is generally used at the design stage for the analysis of the dimensioning of the installations. Computer simulation provides information on the relationship between the operation of air conditioning systems and variations in the thermal load of IT equipment. With this information, IT and site personnel can optimize airflow efficiency and maximize cooling capacity.
Many different types of equipment and systems are installed in data centers and server rooms. An abundance of subsystems, such as rows of storage area network equipment, network switching equipment, or high-density servers, translates into an abundance of heat sources and cooling systems. Therefore, it is very difficult to understand how these different systems coexist, affecting air distribution and pressure in a room.
Our computer modeling methods, and in particular the computational fluid dynamics (CFD) tools, allow us to analyze these options in detail and to graphically represent the temperature distribution, the propagation speed of the flows and the atmospheric pressure in the different spaces
CFD modeling is not a simple solution to a problem, but a pragmatic application that can help optimize the overall understanding of the project or explore how it is possible to reduce the operating costs of an existing facility. On the other hand, it makes it possible to validate by simulation the climatic dimensioning of a room made up of high density servers in an extreme scenario .
The following are the benefits that can be obtained from using CFD modeling in the design of a server room, or in the analysis of a working data center.
When an EOLIOS engineer with data center design expertise works with your team, they can solve data center design issues. On the other hand, our mastery of the climate management of this type of space guarantees the customer a guarantee of results and the elimination of any disorders.
More importantly, by simulating crisis scenarios the unknown variables and the consequences of problems (supplier power cut) can be avoided from the outset.
By using CFD modeling in the design, power and cooling systems can be optimized prior to facility construction and before investing in a project. CFD modeling allows site personnel and IT staff to validate the functionality of the systems in all crisis situations, thusavoiding the risk of malfunctioning during use.
We study the scenarios of revival of the security equipments, the inertia of loop and the rise in temperature to calculate the maximum temperatures in any point of the space and define the most unfavorable computer servers
The initial investment in CFD modeling pays off many times over. The CFD model allows simple 3D images that are easy to understand by all project stakeholders, which can be analyzed by considering both static images and dynamic videos.
If necessary, the information is protected, because our files can only be played on media players for which a special driver provided by EOLIOS is installed. These 3D color-coded server room maps, showing heat distribution, air velocity and pressure in the space, canindicate areas that need to be refined or simply redesigned. We generally optimize the design of the positioning of the grids on the ground so as to provide a homogeneous flow for all the servers.
Conclusions and recommendations can be made based on the information from the transient scenarios to provide a safe and reliable operating environment for your IT investment. Thus, CFD modeling services within EOLIOS are a great added value for investors and integrators, as well as for end-users, who get a clear picture of the risks their data center is facing.
Data centers are sites where the density of calorie extraction is very high. The pooling of systems, the superposition of server halls, the continuous increase in power of the server racks leads to extremely high heat dissipation on the roof. The dissipation surface being constrained by the dimensions of the building, this results in a very high concentration of air conditioning systems on the roof, leading to a significant risk of power losses, or even cascading systems failing during extreme climatic conditions.
In very strong heat, or during power failure scenarios on the site, superheated air plumes generated by the cooling systems can generate a sharp drop in cooling power, see a a cascade shutdown of systems of roof leading to a generalized fault of the site.
External data center CFD studies make it possible to study the risks of power losses and to optimize the layout of the cooling systems on the roof.
At the same time, it is possible to verify that the fumes (Nox) from the generators are not taken up by the air handling units on the roof, which would lead to air pollution in the offices.
