Datacenter

The physical security of the data centre space is a high priority. DUS5 is protected by a multi-level security system. This starts at the full perimeter of the grounds with S-wire and ends with an individual numerical code for the securing of racks and cages. Access to the data centre is only possible for authorised customers with access control. Non-authorised persons can enter the data centre only after approval by eligible customers.

All relevant areas of the data centre are equipped with appropriate archiving of images with camera surveillance. All buildings are also safeguarded with a burglar alarm system; Alarms are reported both internally and at two dedicated alarm lines to independent security companies.

Extensive measures for fire protection are in place. A highly sensitive fire alarm system monitors both the data centre and the office space. In addition to that fire detectors with suction technology which can detect fire earlier are installed in the data centre.

In the event of fire, argon gas extinguishing systems now provide nondestructive extinguishing of IT and technology. Data loss by fire is not possible. The local fire department will also be informed immediately about a fire through a direct activation of the fire alarm system. All data centre surfaces correspond to at least the fire protection standard F90, surfaces in the Lampertz security room even to the standard F120. All rooms as fire section are designed to prevent the spread of fire.

Redundant climate control systems in the data centre provide reliable cooling of the IT systems. Redundant air conditioning units provide a constant temperature between 19 and 24 degrees and a controlled humidity in accordance with the ASHRAE standards for IT.

Through the use of free cooling and cold/hot aisle segregation, air conditioning working highly efficient and environmentally friendly. The entire air conditioning is monitored around the clock on the building management system and separate monitoring systems in the data centre. Leakage sensors and pressure monitoring report leaking coolant immediately.

A ring-shaped connection of the medium voltage network of Stadtwerke Dusseldorf provides the own transformer equipment in data centres and in the event of failure of a power connection also ensures the power supply through the network of the energy provider. Should there still be a power supply failure, the preheated diesel generators become active immediately and update the battery-backed uninterruptible power supply existing in each data centre range.

All infrastructure systems such as air conditioning, power supply systems and security systems are monitored and controlled by a building control system. A second, independent system also checks all relevant parameters and immediately informs our technicians and service providers in the event of a fault.
