Sun to Create Underground Japanese Datacenter

Kurtz'sKompund writes with word of a Sun project in Japan, one that's taking a somewhat non-standard approach to data center construction. To save on power, heating, and water costs, the consortium is going to be building their center in an abandoned coal mine. The outpost will be created by lowering Blackbox systems into the ground; estimates on savings run to $9 million annually in electricity alone.

    This could be an interesting use of the Earth's tendency to be a thermal sink. Caves are always about 55 F, as I recall. Maybe they can use this to their advantage.

      The temperature in a cave means nothing, unless you take into account the cave's ability to dissipate heat somewhere (water or air moving through the cave). If you go inside a cave that's been at constant 55F for a thousand years and you suddenly heat it with 50 kilowatts of power from your data center the temperature will settle at 255F in a hurry. About the only advantage you get from a cave is a constant supply of really cold water (if sufficient rain that year). Ambient air temperature is irrelevant since usually you don't have a strong draft in a deep cave and static air will heat up pretty quickly.

      Whoa. Coincidentally, that's the optimum incubation temperature for Mothra larvae.

      For the sake of humanity, let's hope that Sun is factoring this into their cooling calculations.

      Does not the air conditioning cycle in these black boxes also remove humidity ? I worked at Sun and got to play with these containers. They remove the humidity from in coming air and are cooled with water.

      It seems like the idea is to use the mines water to cool the containers and dump it back into the mine to be cooled and reused. They also have dehumidifiers built into the Black box to prevent condensating moisture inside.

      I worked on wiring one with a couple cohorts and even sweating in these things is a joke , it's pretty much sucked up in about 5 minutes of being sediment in the box.

  3. Savings in Electricity... by darthflo · · Score: 2, Informative

    According to TFA, $9M could be saved on electricity when using 30'000 server cores. Also according to TFA, 10'000 cores are planned with a $405M budget. If power demand scales directly with the number of cores, this would equate savings of $3M annually. Based only on these savings (which of course won't be the only factor, but since TFS and TFA single them out so clearly), this project breaks even after a measly 135 years or about five and a half times Sun's current age.

  4. Are they crush proof? by rueger · · Score: 4, Insightful

    The Blackbox containers are robust enough to withstand earthquakes, being capable of withstanding a quake of magnitude 6.7 on the Richter scale.

    I don't know, but placing servers 100m underground in a place that routinely is hit by large earthquakes seems a dubious idea. The containers themselves may survive a quake, but what happens when the disused coal mine collapses onto and around them? Even if the containers and servers survive, will the power and data cables? If the tunnels collapse how will you get to and from the servers for maintenance?

      Two possible outcomes:
      1: Mine collapses, buries everything under millions of tons of rocks and stuff, Blackboxes and cabling survives, Sun market's "the world's most secure datacenter".
      2: Mine collapses, buries everything under millions of tons of rocks and stuff, Blackboxes and/or cabling gets scratched and/or really damaged, Sun hires Godzilla (this is Japan, where Godzilla's big in, remember?) to smash away them rocks and free the mine once again.

    A solar neutrino observatory is installed in an old mine in Sudbury, Ontario, Canads. It has the advantage of being impervious to almost all kinds of radiation, except of course for neutrinos. http://www.sno.phy.queensu.ca/

    Since the computers produce a lot of heat the humidity wouldn't be much of a problem, try putting a computer in a humid garage, the computer will be just about the only thing dry in there.

    I do wonder how much this thing will really save, I wouldn't be so surprised if the costs are comparable to the normal installation (remember, the normal installation costs for these things is near 0, they just need a power, network and water plug). If they'd just put the server somewhere with some other cooling source available (a lake for example?) it would probably be even cheaper.

    You raise an interesting point about heat dissipation in an underground datacenter. I remember seeing something on NORAD years ago about the construction of the command center inside Cheyenne Mountain. One of the things that stuck with me was the fact that there was no dedicated heating system: they merely ducted the waste heat from their 150+ mainframes throughout the entire installation. Kept 'em all nice and toasty warm, even in a Colorado winter.
