DC1-Stavanger is a former NATO ammunition storage facility converted into a unique high security colocation data centre with 13 600 m2 technical/white space initial availability. The infrastructure has been designed to be expanded up to 26MW. The main data centre comprises three 2 storey concrete buildings built within the mountain.
Details below illustrate how we deliver the robust and efficient ‘state of the art’ Tier lll facility.
The site is fully operational with clients including financial institutions, health, IT companies and government.
DC1-Stavanger has multiple grid supplies each fed from multiple hydro electricity power plants. Outstanding robustness of supply is the result (estimated 99.99997%) with even further additional levels of security in terms of N+1 prime rated generators. Phase 1 expandable to 26MW.
"Red" and "Green" cooling stations
DC1-Stavanger has a cooling source available from an adjacent deep water fjord. At levels below 75 m depth the water temperature is stable at 8 oC (46F) all year round. Our cooling system uses gravity effect to bring the cold water from a depth of 100 m to the data centres cooling station without using any energy.
The cooling solution (including cooling station, chilled water pipework and pumps) is fully duplicated providing an N+N solution. Because there are few moving parts (circulating pumps) the solution is extremely robust and reliable. Server rooms will have available N+N chilled water under the raised floor. In row cooling will be installed to client specification using hot isle technology. Standard power densities from 2-6 kW/m2, bespoke solutions can be accommodated up to 20 kW/m2.

We have server rooms from 50 m2 in size up to 1550 m2 for a single room and multiple rooms are available.
Bespoke solution: power density, cooling, security level etc. can be delivered according to customer requirements.
DC1-Stavanger’s location inside a mountain enables the facility to be made air tight and hypoxic air ventilation used as a fire suppressant – A fire can’t occur because the combustions process does not receive enough oxygen which is reduced to about 15% (from 21%). This corresponds to an altitude of approx. 3.000 m. Oxygen level is constantly monitored with display screens in every client room ensuring the system is fully operational at all times. The mechanical equipment used to achieve this is duplicated N+1.
Other advantages of hypoxic ventilation:
Electro Magnetic Pulses (EMP) is a threat to data systems and data centers in general.
Solar flares or solar storms produce radiation across the electromagnetic spectrum at all wavelengths and may in extreme cases cause problems for computer equipment.
Also volcanic eruptions / volcanic activities may cause energy rich EMP activity that potentially could can disrupt or destroy electronic equipment.
The best protection for such EMP activity is locations underground. Recommendations are to have a minimum 5 m earth coverage to absorb the energy. The server rooms has a coverage of 100 m of granite so Green Mountain is well protected against EMP energy. The location was originally built by NATO to withstand a nuclear bomb. The main characteristics of the site are maintained in the rebuilding process into a data centre.
DC1-Stavanger has redundant fibre paths into the site (last mile).
