In order to optimize the layout, the network cabling of the main server room has been divided into 10 “islands”, each with 70 racks. The islands each have dedicated switches and routers. The structure of the data center provides maximum security as the server room is isolated in a building made of reinforced concrete. The following elements, batteries, generators and transformers, are separated from the server room and located in special buildings.

Aruba data centers ensure high flexibility and maximum resilience.

The maintenance of the power system is performed using the latest, most advanced technologies. The cooling system, essential in order to run and for the maintenance of the machines, is protected by UPS and is redundant. Furthermore, the safeguard of the cooling power is managed through a partitioning of the airflow avoiding the mixture of cold air of the air-conditioning and heated air of the servers through the use of a Free Cooling system. In order to guarantee the highest level of security, all the batteries are fitted outside of the building which houses the server rooms.

Continuity of the service is guaranteed thanks to:

  • Server rooms powered by two twin power centers “STS devices” (Static Transfer Switch)
  • Physical separation of the power centers from the server rooms (REI 120)
  • Buildings designed for hosting the server rooms and power supply system
  • Physical separation between the power centers
  • Fire-proof walls and doors (REI 120)
