Iceland Woos Data Centers As Power Costs Soar 142

Posted by kdawson from the where-cool-meets-hot dept.
call-me-kenneth writes "Business Week covers the soaring demand for power and cooling capacity in data centers. Electricity consumption for US data centers more than doubled between 2000 and 2006. Among the other stats: for every dollar spent on computing equipment in data centers, an additional half dollar is spent each year to power and cool them; and half the electricity used goes for cooling. Iceland, with its cool climate and abundant cheap power, is courting big users like Google and Microsoft as a future data center location. (Can't help thinking they're gonna need a bigger cable first, though.)"

      There's a more useful map in the article itself [invest.is], and the text gives the capacities of the lines:

      Farice is running at 20 Gb/sec capacity with an ultimate transmission capacity of 720 Gigabit/second and CANTAT 3, which has 5 Gb/sec capacity both ways with an extra 2.5 Gb/sec to spare.
      • Data centre of the world? Well maybe not right away, but they have the ability to increase there bandwidth by 700Gb/s which should be enough for a few large companies datacentres I would imagine. Plus building large datacentres would take a year or two during which time new lines could be run. Iceland should be a big winner, less cooling needs as the average annual temperature is around 5C (you might actually want the heat :), the energy is clean, and they are equidistant to both Europe and North America.

          I certainly don't think heat pollution will be a concern. Gigawatt size coal plants and nuclear reactors have to worry about heating nearby rivers, but in this case we are talking about the additional load to run datacenters heating the Atlantic Ocean. A 1 GW electric power plant will typically reject 2 GW thermally (which is a lot of local heat). But 3 GW is a lot of power to be generated in one spot. The renewable energy sources of Iceland certainly don't generate anywhere near that much power per unit area. And the heat rejected from datacenters will be trivial and widely distributed.

          I think two things will stop these datacenters from going to Iceland: restrictive immigration laws and submarine data cable capacity. Iceland has a total population of about 300,000. They simply can't have a diverse enough IT industry to support setting up these data centers without expats. And without the bandwidth, there simply isn't a point.
          • I think you might be surprised by the pull Google would have. A data-center of google magnitude means a lot of revenue + IT benefits + any immigrants will be well educated. The bandwidth however is a problem, I think they should put it in Scandinavia personally. Though I don't know how much more expensive electricity could be there. Atleast they have a land connection, plenty of icy water and easy to deal with governments.

        No, they aren't, at least not as a general rule. The general rule is that all children are "named" after their father (and I'm putting that in quotes since it's not really a name as much as a *description* of who you are); it's possible to use the mother's name instead of the father's, too, but it's neither restricted to nor standard for either sex.

    I would suggest locating data centers in a cool climate where farming is popular. Pump the waste heat from the data centers into greenhouses that can surround the data center. Now that waste is helping to grow food.

    Alaska is actually a good place to implement such a solution. There is a huge amount of sunlight in the summer which, assuming you can avoid frosts, can grow amazing produce. All you need are greenhouses and a heat source. In the winter, when sunlight is no longer plentiful and farming shuts down, the heat can be pumped into local housing. Such a solution would also provide local produce in Alaska - produce that is fresh and doesn't require expensive shipping. One last point about Alaska, it's very central. It might not appear to be when looking at a map, but if you look at a globe you will see that it sits nicely between Asia and North America.

      Unfortunately, here in Alaska, we're undergoing an energy crisis. Here in Fairbanks, where I live, most electricity is supplied by coal and fuel oil. Due to the massive spike in oil prices, energy costs have risen greatly. In southern Alaska, most electricity is being supplied by natural gas, but even that's getting more expensive as the southcentral gas fields begin to run low. Though the short term is somewhat difficult, there is hope from a projected series of natural gas pipelines from the North Slope and the potential for dozens of hydroelectric and/or nuclear plants. Until then, however, electricity prices put the kibosh on most big server farms up here.

Double this for inefficient cooling and power conversion in the UPS (this is overly costly but makes up for underestimating power usage) so 500W. There are 8,760 hours in a year so 4,380 KwH, you'd have to pay $.20 per KwH to reach their figure, this is over twice the US national average. Prices where you'd want to put a datacenter are closer to $.06-$.08 per KwH. My average server cost closer to $7,000 with battery backed RAID card, dual fast drives, dual CPU's, 4GB memory, 3 year 6 hour repair contract, etc. Even powering that kind of servers off diesel generators fulltime it would have to draw ridiculous amounts of power to cost half it's purchase price in electricity every year.

    Air heat transfer is not that good, and you can't just pipe in outside air to cool the data center (due to dust and humidity control), so it doesn't generally work out that a cool outside climate lowers cooling costs significantly. If you compared it to some place with high (35C) normal temperatures, it might make enough of a difference (because standard air conditioning efficiency does drop off in that range IIRC), but that is not most of the US. Also, 50% of power going to cooling is not representative; it should be down closer to 35% from what I remember of our numbers (and we're in a location with relatively hot summers). Our electric rates are also already pretty cheap; commercial rates can go as low as 4.721 cents per kilowatt hour (plus a demand charge).

      I would think that filtering cool/cold air and processing it for removing the humidity would still cost much less than actually colling to lower temperature hot air. If the air is too cold like Canadian winters, you will actually recycle the air within the data center and just heat up a bit the small incoming air from the outside to get ride of the humidity.

      But I am not an expert in the field. Numbers would need to be crunched to see how effective that is.

        All air conditioning has filters to remove the crap in it. However if you look at the max air inlet temperatures quoted by manufactures there are plenty of places in the UK that could provide it from outside air 365 days a year, as the maximum recorded historical temperature (over a couple hundred years) is below that of the max air inlet temperature.

        A quick search shows that the maximum recorded air temperature in Reykjavik is just under 25 Celsius, so no air conditioning need even on the hottest of days.

      If the air is cold enough, then there won't be any humidity, and dust is relatively easy to filter out.
      The colder air outside will render the external condenser of the aircon system more efficient, remember all aircon does is move the heat around. And you could use some level of heat exchange too, pump the warm air through a series of heatsink-clad pipes located outside and it will cool down fairly quickly.

        While I am no HVAC engineer, I pretend to be one on odd-numbered days.

        Cold climates have several real challenges for data centers. From an HVAC standpoint, there are two general ways to cool a data center in a cold climate-- outside air only and air/water cooling. Air/water systems have drycoolers with glycol kept around 30-40F, and circulate the cold water throughout the building to fan coil units. Minimal outside air is brought in for "fresh air," and must be humidified which generally requires a lot of energy.

        The air-only systems bring in 100% outside air, but must first temper (heat-- to avoid condensation) it and increase the humidity to control static inside the space. Very little pump energy, but the humidification and pre-heat are expensive.

        While it seems trivial to filter out dust, the better air filtration systems increase the pressure drop of the air handling unit, and force you to use a bigger fan. Heat wheels and enthalpy wheels are also an option, but have similar challenges in most real-world situations.

        The biggest challenge with cold climates is making sure the diesel generators start when needed. This alone makes most data center managers skeptical at the prospects of cold-climate data centers.

        For a truly efficient solution, the best approach is likely to be heat removal at the chip level and recovery for other purposes. 100F air isn't very useful, but if you can get 150F water off the chip then that heat can often be reclaimed for some other purpose more effectively. If all else fails, 150F water is pretty easy to cool off in a closed circuit dry cooler no matter what the outside temperature.

        There is also a lot of work going into direct-evaporative cooling solutions (swamp coolers) for data centers, as well as some other non-compressor based cooling systems. Unfortunately, most of these can work very efficiently for 9-10 months a year, and need a separate system to cool for the remainder of the year. Having two systems makes the payback equation often favor the less efficient solution...

          No, truly efficient solution IMHO would be lower powered/more energy efficient devices. We all know that these are most likely Intel systems and in the race to add gates and mHz, efficiency got left by the sidelines.

    Many of the comments are focusing on the outside temperature in Iceland and linking that to decreased cost of cooling. That may be relevant, but it's not the point. The point is that power is cheap and plentiful here (mostly hydro, some geothermal).
