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

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.

      Technically SCBA like the fire department uses, unless they use rebreathers.

      Or just pumping in normal air.

      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).

      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.

      Of course it is. So is water vapor.

      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. Used properly, it shouldnt escape.

      S-F6 is 6x heavier than normal air.

      Pure nitrogen is not anywhere near that level of disparity. Also, pure nitrogen does not have the same electrical insulation properties. You could put a tesla coil in a S-F6 atmosphere, and it would not discharge until a VERY significant voltage had been achieved.

      This means that even if an electrical failure occurs in the datacenter, sparking would not be a source of secondary ignition.

      Pure nitrogen would also be harder to determine when the atmosphere in the datacenter was safe for human respiration. With the S-F6, if you inhale it, it makes you sound like a steroid pusher. You could immediately tell if the atmosphere had not been vented, long before you became woozy and light headed from O2 deprivation.

    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.
