Data Centers


DATA4’s design team, made up of Data Center experts, drew on more than ten years’ R&D experience to design its own kind of Data Center, one that can be upgraded in line with technological advances and the needs of our individual customers. Its aim?

  • To guarantee outstanding, robust facilities
  • To manage environmental impact
  • To optimise build times

The trademark of
our next-gen Data Centers


DATA4 buildings are made from reinforced concrete with precast elements for increased strength and resilience. This assembly method enables us to shorten build times whilst guaranteeing consistent structural quality and enabling us to produce features such as single-tenant, column-free rooms with a net usable area from 250 m² to 1,000 m².


From the start, DATA4 freed itself from the constraints of raised access floors (frequently used in clean rooms), facilitating the layout of our Data Centers. This means that DATA4 does not need to deal with cable clutter (network and low voltage cables) under the raised floor, nor any issues relating to floor loading and dust. Cable ducts at DATA4 are fixed to the ceiling, leaving the resin-covered floors completely clear and clean.


DATA4 has patented an innovative cooling system which diffuses air via a ceiling plenum. Cold air is driven from the ceiling to the floor and the hot air created by computer hardware is drawn into cooling cabinets located outside the computer rooms. With no raised floors, the air can circulate freely. This system is designed to adapt to high-density environments, and adjust cold air flow according to the density of each rack.


DATA4 is constantly working to improve its cooling solutions in an effort to reduce PUE.
Accordingly, our datacenters can now benefit from Free Cooling solutions. Free Cooling consists of exchanging hot indoor air for cool outside air, except during summer when indoor air is cooled by a fluid coolant.

DATA4 also uses Free Chilling or adiabatic cooling, in which warm air is cooled by passing through a curtain of water.


DATA4 Data Centers fulfil our customers’ stringent operational and environmental requirements, some of the most demanding on the market

Designed for

Our modules are all independent and can be fitted out and equipped as our customers’ needs evolve.

Data Center

Each Data Center has two Meet-Me-Rooms where customers can connect in complete security.

In each campus, these interconnection rooms are linked to two Carrier Rooms (POP ROOMS), which are in turn connected to several high-capacity telecom loops, with a number of separate entry points. Customers therefore benefit from an enhanced ecosystem of over 70 telecom operators and more than 150 Cloud destinations.

Leverage the benefits of next-gen DC

The primary purpose of all of these efforts is to bring each of our customers more streamlined operations, more modularity, and improved energy efficiency and power density that can meet the needs of new converged infrastructure.

  • Greater hosting capacity: two single-tenant, pillar-free, 1,000 m² rooms, and four 250 m² rooms with the same specifications.
    The is enables us to meet the industrial constraints of customers with rapidly increasing requirements, such as hyperscalers or IT services companies, as well as facilitating the layout of rooms.
  • Ground-floor single-story building to simplify the installation and removing of equipment in the rooms, particularly during the large-scale deployment (more than 1,000 servers) of pre-fitted computer racks weighing over a tonne.
  • Flexible electrical density, from 3 kW to 20 kW per rack, enabling the large-scale roll-out of grid or hyperconverged solutions that require extremely high power densities.
  • Modularity: the optimisation and modularity of our technical equipment provides a cooling and electricity infrastructure that adapts as rooms are filled, reducing energy expenditure.
  • Eco-performance: use of Free Cooling and Free Chilling technology which use outside air to cool buildings (85% of the time on the Paris-Saclay and Milan campuses), thereby reducing consumption of electricity by 20% to 30%.
