The 500 m2 expansion, scheduled for completion in the spring, will enable Interxion to continue to meet growing customer demand for colocation space and services, in particular from customers in the fast-growing digital media, carrier, and enterprise sectors. Simultaneously, a number of significant upgrades are being made, including an increase in the data centre's power grid connection to 20 MVA, and the installation of new transformers and new air conditioning systems, bringing total recent investment in the site to €10 million.

The increased power supply, in combination with two new transformers with a total capacity of 3,200 kW, will address the current and future needs of customers running cloud-based applications or virtualised servers that primarily operate high-density configurations and therefore need to maximise the usage of their data centre capacity. The capacity of the air conditioning system has also been increased by 2,000 kW; two supplementary backup generators are being installed and the facility's uninterrupted power supply (UPS), which can be operated in a 2N configuration, is being expanded.

Work has already started on both expansion and upgrades and should be completed in the second quarter of 2011. Once complete, customers will also benefit from enhanced power monitoring systems and building control systems.

"This expansion is being driven by our most technically demanding customers, and as a result it will allow us to maintain our edge in the delivery of highly redundant, highly reliable services with the highest possible power density to new as well as existing customers," explained Peter Knapp, Managing Director, Interxion Germany. "With access to over 50 communication networks as well as the ECIX Internet exchange combined with leading-edge power and cooling, our Dusseldorf facility provides an ideal environment for customer applications as cloud-based infrastructure and delivery become even more widespread."
