You've got to hand it to the folks Swedish ISP Bahnhof. They've got style. A few months back we wrote about their Pionen data center. Nestled in a former nuclear bunker just south of Stockholm, it has plants, cool glass conference rooms and waterfalls, inspired by science-fiction classics such as Silent Running. Now they've started construction on a futuristic modular data center, designed by a Bahnhof sister company called MDC Stockholm. The idea is to take tank-quality steel and build out special data-center containers that can be quickly added stacked and linked using an inflatable command module. The module is built by Lindstrand Technologies — the same company that built the parachute used by the ill-fated Beagle 2 Mars mission. "It's very expensive to build a data center, and you always always end up with a lot of empty space before you have any clients," says Jon Karlung, Bahnhof's CEO. With a modular data center, you can expand as you need more space rather than building out a massive complex and waiting to fill your capacity. He says that his designers again took a few pages from sci-fi classics such as Space 1999 and Star Trek. Above: A vision of the Bahnhof containers being flown around in the future.

A fully completed Bahnhof modular data center will house 12 modules, including a power module and a cooling module. These are the same size as the standard 40-foot containers you see being hauled on ships, trains and trucks, but Karlung says that on the inside, they're configured to hold more servers. Bahnoff envisioned these modular data centers a few years back and, after some delays, is finally getting around to building the first one. Image: MDC Stockholm.

The 800-pound doors inside Bahnhof's modular data center use a pneumatic system to open and shut. That isn't just easier on the humans who have to use them; it also saves space. But most importantly, it allows the doors a satisfying pneumatic ssssswish sound when they are used. That's very Space: 1999. Photo: Bahnhof/Roger Schederin
