Region Zealand is centralising its computer operations and using nature's own elements to cool down the computers' nerve centre: the server room.
T
he room is bathed in a cool blue light. Ringsted Hospital now has its own CPU centre: the new IT operations centre functions as a central junction for computers right across Region Zealand. By placing the region's servers under one roof and cooling them with air from outside, Region Zealand saves both electricity and CO2 emissions. the ComputeR CooleR "Mother Nature has a hand in our efforts to contribute to a higher purpose. That kind of thing helps our motivation a lot," says Michael Hansen, head of IT at Region Zealand. Passive air cooling saves Region Zealand more than EUR 135,000 on its annual electricity bill. "It makes sound economic sense to think of the environment, and that makes the decision very simple," Michael Hansen continues. Passive air cooling exploits the fact that in Denmark, the air outside is so cold for much of the year that it can partly or wholly replace powered cooling compressors. The cold air
from outside is transferred to the server rooms using heat exchangers. "A well-designed passive air cooling system for a computer centre can reduce its annual electricity consumption by about 70 percent," says Niels Henrik Harbo, project manager with COWI, which designed the system. Joining up the patChWoRk Setting up the new centre involved the delicate task of moving sensitive equipment. All of the IT systems, hardware and software had to be collected from the three former counties, and brought together in Region Zealand's new centralised IT operations centre. "We started out with a patchwork of unconnected systems. Today, we have joined it all up in an energy-saving pentagram," says Michael Hansen. Most of the system's 15,000 users are based at the region's hospitals, so they rely on stable computer operations. The 300 servers which have already been moved have mainly come from the town of Nykøbing Falster.
