Simulation in 6SigmaROOM
ALPHA-Numerics GmbH is a supplier and
service provider in the field of CFD-supported
temperature simulation.
1. We distribute the products of the
manufacturer FutureFacilities as exclusive
dealer and train users in the use of the
software 6SigmaROOM. In addition, we offer
a German and English language hotline for
our licensed customers (Germany, Austria,
Switzerland, Italy, Spain and Eastern Europe).
2. Through our parallel offer for order

Electronics cooling in general
We have been working as specialists for electronics cooling for over 20
years and support all electronics industries as a service provider, from
device development to computer center planning or troubleshooting in
existing data centers. For this we use the latest CFD technology
(Computational Fluid Dynamics), the industry-specific tools of the
London-based company FutureFacilities.

Construction of a digital twin
Floor plan
To start a data center modelling, we need a floor
plan of the architectural spatial dimensions. By
adding additional information, such as a raised
floor with 0.66 m panel grid and 1 m height, the IT
room can be modelled in 6SigmaROOM even
with ramps, doors and, if necessary, wall
openings for cold clamps.

Construction of a digital twin Cable routes Already with the modeling or later, when the ACUs, PDUs and racks are in the room, the cable routes and the piping of the ACUs can be added. Here we need the route width, height and filling degree in %, if the cable routes are not closed but consist of open baskets. The position can be in the subfloor, in the room or in the ceiling. The floor or room swirl diffusers can also be modelled and positioned according to the specification. In the case of perforated floor plates, an opening ratio and hole geometry would also be sufficient to ensure the correct pressure drop across the plate.

ACUs – Air cooling units
In the planning phase it is possible for us to define
no-name units for conceptual design with fixed or
adjustable volume flow and supply air temperature,
or to position the ACU via the manufacturer
database using drag & drop.

1 *. An object based on limited information, e.g. manufacturer, model, cooling capacity, airflow with other properties
based on estimates
2 *. An object based on a product brochure with some minor estimates of the most important features
3*. An object based on a published data sheet or data book, with published data for all key characteristics and some
estimates for detailed characteristics
4 *. An object that is based on a published data sheet or data book and whose estimated values and key characteristics
have not been verified by testing
5 *. An object based on information provided directly by the manufacturer for all characteristics

manufacturer-specific racks or mounting carriers can also be positioned

For each rack, a preset power can be defined, or IT-specific, each
device with XY % load at maximum power can be defined.
For this purpose we also offer the import of the common DCIM tools for
existing data centers. With access to our IT library, this import can
automatically populate the racks and assign a load.

6SigmaACCESS
6SigmaAccess is a browser-based tool that reduces the capacity
planning process from weeks to hours by consolidating critical
data center resources into a single view. 6SigmaAccess is
supported by our advanced CFD software, 6SigmaRoom, and
enables you to meet future capacity planning needs by predicting
the impact of any change in your facility.
6SigmaAccess allows users to view a digital twin of their active
data centre in their browser. There they can test potential
movements, additions and changes to their IT. Suggested
changes are automatically forwarded to 6SigmaRoom where DC
engineers can investigate, analyse and mitigate potential
problems. The entire workflow is designed to keep you one step
ahead and eliminate the risks of physical implementation.
