Berlin Deutschland Europe EU
Main Power
Dedicated underground 10kV cable feeds to 3×2MVA, (4×2 MVA ultimate) 10kV/400V transformer substation
 
Generators
One (three ultimate) x 2MVA diesel-driven emergency power generators giving 2 MVA (6 MVA ultimate). Automatic start in less then one minute to feed 100% of the facility. Generators tested monthly. Fuel storage (Diesel) for 24 hour continuous operation at 100% load. 24×7 agreement with local fuel supplier
 
UPS
Two (three ultimate) x 625kVA Hybrid Rotary UPS modules providing 625kVA (1,250kVA ultimately) total output with N+1 redundancy. 15-minute battery autonomy for each UPS module. Dual-redundant A and B distribution strategy. Underfloor power track distribution system
 
DC
48VDC power system. 400A “A” + 400A “B” expandable to 2385A “A” + 2385A “B”. Dual-redundant “A” and “B” systems with dual redundant “A” and “B” distribution. Four hours of battery autonomy. Underfloor direct A and B feeds from PDU to fuse panel
 
Closed Circuit Television (CCTV)
CCTV monitoring and recording of all access points and circulation areas
 
Environment
750W/m² average cooling capability over the gross space. Temperature regulated overall to 21°C+/- 2°C. Humidity regulated overall to 50%RH +/- 10%. Technical areas positively pressurized to minimize dust ingress

Fire Strategy
Use of non-inflammable and low-smoke, zero-halogen materials where possible
No storage (especially of flammable
materials) within technical space
Building split into sealed, independent, fire compartments
Very Intelligent Early Warning (V.I.E.W.) detection
Smoke extract system activated by fire alarm
Double-interlocked pre-action dry pipe sprinkler system
 
Security
Remote 24×7 security monitoring
Full electronic access control system, based on proximity cards with photo and PIN keypads
Biometric palm-scanners for colocation areas
Locks on colocation suites and cabinets
Intruder detection system on escape and riser doors
 
Building Monitoring System (BMS)
Local Operations and Control Centre. Network monitoring system with critical alarm repeating to Regional Management Centre. 24×7 local monitoring and logging of temperature and humidity conditions and alarms
Full perimeter under-floor leak detection linked to building monitoring system.
 
Telecom Infrastructure
Facility is designed to accommodate standard rack/cabinets of 2,200mm nominal height
Power is normally distributed under-floor; fibre and copper cabling distributed overhead (fibre within a managed containment system, copper within a heavy-duty ladder rack system)
Fibre entry to the building via two independent points
colocation hybrid cloud cabinet suite
Physical
Minimum floor-to-ceiling height: 3,100mm from top of raised floor. 850mm raised floor height. Raised-floor loading 30kN/m². Structural Floor Slab: Ground Floor—30kN/m²; First Floor — 8kN/m²
 
General Facilities
Dedicated loading area—delivery hours 8.00–18.00 (Mon to Fri). Customer test room (68 m²) and storage area (48 m²). Goods lift—1.4m wide x 2.6m high (maximum load 2,500kg)
