C O L D A I S L E C O N TA I N M E N T The Next Generation of Data Centre Containment Partial Containment By Lars Strong, P.E., Senior Engineer, Upsite Technologies Introduction Lars Strong takes a closer look at effective airflow management for your data centre. Containing hot or cold aisles in computer rooms has become almost as standard a practice as installing grommets and blanking panels. The 2013 Uptime Institute Data Centre Survey shows 72 per cent of large facilities (>5000 servers) and 53 per cent of small facilities (<1000 servers) have installed hot or cold aisle containment. While the benefits of containment are well known, until recently the solutions available have had significant limitations: high cost, inflexibility to a changing environment and disruption of operations from construction activities required for installation. Perhaps most significantly, in many of the containment installations that have occurred, full containment, whether cold aisle or hot aisle, were not necessary to achieve the desired airflow management results. Fortunately, data centre managers can now consider modular partial containment. While the applications may vary, the core airflow management benefits of all forms of containment are similar and well documented: reduced hot spots, reduced mixing of hot and cold air, increased rack density, and energy savings as a result of being able to adjust CRAC/CRAH unit airflow rates and temperature settings. To some degree, all solutions provide these benefits. The prudent consideration for any data centre manager evaluating containment solutions for their computer room is: what form of containment will provide the desired airflow management benefits while keeping cost and impact on operations to a minimum. The newest form of containment— modular containment—has been engineered to provide the core benefits of traditional containment solutions, but with the flexibility of ‘modules’ that are installed on an individual rack basis. This allows great flexibility, as any row can be scaled up and down as needed. Modular containment also addresses the issue of inconvenient installation with a user-friendly, non-intrusive, magnetic application that can be self-installed in just min ]\ˈHXYۙ]X
