CFD analysis - Weather report in your server room

Kelvin Emtech



Back in ancient times, shamans decrypted divine will. To predict meteorological conditions, for instance, they would look to natural phenomena, like birds’ flight patterns. Low flying announced hot weather good for the harvest, say, while no birds swooping through the fields meant crops would be modest. Of course, unfulfilled predictions couldn’t be attributed to the shaman himself who, like all men, was subject to divine whim.

Let’s extrapolate this to our server rooms. The climate in your server room will determine the quality of your harvests: your servers’ proper functioning, your clients’ satisfaction, the physical security of your critical data, and so forth. A poorly conditioned room can make for many bad surprises. While it’s true that no swallow has yet identified a hot spot in a data centre, who knows, understanding sources of heat and figuring out the most effective means to control them may very well be up to the gods.

Unless you’ve using CFD analysis, that is!


Computational Fluid Dynamics creates a three-dimensional representation of your server room and its air flows that takes the thermic data of your information, electric and mechanical equipment into account.

With its variety of colours indicating the hot spots in your server room, a graduated CFD chart makes it easier to identify critical zones that may cause problems over time.

CFD analysis will also provide other reports on the proper functioning of your facilities, including an assessment of air distribution and the percentages of various units’ capacities.


CFD analysis is a starting point for analyzing, designing and planning strategies for your server room.

  • CFD analysis in hand, you will be able to plan the expansion or improvement of your data centre. It will help you:
    • evaluate various architectural elements in your server room (size, shape, floor space, location of cooling modules and server density) and cooling methods (central, in rows, alternating cold and hot aisles, confinement, with or without ventilation ducts, XDV or XDO-type cooling modules, etc.)
    • arrange cooling equipment according to your needs and evaluate the air blocage impact within raised floor.
    • assess the energy consumption of network infrastructures key to your IT strategy

  • CFD analysis also makes it easier to manage how your IT equipment is used and helps you reach objectives, including:
    • Reducing energy consumption;
    • Balancing the strength of your equipment;
    • Improving cable routing;
    • Maximizing space;
    • Carrying out tests on modifications before their implementation;
    • Validating the capacity of the cooling required;
    • Assessing the risk of discovering hot spots;
  • One of the greatest advantages of CFD analysis is its visual presentation. With the help of a 3D coloured chart, it is far easier to lead others to understand the issues of your IT strategy or your infrastructure policy and the technical and financial improvements you recommend. The results are visible, easily understood and can be personalized.


CFD is an invaluable tool for decision-makers in infrastructure and IT committed to optimally managing and developing their server rooms.

  • CIO: equipment management and simulation of your IT strategies;
  • CFO: energy savings and financial planning;
  • CEO: development of long-term strategies and risk analysis.


Thanks to SIXSigma, one of the most effective software programs of its kind, we are perfectly equipped to provide you with CFD analyses of your facilities. These will help you improve your data room management and IT strategies. The Kelvin Emtech team has the training and expertise to help you plan your next moves in your server room or data centre.
