Radore Data Center

Radore Data Center Inc. (“Radore”) provides services to its customers with a total power capacity of 3.9 MW, high security measures, uninterrupted internet access, technical infrastructure, the most advanced technology in energy and air conditioning.



Radore Data Center, which was established on a total area of 3.020 m² including 960 m² of white area, is located on the -4th floor of MetroCity Shopping Mall in Levent, Istanbul.

MetroCity Shopping Mall, which was opened in 2003, was built on the Metro transportation line. Internet infrastructure throughout Turkey is located on the Metro transportation line. Radore Data Center, which is located at a strategic point in terms of internet, is directly connected to Internet Service Providers (ISPs).

MetroCity Shopping Mall is under control 24/7 via advanced security systems, fire warning, fire extinguishing and smoke evacuation systems. The building is designed by NFPA (The National Fire Protection Association) standards. Measures have been taken to ensure the effective operation of the fire extinguishing system in the event of an earthquake and a valve system that cuts off natural gas has been installed. At the entrances of the building, there are fire brigade connection openings so that the fire brigade can easily intervene in the fire in case of possible situations.


Radore Data Center's power capacity is 3.9 MW total, including white spaces, air conditioning infrastructures, office spaces, and redundant power capacity. Power is transferred to our Data Center through 3 different distribution transformers in MetroCity, two of which are main and one of which is a backup, belonging to Radore. Our transformers are connected to the medium voltage ring network. So that it is backed up by two-point feeding.

The Synchronization Control Panel monitors the power instantly for transitions (generator-generator, transformer-transformer and generator-transformer) and automatically switches in case of failure, low/insufficient voltage or frequency. During the transition, which has a maximum duration of 30 seconds, the UPS infrastructure is activated to provide uninterrupted power. The battery pack of the UPS system has the capacity to supply a minimum of 15 minutes.

Behind the one-to-one redundant and auto-switch transformer system are 3 x 1,875 kVA Caterpillar (CAT) diesel generators, ready and automatically waiting to generate power to the data center in the event of grid power failure. For these generators, there are 3 units of 3.5 ton fuel tanks belonging to Radore, which have the capacity to feed the entire system for a total of 36 hours.

In addition, there is 1 shared fuel tank belonging to MetroCity with 30 tons. In case of network interruption, 10,5 ton fuel tanks feed our generators, while replenishment can be made from the backup tank to the main tank.

The UPS system used in Radore is designed as 5 x (N+1), one of which is a backup.

5 different UPS systems in the data center UPS infrastructure;

  • 1. Group 15x50 kVA Newave (ABB) Modular UPS, (N+1)
  • 2. Group 10x100 kVA Newave (ABB) Modular UPS, (N+1)
  • 3. Group 8x100 kVA Newave (ABB) Modular UPS, (N+1)
  • 4. Group 5x50 kVA Newave (ABB) Modular UPS, (N+1)
  • 5. Group 8x60 kVA Centiel Modular UPS, (N+1)

Data center spaces are provided with double feeds, including A and B power lines for network infrastructure and offices. Power line A is powered by group 1 and group 2, and power line B is powered by group 3 UPSs. In addition, the office and network infrastructure is fed by group 5 UPSs specially allocated to these areas and providing power for a minimum of 60 minutes.

Power to the server cabinets is provided by the redundant "busbar" line. With Busbar lines, cable-hardware chaos was prevented and resilience against natural disasters was ensured. Thanks to the busbar line, technical problems can be intervened more easily and the cooling system works more efficiently.

I n addition to the redundant busbar line, the server cabinets are backed up by two different PDU (Power Distribution Units) fed from two separate UPS groups.


“Free cooling" method is used in Radore Data Center air conditioning. "Free cooling" is an economical air conditioning method that makes it possible to use the low air temperature in the external environment to cool the water used in air conditioning. "Free cooling" infrastructure in the data center,

  • 840 kW x 2 + 870 kW Chiller (external units for cooling water)
  • Sensitive RC air-conditioners providing air circulation inside the data center (internal units)
  • It consists of pumps that provide the necessary pressure to transport water between these two units.

Hot air of 30-35°C trapped in hot air corridors inside the data center is absorbed by precision air conditioning units and cooled to 18-27°C by cold water from chillers. The cooled air is directed directly to the cold air intakes of the server systems. In winter, this process is carried out with natural cold air without using the compressors of the chiller units located outdoors, saving up to 70% in energy consumption. Thanks to power savings, Radore's annual PUE ratio (1,37) can be brought below industry averages.

Radore Data Center has 5,850,000 BTU of active and 2,900,000 BTU of spare cooling power. The entire air conditioning infrastructure is configured as N+1 redundant.

Physical Security

Radore Data Center is monitored digitally and physically 24 hours a day, 7 days a week. It is not possible to enter and exit MetroCity Shopping Mall, where Radore is located, except for authorized personnel outside the hours determined by the mall management. The energy and air conditioning units are located on a different floor from the data center. Only Radore Data Center stuff can enter this area.
