EDITOR’S QUESTION Interest in how the industry anticipates sustainably meeting the growing demand for power is increasing. In fact, there is now greater emphasis on putting planning and performance upfront and benefiting from the technological advances in the field, while allowing for the fact that data centre construction is an extremely complex process. Data centre level energy saving: Airflow Management Solutions Airflow Management Solutions (AMS), for example, offer practical answers to these issues. AMS solutions optimise data centre equipment, improve information processing, create a greener data centre and increase flexibility for the data centre manager. ASHRAF YEHIA, MANAGING DIRECTOR, EATON MIDDLE EAST ooling is one of the biggest drains on energy in most data centres. This is particularly true in the high temperature conditions, such as in the Middle East, and the issue is of growing importance as increasing ICT equipment densities create larger data centre footprints and excessive energy demands. C Some simple statistics explain the priority now being given to this issue. At the turn of the century, after years of rapid growth, data centre power consumption crossed the threshold of 1% of all power generated in developed economies. Cooling and UPS losses make up around 35% of total energy consumption in a www.intelligentdatacentres.com data centre, of which general computing equipment power accounts for 50%. In terms of carbon footprint, this growth has elevated the ICT industry into a major contributor to the overall rise in energy consumption and greenhouse gas (GHG) emissions. Today, about 2% of global carbon emissions come from the manufacture and use of ICT – a similar figure to the energy consumption of the aviation industry. Data centres represent a significant and growing share of all ICT- related emissions. The IT industry has realised the economic and environmental significance of allowing this power consumption trend to continue unchecked. Focus, therefore, is shifting from increasing performance and capacity only; to a more balanced view that places a high value on energy efficiency. A wide range of partial and total containment solutions is available to accommodate hot aisle containment, cold aisle containment and rack-based heat containment. Rack containment solutions contain the heat and extract it directly back to the computer room air condition (CRAC) using, for example, a straight Telescopic Chimney (TC). They use AMS for switches and network devices, as well as blanking panels to ensure an effective rack hygiene methodology. The best solutions go beyond the rack and row, implementing room based AMS to further enhance the efficiency and predictability of data centres. Innovations such as CRAC Collars and raiser floor grommets provide additional measures against bypass airflow. In addition to this, individual rack capacity as well as CRAC cooling efficiency can also be improved by using the appropriate solution. Eaton’s aisle containment solutions, for example, include a variety of aisle ceilings and overhead vertical wall systems, aisle ducts and end-of-row doors that alleviate the oversupply of cool air in the date centre.
