Massive underground data centre opened in Norway

Thu 11 May 2017


The Lefdal Mine data center, an underground facility with 120,000 square meters of available white space, has officially opened. Phase 1 of the buildout is complete, and the initial customers will go live in Q3 2017.

The ‘mountain hall’ data center was designed as a modular, scalable, and secure facility, constructed underground.

Located in western Norway in the Sogn og Fjordane region, the data center consists of six underground levels divided into 75 separate chambers. The 1300m main access road is a spiral, providing access to each of the six underground levels. A main avenue on each level provides direct access to the 75 chambers located on each floor.

The unique location and design has resulted in what the company claims to be ‘one of Europe’s most cost-effective, secure, green and flexible data center facilities.’

The Lefdal Mine data center claims to have one of the lowest total cost of operations (TCO) in Europe, stating that customers can reduce operating costs by up to 50% over other data centers. The reasons behind the remarkable cost savings are the low cost of power in Norway, and the use of 100% renewable energy provided by hydropower and windmills.

Additionally, the Lefdal Mine data center was designed with an innovative cooling solution that uses cold seawater from a nearby fjord as a cooling source. The cold seawater runs through a heat exchanger which then cools a closed fresh water circuit.

This is expected to provide a power usage effectiveness (PUE) of 1.08 to 1.15, varying on the configuration and scale of the client network.

Jørn Skaane, CEO of Lefdal Mine said, “We acknowledge the increase in demand for high secure data center capacity, and foresee a future where governments and private sector invest in solutions guaranteeing uptime and proper solutions for back-up and disaster recovery.”

With guaranteed redundancy, the Lefdal Mine data center can connect to London with only 17 ms latency, and to Frankfurt with 20 ms. Traffic to mainland Europe will be routed through the UK, Sweden or Denmark.

The facility was designed to be highly secure, with only two points of entry to the underground location monitored 24/7 by trained security staff, bolstered by three-stage authentication and intelligent camera systems. Additionally, fire detection and suppression systems were designed for early detection and fast response.

Because of its unique design, clients may elect to use the data center as a single location or dual site, using different streets or levels of the mine for two separate data centers.

Initial customers include Innovo Cloud, LocalHost AS and Fortuitus AG.
