenaFill is an inexpensive solution for sealing the openings between servers preventing recirculation of hot air through the cabinet. The physical barrier keeps cold air at the front of the cabinet separated from the hot air at the back. This prevents hot spots and helps prevent hardware failures or downtime caused by overheating. PlenaFill is critical in separating hot and cold air areas in the server racks, which leads to an optimal cooling efficiencies. When PlenaFill blanking panels are deployed throughout the data centre, cooling units can operate more efficiently resulting in energy savings. PlenaFill blanking panels are made from lightweight non-flammable (fire rated to UL94-V0) material and can be installed into any 19" rack without tools. Each blanking panel is 27U with air tight perforations every 1U which can be torn to create smaller panels from 1U upwards. This patent protected and flexible design along with tool-free rivets makes for quick and easy installation. PlenaFill panels prevent the recirculation of hot air into the cold aisle. 4 Daxten | Thermal Optimisation Best Practices PlenaFill Highlights · Prevents hot and cold air mixing caused by bypass airflow · Fire rated to UL94-V0 · Tool free installation · Each panel covers 27U - separable in 1U sections · Easy to install in all 19" EIA racks · Extremely inexpensive, with high efficiency factor and quick ROI · Cost effective compared to metal or plastic blanking panels. PlenaForm® - Airflow Diffuser and Raised Floor Baffle PlenaForm is an airflow baffle that helps to guide airflow under the raised floor to the server racks. By directing the airflow, cooled air will not escape into unused areas in the raised floor increasing air pressure. Cooled air is directed effectively and efficiently to the openings in the raised floor where it is needed most. PlenaForm is a flexible airflow baffle system which helps to solve dynamic thermal imbalances in data centres. The baffles are die cut both vertically and horizontally in sections that can be removed to correct sizes for installation under the plenum. These individual sheets can be joined together creating impenetrable air barriers. PlenaForm baffles are constructed of a flame retardant polypropylene compound that is inert, non-conductive, and non-hygroscopic with a UL94-V0 rating. A server cabinet sealed with PlenaFill. PlenaForm Highlights · Control and balance data centre airflow · Separate hot aisles from cold aisles · No installation tools required · On-site configurable (width and height) · Fits any raised floor pedestal · Reduces energy consumption and operating costs · An inert, non-conductive and non-hygroscopic material · Flammability rating of UL94-V0 · RoHS and WEEE compliant · An energy saving and thermal tuning tool PlenaForm fits any raised floor pedestal. PlenaForm controls and balances airflow in the raised floor. 5 5 Daxten | Thermal Optimisation Best Practices 4. Best Practice: Optimise airflow through perforated floor tiles To ensure cooled air makes its way through the front of the cabinets and servers with ample pressure, it is necessary to have high density perforated floor tiles. To create an optimal pathway, it is advised to use high density airflow vented floor tiles which allow highplume stratification. While conventional vented floor tiles achieve airflow rates of 20-30%, our solutions provide up to 65% airflow. [. . . ] In spite of these expensive investments, companies suffer from overheating and system failure caused by hotspots in the data centre. The culprits are almost always unsealed or insufficiently-sealed cable openings in the raised floor. The Uptime Institute states that up to 63% of expensive cooled air is lost through unsealed cable openings; this conditioned air is therefore no longer available for cooling vital locations and cabinets where servers are located. Sealing openings puts an end to bypass airflow Conventionally, these problems have been solved by increasing the capacity of the cooling systems. Often companies invest in additional cooling units to maintain air pressure and air flow. [. . . ]
