Redundant Solutions with Two Data Centers

Reliable and Compliant Data Center Footprint in Hannover, Germany

The Hannover data center is the basis of our high-performance and reliable solutions.
Separate Fire Zones are implemented in 2 data centers at a safe distance of 70 meters and interconnected by network and cable shafts. The building sections are entirely autonomous, and each has a redundant power supply. In addition to the four standby power supply systems, the main building sections each have a ring connection to two different power grid substations. The lightning, fire, and sabotage protection concepts of the data center are designed so that one part of the building can be completely shut down without impacting the HA solution.

The infrastructure remains operational even after a fire, an aircraft crash, or an explosive attack on one building. For example, applications can be designed as cloud infrastructure with VMware either in active-active with load balancing or active-passive in failover operation over separate fire sections with a distance of more than 70 meters. The system architecture of a private cloud solution with cross-connects spanning over two fire zones in the data center. Optionally, the subdistributions of the total of 4 colocation footprint areas of the data center can also be cross-connected between two separate fire zones.

In this case, the fail-safety on the relationship level can be designed to correspond to the highest safety standard: Tier 4 (Tier IV). We can also offer data center space and colocation space compliant to the Tier 2 (Tier II) and Tier 3 (Tier III) standards.

 

Safety distance

Critical fire zones are separated from each other by a safety distance of approx. 70 m and interconnected by network and cable shafts.

Protection concept

The lightning, fire, and sabotage protection concepts of the data center are designed so that one part of the building can be completely shut down without impacting the HA solution.

The benefit of multiple data center locations.

The infrastructure remains operational even after a fire, an aircraft crash, or an explosive attack on one building. For example, applications can be designed as cloud infrastructure with VMware either in active-active with load balancing or active-passive in failover operation over separate fire sections with a distance of more than 70 meters.

The decisive advantage over classic failover scenarios across two data center sites is the availability of specialized staff on both locations to ensure prompt de-escalation of incidents. The administrators can service both data centers; there is no need to fall back to third-party providers to the detriment of the service quality and speed.
