Iceland Woos Data Centers As Power Costs Soar 142
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.)"

1) cheap geothermal power
2) cheap geothermal cooling
3) easy freight
4) educated and even DNA-tracked populace
5) computing is an indoor sport
Five considerations:
1) they like to go whaling; not necessarily a friendly thing in by some opinions
2) latency; not as a bad as a sat, but not as good as Chicago for US; geo centric for North America and EU
3) earthquakes and unsettled geography
4) too many thermal pools to screw off in
5) don't want my server called 'homerdottir'

If that's Homer as in Homer Simpson, the server name would be margedottir. In Iceland, the daughters are named after their mothers.
Iceland is probably cool enough that a well designed data center could forgo air-conditioning, unlike the eastern Oregon or eastern Washington sites popular for data centers.

2. Real reason anyone goes to Iceland: Icelandic girls [youtube.com] (fast forward to the third minute)

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.
(Also, to pick some nits, you've misspelt "dóttir" (and don't tell me about English dropping accents - it's a different letter, not an accent), and the father's/mother's name is put into the genitive case. For example, the son/daughter of Anna could be Önnudóttir, not Annadóttir or Annadottir - that is, assuming their patronymic name wouldn't be, well, patronymic (deriving from their father's name), of course.)
Hope that clears it up! :)

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...

Iceland doesn't have much in the way of natural resources but it has all that power. The way to export that power so far has been to import alumina and export aluminum. The conversion takes a lot of energy. Server farms are another way of exporting power.
The problem is that no-one in their right mind would house their servers here. We have no real redundancy in connectivity. One cable breaks and we suffer increased latency and reduced throughput. This happens more often than most data center clients could tolerate. The good news is that this problem can be solved with more cables. They're not cheap, but neither is building aluminum smelters. Once there are at least two cables going west and two going east, each with sufficient capacity to carry the whole load, then Iceland will be a very nice place for servers.
