NEW DATA CENTER
IN ANGOLA
THE NEW ITA DATA CENTRE PROJECT, CALLED DATA CENTRE 2, IS A BUILDING BUILT INSIDE THE ITA COMPANY COMPLEX.
T he New Data Centre is an extension/expansion of Data
Centre 1, which is intended for data processing and storage.
The building, with a footprint area
of 1,450 m2, has three floors and is composed of a reception, lobbies, a testing room, technical areas, UPS rooms, crisis rooms, sanitary facilities, freight elevators, unloading platforms and emergency stairs.
The exterior walls are made of exposed concrete with visually attractive surfaces, created by the careful stereotomy of
the formwork, the texture given to the concrete and the creation of moulded patterns, coated on their interior face by a sandwich panel with rock wool.
The technical areas were adequately covered with technical flooring, walls in fireproof sandwich panels with acoustic characteristics and ceilings in removable metal plates.
The technical area of the roof houses all the necessary equipment for cooling and air renewal of the Data Centre. It is composed
of two reinforced concrete walkways with rain water drainage channels.
The entire building has access control, CCTV, fire sealing, fire and intrusion alarms, and fire extinguishing equipment.
The fire protection measures are guaranteed by smoke removal and gaseous fire suppression systems. The building
is equipped with 13 gas bottles, totalling about 2,000 kg of NOVEC, available to ensure fire extinction. The entire system is fully automated to ensure the protection of the equipment.This being a technical building, the air conditioning is specific to this type of solution and is carried out by close control air conditioning units. The Data Centre is equipped with 12 units with a total air-conditioning power of 720 kW, with electronic control of temperature and humidity.
The Data Centre has over 170 racks installed, enabling space rental for at least 160 clients to accommodate their equipment. Communication with the outside is guaranteed by more than 9 km of fibre-optic cables.
