Data center CZ1, Czech Republic

Surface area:

1,500 m²


More than 5,000 physical servers


The data center has an uptime of 100% since its launch in 2004.

Power supply:

1 Megawatt of electrical power is provided to the servers, with a complete redundancy thanks to two separated Power Centers. Each Power Center has the capacity to power the data center on its own, even at full capacity, and is equipped with double conversion UPS systems with high energetic efficiency (2N type redundancy).

Separated buildings for general power supply and UPS battery systems:

In order to ensure a maximum security level for server rooms, power supply systems and UPS batteries are placed in 2 dedicated buildings, physically separated from the data center.

Redundant power generators:

The data center is equipped with autonomous power generators with underground fuel tanks able to provide energy to the entire datacenter even at full capacity. These generators start providing energy after the batteries from the UPS system.

Green data center:

We have put a lot of attention in the optimization of the data center in terms of energy consumption. The entire cooling system of the server rooms has been equipped with highly effective direct expansion appliances, linked together in a network and optimized by a system able to adjust the level of cooling provided.

The building is also equipped with a free-cooling system. Through the use of colder outside air, meticulously filtered and corrected at humidity and temperature level, we are able to reduce the use of heat pumps and thus reduce the energy consumption and the impact on the environment.

Redundancy of air conditioning systems:

The air conditioning systems in server and power rooms are made of multiple redundant appliances able to guarantee a perfect functioning of the cooling even in case of simultaneous unit failures.

Bandwidth of 30 Gb/s:

The data center benefits from a bandwidth of 30 Gb/s, provided through fiber-optic connections to the most important national and international service providers and to the main network access points (NAP).

Physical security:

The data center has automatic fire detection and suppression systems, working with FM-200 gas, harmless for the staff and the electronic appliances.

The building is also equipped with an intrusion alarm system installed in each alley and connected to the double identification access control system. Finally, a closed-circuit television system (CCTV) enables us to monitor the entire building.

Monitoring 24x7:

The data center is controlled by a monitoring team 24/7 and 365 days a year.

ISO 9001 and ISO 27001 certified:

The data center has been granted ISO 9001:2016 certification for quality and ISO 27001:2014 certification for security.
