Air conditioning

  • Redundant climate control system with a mixture of direct and indirect cooling
  • Air exchangeby enormously efficient equipment generation of Weiss Air Conditioning
  • Primary cooling by suction and filtration of outside air
  • Mixing of fresh air with indoor air for a constant temperature level
  • 90% of the hours in a year will not require any mechanical refrigeration, since only external air is filtered and mixed.
  • 9% of the annual hours will only require a small amount of mechanical refrigeration.
  • 1% of the annual hours require mechanical cooling, because the outside air is warmer than the air inside.
  • Containment of the cold aisles with sliding doors and roofs to avoid mixing effects: The cold air is targeted and used in the exact amount needed. There is no loss, as only the servers are air-conditioned.


  • Redundant uninterruptible power supply concept with up to 2x1000kVA performance
  • Green Power UPS systems manufacturer Socomec with an efficiency of 96%
  • Transport of energy through low loss power rails with 40% higher efficiency
  • Dimensioning of all components for significantly higher payload to avoid energetically inefficient heat
  • Two separate power feeds through two sub-distributions for each rack
  • 10kW+ power consumption per rack possible
  • Direct neighboring substation
  • 3-stage surge protection: primary protection in the main distribution, medium / fine protection

IP connectivity

  • Two separate fiber pairs
  • Useage of the CWDM technology for high scalability of bandwidth
  • Routing through modern Juniper routers
  • Core Switching by modern Cisco switches
  • Uplinks in either 100Mbit, 1Gbit or 10Gbit
  • Redundant network supply through numerous carriers such as Tiscali International and the German Telekom
  • Peering connections trough various exchangepoints such as DECiX, AMSiX, KleyReX, ViX und NIX.

Access, Security and Logging

  • Biometric access control system with fingerprint reader
  • Logging of all entrances and exits
  • Division in 3 access-restricted areas
  • Separated and secure rooms for batteries, UPS and Power Supply
  • Access only trough 2 channels with security terminals
  • Camera surveillance and recording systems with infrared
  • 24×7 on-site personnel


  • DECiX: 20.000 MBit/s
  • Level3: 20.000 MBit/s
  • Deutsche Telekom – DTAG: 20.000 MBit/s
  • AMSiX: 10.000 MBit/s
  • Tiscali International (TINET / GTT): 10.000 MBit/s
  • 80 Gbit/s total


  • Control of all light and secondary consumers through a central bus system
  • High number of areas of light to reduce energy consumption
  • CO2 fire extinguishers in all areas immediately accessible
  • System to directly alert the technical staff on site and external staff

Server parking areas

  • Optically uniform overall picture by using identical racks
  • 47 U at 1000 mm depth per rack
  • CAT7 cabling
  • Separate power and data lines
  • High Perforation for optimal airflow
  • Closure of open rack units with empty plates to prevent air mixing effects
