Data Centre Düsseldorf II

• ✓ Fire detection system with direct connection to the local fire service
• ✓ Fire protection in accordance with DIN 4102 with an F90 fire-resistance rating
• ✓ 24/7 monitoring by a fire detection system

The rooms and walls of the Düsseldorf II data centre were constructed in accordance with DIN 4102 and meet the F90 fire-resistance classification (fire-resistant). In addition, the individual rooms are divided into separate fire compartments.

A dedicated fire detection system is deployed throughout the data centre and office areas for the early detection of fires. It has a direct connection to the local fire service, which is notified immediately in the event of a fire.

For fire suppression, an argon gas fire suppression system is also used, specifically designed for use in data centres.

• ✓ UPS-protected power supply
• ✓ Emergency generators for extended back-up (including a local fuel supply)
• ✓ “Inner Ring” – dual internal power supply lines

To ensure a reliable power supply, the data centre in Düsseldorf II is connected to the city’s power grid in a ring configuration. As an additional safeguard, the data centre is equipped with redundant UPS systems and diesel-powered emergency generators. This ensures the site’s power supply in the event of a failure in the public power grid. Even prolonged outages can be bridged by on-site fuel reserves and fuel supply contracts. To achieve optimal reliability of the power supply within the building itself, all power lines are laid out in a so-called “internal ring” configuration to provide redundancy. In addition, all racks are equipped with at least two separate 16-A surge protection devices, which provide a high level of protection against hardware failures caused by potential power surges from connected equipment.

• ✓ 24/7 climate monitoring & control
• ✓ Leak Detection System for Cooling Lines
• ✓ Separation of cold and hot aisles

The cooling concept for the data centre in Düsseldorf is based on indirect free cooling, in which cooler outside air is used to assist with temperature control without being directed into the data centre itself. This enables resource-efficient climate control while simultaneously ensuring optimal regulation of the data centre’s environmental conditions (such as humidity). By dividing the technical areas into cold aisles and hot aisles, even greater energy efficiency is achieved, as cooling is provided exactly where it is needed to cool the installed equipment. 24/7 monitoring of environmental conditions, as well as the functionality and integrity of the cooling system, ensures a consistently optimal operating environment in accordance with the internationally recognised ASHRAE standard

• ✓ Highly available & low latency
• ✓ In-house connection to Germany’s largest exchange points
• ✓ Clean IPv4 and IPv6 networks (directly from a RIPE NCC member)

The Düsseldorf II data centre achieves exceptionally high network availability through a direct connection between our backbone and leading national and international network carriers. The Düsseldorf site also features an internal connection to Germany’s two largest internet exchange points, which shortens routing paths and improves network efficiency. This is particularly beneficial for latency-sensitive applications such as VoIP and database replication. To further expand your network infrastructure, our dark fibre connection to the Düsseldorf I site enables the implementation of advanced clustering and failover concepts. Furthermore, as a long-standing RIPE member, we can provide IPv4 and IPv6 addresses and implement sophisticated routing scenarios such as anycast.
