Former NATO Nuclear Bunker Now an 'Airless' Unmanned Data Center

Posted by timothy on Thursday January 29, 2015 @05:33AM from the no-humans-involved dept.

An anonymous reader writes A German company has converted a 1960s nuclear bunker 100 miles from network hub Frankfurt into a state-of-the-art underground data center with very few operators and very little oxygen. IT Vision Technology (ITVT) CEO Jochen Klipfel says: 'We developed a solution that reduces the oxygen content in the air, so that even matches go outIt took us two years'. ITVT have the European Air Force among its customers, so security is an even higher priority than in the average DC build; the refurbished bunker has walls 11 feet thick and the central complex is buried twenty feet under the earth.

  The primary purpose of the low-oxygen environment is fire suppression - remember the fire triangle? Underground, a fire is a serious hazard because it's difficult to fight and can spread quite quickly.
  So during normal operations, the servers are in a low oxygen atmosphere which means fire opportunities are minimized. During maintenance periods, it's possible to either use an SCBA (perhaps for emergency service) or to bring in fresh air so people can work normally (because SCBAs are a huge PITA to deal with - all the extra training, potential issues and even just plain comfort - you feel like you're working hard to get air, feel like your suffocating, and the mask can get clammy in a few minutes of use which just makes you want to rip it off).

  My cynical suspicion is that have a datacenter in an underground oxygen-purged bunker is something you cost-justify under 'disaster recovery' or similar; but actually do because of a vague, gnawing, ill-defined dissatisfaction with the fact that your life is basically as safe as it is tedious. The same sort of thing as why really boring federal agencies build huge SCIFs and random suburbanites lovingly shop for tacticool accessories to cram onto their AR-15.
  
  That aside, I assume that they got it for peanuts compared to the original build cost, since abandoned bunkers aren't terribly high-value real estate(and potentially turn into blighted little holes if you don't keep them locked and have a cop watch the entrance moderately closely), and a cold war bunker is probably nice and sturdy, trivial to provide physical security for, and not too much more inconvenient than a situation where equipment has to be taken upstairs by cargo elevator. The oxygen purge seems harder to justify except for the cool factor, though.

  I suspect the battery stacks, generator fuel, or high current wiring for delivering electricity would be some points of greatest risk.
  Theft is not that common in above ground datacenters, either; the facilities are serious about physical security. It is probably due to the same reason the facility is underground in the first place and why people would like to colocate something underground --- higher security, lower risk tolerance compared to applications for traditional datacenters.
  Protection against fire is just another physical security issue being addressed. Without the low-O2.... the risk of damage to equipment by fire would be perceived to be higher in an underground facility with closed and confined spaces than an aboveground facility; less freedom of air to move = potentially greater risk over time of wearing out electrical systems that malfunction and overheat at risk of causing a flame to ignite.
  Also, being underground, there would be no easy firefighter access.

  This may or may not be a serious problem, depending on how they designed the data center.
  Because it is heavier than air (REALLY heavier than air-- you can float a tinfoil boat on it!), all you need to do to evacuate it is add pressurized normal air above it, and have an openable floor drain reservoir to allow the displaced sulfur hexafluoride to exit through. The normal air will displace the gas.
  Additionally, the heaviness of the gas will cause it to stay pooled in the datacenter, meaning you wont have to keep adding gas to the datacenter as often to maintain the low O2 environment.
  Additionally, it is "safe" to breathe sulfur hexafluoride. (About as safe as huffing helium)-- it just displaces the oxygen. it does not itself cause any choking or inhalation hazard other than asphyxiation from low O2. It makes your voice very deep sounding.
  If done right, "draining" the gas could be an extremely cost effective solution. (When done, open the vents at the top of the datacenter, then just pump the gas back into the room from the reservoir under the floor.)
  So, it being heavier than air may or may not be a problem, depending on how they designed the system.

  On the other hand, a halon purge in an underground air tight data center might be very difficult to air out, so they just turned it into a selling point "we never need to air it out, it's always fire proof!"

  Unlike CO2, Methane, Water vapor, and several others, Sulfur hexafluoride is SIGNIFICANTLY heavier than normal air. Inside an enclosed space, where it wont be diluted through mechanical agitation (wind), it will happily remain pooled.
  You know, places like this underground data center.
  The reason it has such a high rating is because it is a fully inert fluoride complex. The energy needed to break it down is crazy high. That's kinda important here, because it's used for fire suppression and electrical spark suppression. Normal UV exposure in the atmosphere is enough to break down methane, and plants break down CO2. Weather temperature equilibrium keeps water vapor under control. Something like S-F6 would stay in the atmosphere a VERY VERY long time if just irrationally released.

Hypoxic air technology for fire prevention
Hypoxic air technology for fire prevention, also known as oxygen reduction system, is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms. Unlike traditional fire suppression systems that usually extinguish fire after it is detected, hypoxic air is able to prevent fire.
Design and operation
Air with a reduced oxygen content is injected to the protected volumes to lower the oxygen concentration until the desired oxygen concentration is reached.
Air with low oxygen concentration is produced by hypoxic air generators, also known as air splitting units.
Effects on health
Fire-prevention systems which result in the oxygen content being less than 19.5% are not permitted for occupied spaces by federal regulation (OSHA) in the United States [3].
However, hypoxic air is considered by some to be safe to breathe for most people.[6] Medical studies have been undertaken on this topic. Angerer and Novak's conclusion is that "working environments with low oxygen concentrations to a minimum of 13% and normal barometric pressure do not impose a health hazard, provided that precautions are observed, comprising medical examinations and limitation of exposure time".[7] Küpper et al.[8] say that oxygen concentration between 17.0-14.8% does not cause any risk for healthy people by hypoxia. It also does not cause risks for people with chronic diseases of moderate severity.

Matches go out at around 13% oxygen by beastofburdon · 2015-01-30 07:33 · Score: 1

A match will go out quickly at 13% O2. A human can survive in this environment, albeit with a headache and very lethargic. I know, I spent two months on a submarine with the O2 hovering between 13%-15%. By the way, no matter how much sleep you get under these conditions you still feel like you haven't slept for days.
Sulfur hexafluoride problems by Anonymous Coward · 2015-01-30 08:41 · Score: 0

Sulphur hexafluoride is not an inert gas. The problem with SF6 is that any vigorous activity like electrical sparking or fire will cause it to decompose into very toxic byproducts like HF (hydrogen fluoride) and SF4 (sulphur tetrafluoride).
