Data Centre Budapest

The Data Centre of T-Systems Hungary is located at 13 Asztalos Sándor Street, Budapest. It is open to customers on 14,400 sqm on two floors. The location of the complex ensures physical access to the established backbone of data transmission and telecommunication service providers and meets customers’ logistics requirements.

Data Centre Budapest In order to provide maximum security and availability, the building and the built-in service equipment was implemented in line with the so-called N+1 philosophy: in addition to the required system (N), at least one reserve (+1) system is always available for automatic supply in order to maintain an appropriate service level.

To route data communication and mechanical services, the internal structure of the complex is covered by raised flooring bearing 2 t / sqm distributed load and minimum 60 cm height to allow cooling and a hidden and secure void for the passage of electrical and data transmission cables. Transport between the individual floors is performed by a 2 t hydraulic freight elevator. The ramifying technical systems of the Data Centre are supervised by operating engineers working in an uninterrupted time schedule around the clock. The building surveillance system is a great help, as it monitors more than 31,000 measuring points, thus in addition to information on customers’ consumption, data may be queried of all electrical and mechanical systems, and in the event of a fault, alert and escalation are also allowed.

Electrical System

Medium-voltage electricity of maximum 22 MW capacity is supplied to T-Systems Data Centre by four operational and one reserve feeds. Electricity is supplied to the building by its own transformer stations, and the system is protected from eventual outages by uninterrupted power supplies (UPS) and a system of generators. In the event of a mains current failure, ten generators secure 22 MW aggregate uninterrupted electricity supply under the N+1 philosophy. At full load, their operation is ensured by approximately 240,000 l of reserve fuel stored in four separate containers. As the generators are located in pre-heated and noise insulated containers, they start operation no matter how adverse the weather conditions may be, and within maximum 3 minutes of co-ordinated activity, they can ensure continuous operation. To close this time gap, central UPS systems have been set up to provide protection to each consumer by two completely separate supply systems in accordance with the N+N philosophy. Under full load, the batteries in the system ensure 8 minutes runtime for the generator systems to transfer load. The redundant bus systems running on the corridor ensure two separate feeds for any single consumer.

Air Conditioning System

According to the N+1 system philosophy, the precision air conditioners that regulate the temperature and moisture content of customer areas are connected to a closed-circuit pipe system, used for cooling air in the machine rooms. Primary circle cooling is performed by heavy-duty liquid coolers, with the coolant transported to the equipment by a redundant pump system. Fresh air is ensured in the building by high-capacity air handling equipment, which clean, pre-heat or cool the dust-free fresh air blown into the premises. On customer areas the temperature is maintained at a constant 22 C° ± 2 C°.

Fire Alarm and Fire Fighting Systems

A VESDA (“very early smoke detection apparatus”), operating with laser detectors and continuous air sampling, has been installed as a fire alarm. If fire is detected, fighting by inert (nitrogen-based) gas starts within 30 seconds. Fire-fighting is started by pressing oxygen out of the room, thus the oxygen content of the air is reduced to the level insufficient for fire, and this way its spread is prevented. The benefit of the system is that it does not use any environment polluting agent during operation.

Security

The Data Centre is completely protected against external penetration by an anti-burglar system, the first elements of which are concrete poles to prevent penetration and hydraulic traffic bollards along the public road. Security guards watch the ambient environment as well as the most important premises in the building via a closed-circuit television network in a round-the-clock service. The recorded images are archived and may be retrieved. The critical points and routes in the building are checked regularly and in person during logged patrolling. The most important premises are also protected by biometric IDs. Access to the areas reserved for customers is allowed by active cards and may be secured by custom PIN codes.

Telecommunications

Access to the Data Centre is provided by numerous telecommunication service providers. The providers are present in the Data Centre with optical inputs, which allow the use of wide bandwidth, highly secure telecommunication services.
