    No, it's not the most energy-efficient in the world. The numbers they published were only from a VERY limited timespan during the coldest part of the year when energy needed for cooling would be drastically lowered.

    If they published a full-year figure, I can guarantee you it wouldn't be nearly as good as the published one.

      Agreed. And what about being environmentally friendly? There sure are a lot of filters that would need to be replaced on a regular basis. I know this because I'm a refrigeration/air-conditioner technician. I'd like to learn more about how 'environmentally efficient' they are. Not just energy-efficient.

      • I think this would depend entirely on the materials used for the air filters and the source(s) of electricity used... I don't consider outright disposal, or landfill of paper products harmful to the environment... trees are a renewable resource.
    • You might well be right, but wouldn't that be reason for more environmentally friendly designs be made public. It would cool to see companies out-competing each other over improved environmental designs if data centers.

      BTW Can you point to some existong data centers that are likely to out compete already? I would be curious to see their designs.

        One of the reasons this will probably work well is that Facebook has the advantage of not being in the data centre business per se. They use data centres, sure, but they don't sell them, which means they have nothing to fear from competitors copying their good ideas. Major hosting companies would quite likely be more reluctant to say "here's our great new idea, any ideas on how to improve it?", because they have much more to lose if someone comes along, works out an improvement, and then implements it for themselves rather than passing it back to the community.

        • It's pretty much a classic application of the major business case for "open source" anything(the second, typically less significant, one being to assure a customer or customers that you aren't locking them in, if they are large enough or the business competitive enough, to demand that): commodifying your complements.

            So on top of destroying hardware, most of which is not replaceable under warranty (I doubt Dells 4hr business service accommodates water damage), they are trying to put out electrical fires with water. I think we can assume the majority of fires in a data center will be electrical.

              They are pumping tons of air through the facility. Lowering o2 levels with a nitrogen or a halon system would be pretty ineffective. A chemical bottle extinguisher is pictured in one photo - manually extinguishing local fires (like if an AC panel goes boom) would probably be expected. The sprinkler system is probably code mandated to keep the whole facility from going up in flames in a disaster.

    Several large data center operators are trying to win this "most efficient" title and putting lots of innovation and resources into them. However, you need to be very careful at comparing the outcome. First notice the actual claim, "most efficient". The Facebook data center consumes water to reduce energy needs. This can be a very dangerous practice if followed on a large scale. Consider the recent annex of a US government site in Utah in order to get priority water service. http://www.datacenterknowledge.com/archives/2011/03/09/annexation-boosts-cooling-for-nsa-data-center/

    So far, anyone attempting to lay claim on the "most efficient" title has moved things from the cooling column, sometimes into the computer load column (most notably fans), sometimes over to water consumption. Yes, you get a better efficiency awarded if you consume more power in non cooling areas.

      Water can still be used to for example irrigate crops after it has been used for cooling, you can use non-drinking water such as seawater for cooling, though you might want to keep that a bit further away from the computers than you would for pure water, perhaps as a secondary heat exchange, and there are parts of the world with plenty of water, such as Canada, Scotland and Scandinavia.

        Yeah, Living in Canada, I always laugh when they talk about water conservation. Not that we should waste it, but we have much bigger environmental problems to worry about. If there was anywhere near a shortage, it wouldn't cost only a couple buck for a cubic meter (1000 L). Most of the problems with water in this world are a distribution problem, not a supply problem. And water is something that is quite expensive to transport. It's not like you can dehydrate the water to bring the weight down.

        • I live in Arizona, and still don't get the argument... if you are using well water, or otherwise isolated, sure... but in general water evaporates, becomes clouds and rains/snows back down again... Used for cooling, like in nuclear plants, it isn't tainted, lost or otherwise removed from the planet, just evaporated. Now split for hydrogen use, that's a different story slightly.
          • The problem is the water doesn't necessarily come down in the same place. This means what ever you are taking out the ground is not necessarily being replaced at the same rate. This is even more true when the number if people exploiting it increases. There are plenty of cases where the level of the water table has dropped from over exploitation.

      • by Cramer (69040)

        Not the way they're doing it. Evap cooling vaporizes the water. Once it's vapor, it's hard to drink, irrigate, etc. with it. You'll have to wait for it to condense back into liquid (ala rain, snow, sleet, etc.) before it's "usable" again. As others point out, that's very rarely a closed system -- the rain comes down hundreds of miles away.

        The way many (some?) office buildings are cooled, on the other hand, does not vaporize the water. It takes water from the muni supply, runs it through a coil, and ret

      Depending on how local power is generated, the power consumption column may or may not be hiding a substantial amount of water use as well(the giant cooling towers, billowing clouds of steam that weren't successfully recovered, are not there for show, nor is the siting of many sorts of power plants next to bodies of water just because operators like paying more for picturesque real estate with flood risks.) Some flavors of mining are pretty nasty about using and/or filling with delightsome heavy metals and such, water resources as well.

      I don't mean to detract from your, eminently valid, point that there are a lot of accounting shell games, in addition to actual engineering, going on when being "efficient"; but it is really necessary to decompose all the columns in order to figure out what is hiding under each of the shells(and how nasty each something is).

      Swamp coolers are a great way(in non-humid areas) to reduce A/C costs and increase clean freshwater use. Whether or not that is a better choice than using more energy strongly depends on how your friendly local energy producer is producing. Odds are that they are consuming cooling water(or hydropower's consumption of water with potential energy); but it isn't always clear how much.

      Regardless, though, what you Really, Really, Really want to avoid is situations where archaic, weak, nonsensical, and/or outright corrupt regulatory environments allow people to shove major costs under somebody else's rug. Why do they grow crops in the California desert? Because the 'market price', such as it is, of water sucked from surrounding states is virtually zero. Why are there 20-odd water-bottling operations in Florida, a state barely above sea-level and with minimal water resources? Because the cost of a license to pump alarming amounts(you guys weren't using those everglades for anything, right?) of water is basically zero(unless you are a resident, of course, they face water shortages. Trying incorporating next time, sucker). Similar arguments could be made that energy users in a number of locales are paying absurdly low rates for the Appalachian coal regions being turned into a lunar theme park, among other possibilities.

      Playing around with 'efficiency' numbers is a silly game; but largely harmless PR puffery. Making resource tradeoffs that are sensible simply because they allow you to shove major costs onto other people at no cost to yourself is all kinds of serious.

      I'd wager a good 70% of us could go look at our energy bill right now and see that just wouldn't be possible.

    I have to wonder how much power that would use if it ran on mainframes or large UNIX servers rather than unreliable and relatively slow clusters of small machines. It's strange that none of the "new generation" websites are choosing to go with bigger systems, despite the fact that they tend to perform better on both performance and power/performance.

      I think it's a problem of culture. With "agile" methods they're pushing code all the time and using their distributed infrastructure to test it in real time. So they deploy to 10-20 machines, if it's ok then to 100-200, etc... Having just a few huge optimized servers with broken would affect too many users at once, so I guess web companies are confortable with their commodity server.

        I don't think that's exactly their point.

        The point is more "why spend more money on big-iron if it's going to eventually fail anyway?" If it's going to fail eventually, you'll have to program-around the failure mode, but once you properly program-around system failure why going with the more expensive equiment? Go with the cheaper one and allow it to fail more frequently, since it really doesn't matter now.

        But the thing is, even with big iron you still need to plan for downtimes and maintenance. For the scale of some of the "big" sites out there you still end up having to build software that can tolerate failure. Planned or unplanned. All of the utility of the big iron goes away when you still have to plan to fail over.

      I've done these numbers before. How about this:

      IBM Power 795 (4.0 GHz, 256-core) 1TB ram - specint rate 2006 = 11,200 - $2m
      AMD Opteron 6176 dual socket (2.3Ghz, 24 core) 128GB ram - specint rate 2006 = 400 - $8100

      So you need about 30 AMD machines to get the same speed. That's about $250k including rack and networking. Right off the bat you're talking about a 1/8 the cost of the IBM power system.

      As for performance/watt, the AMD machines need about 600W each. A rack plus switch is probably going to need 2

      A blue LED like the ones used are probably 5-10mW max. A not so bright 5mW LED * 10k machines = 50W used. 50W is probably 0.001% of the power used by a cluster of that size.
