Technical data
BER3
Power
The entire power supply of the Berlin Mahlsdorf data center is designed as a dual power and emergency power supply with an uninterruptible A- and B-supply and an additional redundant supply for all critical technical building systems such as air conditioning, cooling, ventilation and security systems. In addition, the Berlin Mahlsdorf data center has two 10kV feeds.
UPS systems and associated battery systems are redundant for each A and B supply and are capable of bridging the power supply at 100% maximum load for at least 15 minutes on A or B supply. The generators are auto-controlled to start automatically in the event of a loss of power from one source. The fuel held in reserve is sufficient to provide uninterrupted power to the entire site for 72 hours.
- Redundant 10 kV feeds
- Separate UPS systems (separate, fully redundant A and B supplies)
- Redundantly designed emergency power systems with diesel generators (2 x 2MVA) with 24h diesel supply
- Electricity from 100 percent renewable energy
Climate
- Energy-efficient, redundant recirculating air cooling systems in air conditioning racks
- Enclosure of the cold aisles between the racks
- Redundant air conditioning cabinets and pumps of cooling supply
- Chillers with integrated free cooling and higher-level group control
- Redundant, UPS-supported building management systems (BMS) for monitoring all technical equipment and systems
- Air handling units with central ventilation and humidification and dehumidification
Fire Pro
tection
Only special, non-flammable or flame-retardant materials have been used for the interior of the colocation area in the Berlin Mahlsdorf data center. The individual areas of the data centre are divided into separate fire protection zones. Comprehensive fire suppression and fire protection systems are installed within each area.
- Building fire compartments of fire resistance class F 90 A
- All technical and hardware rooms as F 90 A fire fighting sections
- Secured routes with F 30 /90 A fire bulkheads
- Comprehensive monitoring of all rooms and levels
- Automatic, digital fire detectors and systems
- Early fire detection with VESDA systems
- Automatic gas extinguishing system for flooding the computer rooms
Security
Physical, technical and personnel security at the Berlin Mahlsdorf data center is guaranteed by a six-tier security system, which starts with the monitoring of the data center site and the respective buildings and ends with the control of the colocation area and the individual systems:
- ISO 27001 certified data center
- TÜViT Trusted Site Infrastructure Level 3 enhanced certification
- Video surveillance system for the building in combination with a hazard alarm system
- Secure site boundaries with safety fencing that includes climb over and crawl under protection
- 24/7 security service on site
- Access control via contactless chip card and separation gate
- Closed-circuit video surveillance of doors and entrances with automatic intrusion alarm
- Various sensors inside and outside the buildings for intrusion detection
