InfoBunker
By Drew Robb - Tech Page One Aug 26 2014
Every evil genius deserves his own subterranean bunker with a
supercomputer to plot world domination. The economy being the way it is
these days, however, most can’t afford to build their own lair.
Fortunately, there are plenty of underground facilities that you can
share with other businesses and organizations. There is a coolness about
these locations, and not just because the ground temperature is in the
50s year round.
“There is a certain James Bond allure to the underground data
center,” said John Clune, president of Cavern Technologies. “Many of our
customers utilize the location in their marketing to show how seriously
they take data storage and protection.”

Here are four companies in the U.S. and Europe that are running underground data centers.
Unorthodox location
London-based
TelecityGroup
operates five data centers in Helsinki, Finland. One of them is located
in a former bomb shelter 100 feet below the 150-year-old Eastern
Orthodox Uspenski Cathedral. By using sea water and a heat exchanger, it
uses 80 percent less energy for
cooling
than a typical data center. But not all the heat is sent to the sea.
The water first circulates to a heat exchanger serving the city’s
district heating system, with the servers providing enough heat for 500
homes. The data center won an Uptime Institute Green Enterprise IT award
in 2010.
Data mining
Cavern Technologies
built a 50-megawatt, 300,000-plus square-foot data center in a former
limestone mine near Lenexa, Kansas. Being 125 feet underground means
that the site is secure from the tornados, ice storms and hail that can
hit above-ground data centers in the region.
“From day one, we have a hardened F5 tornado-proof [261 to 318 miles
per hour] structure,” said Clune. “Above ground, it costs up to $150 per
square-foot for a hardened shell. On a 100,000-square-foot building,
that is a cost savings of $15 million that we can pass on to our
customers.”
Secure storage
The Green Mountain Data Center
is a Tier III+ facility located in a former NATO ammunition storage
facility on an island in western Norway. Three-hundred-foot-long tunnels
connect the data center rooms to the outside world. Although the site
is physically remote, high-speed connections mean it is only 4.5
milliseconds from Aberdeen, Scotland and 6.5 milliseconds from London.
One of the main advantages of the site is its energy efficiency.
Located on the shoreline, it draws 46- degrees -Fahrenheit water from a
fjord, an arrangement that allows a 200-kilowatt pump to produce 26,000
kilowatts of cooling. The system is designed for high-density computing,
up to 60 kilowatts per rack. Since it is deep underground, the cooling
system never has to offset heating caused by the sun striking the walls
and roof. In addition, Norway has abundant hydropower, so the data
center operates without greenhouse gas emissions and the power costs
about 40 percent less than it does in London.
“We wanted to build the
greenest data center
in the world and being underground helped in so many ways,” said
Jonathan Evans, Green Mountain’s international accounts director.
Cold War bunker
When
InfoBunker
went looking for an ultra-secure location for a high-availability data
center, it wound up taking over a building that was already designed for
high-tech applications: a former military communications center near
Des Moines, Iowa, that was built to survive a direct nuclear hit.
“From a functionality standpoint the building is performing exactly
the same services it did while under military control, only now geared
towards the private sector,” said Jeff Daniels, InfoBunker’s executive
vice president. “From a cost perspective it was also far less expensive
than a greenfield data center project as we could make use of almost all
the existing base infrastructure and our [capital expenditure] was
limited to upgrading/modernizing systems and building the actual data
floor into what was essentially white-box space.”
Although at just 25 feet deep it is much closer to the surface than
some of the other underground data centers, the amount of steel and
concrete used gives it strength. Daniels said that to replace the
building today, with all its hardening and critical systems would have
cost over $100 million. But it did also require additional work to drill
holes for pipes and conduits.
“The floor is two foot thickness of 6,000 PSI-rated concrete and has
steel reinforcing bars the size of your wrist all through it,” said
Daniels. “It eats core drill bits like popcorn.”
The facility is designed for 10 kilowatts per rack and uses outside
air-cooling nine months of the year, using the heated air to warm the
offices. The building stays at about 55 degrees Fahrenheit year-round
and can act as a buffer to absorb some of the heat if the HVAC goes
down. Waste heat from the servers is used to keep the office spaces
comfortable.
Zombie apocalypse
Data centers such as these are even being touted as a place where people could potentially survive a “zombie apocalypse.”
“Despite advertising ourselves as a 20-megaton nuclear-hardened data
center we do not anticipate ever being nuked,” said Daniels. “InfoBunker
was however nominated one of the top six ‘zombie-proof’ green data
centers worldwide.”
