The 100 Degree Data Center
miller60 writes "Are you ready for the 100-degree data center? Rackable Systems has introduced a new enclosure that it says can run high-density racks safely in environments as hot as 104 degrees (40 degrees C), offering customers the option of saving energy in their data center. Most data centers operate in a range between 68 and 74 degrees. Raising the thermostat can lower the power bill, allowing data centers to use less power for cooling. But higher temperatures can be less forgiving in the event of a cooling failure, and not likely to be welcomed by employees working in the data center."
Its better
I'd be mostly concerned about the lifespan of hard drives at these temperatures. The electronics can be easily made to tolerate heat, but drives are a weak link. The bearings and lubricants are especially vulnerable.
I realize it's the trendy thing these days to target the data center as an area of concern monetarily, but this is a little ridiculous.
All it will take is one poor geek spending a 12 hour day in the data center for this to be deemed a horrible idea. (Like that never happens)
Seriously, this is retarded. If you do your cooling and power CORRECTLY, you won't have a ridiculous bill and your data center will be at a more reasonable temperature.
I hate really hot weather...you can always put on more clothes, but you reach a limit on what you can take off.

Not welcome? That all depends, on if I can relocate my Data Center to a topless beach in Miami. Sure beats the current scenery, and the dress code would likely change.
Of course, the fact that you probably don't want to see your average IT person running around topless wearing a thong is another matter entirely...
Buildings provide hot water for washing hands etc. Cold water comes in from outside and is heated using electricity or gas to make hot water which costs money and energy.
Pipe the cold water (which is usually somewhere between 0 and 20 degrees C) through heat exchangers in the hot data centre before heating it up to working temperature with gas or electricity.
That way, you reduce the data centre's temperature to more like 20-25C, and you heat the water up by 10C (say) saving on gas or electricity bills since there is less of a temperature difference to get it up to the required temperature.

Yes there saving money on cooling cost, or at least they seem to believe that and I am sure when they fail to take everything into account this is true.
The reality it the server room still has to pull that heat out. Increased Delta T is just lost energy.
Here is really why it's a terrible idea.
1.) Component failures. Of all parts from bearing in the drives, and fans to the silicon itself has a much higher failure rate.
2.) The components use more power at higher temperatures! This is from increased leakage currents in the silicon.
Below is a graph from Research My Startup company did!

They really need to used ducted air or any other technology to reduce the Delta T! By this I mean bring the cooling as close to the components as possible.
Right now server rooms need to run internally at 10C to 15C to keep the CPU chips below 60C.
If they just brought the cooling directly to the cpu's and let that cool spread from there they could use out door passive radiators! 0 air conditioning cost and the most power savings.
This is what my start was doing till someone tried to steal the who damb thing and sunk the company.

373.15 - Water boils at 1 atmosphere 310 - Very hot 300 - Hot 290 - Nice 280 - Chilly 273.15 - Water freezes at 1 atmosphere 0 - absolute zero! how easy is that.
'xactly. These trolls try to go anti-US with their fancy metric system then they fuck it up with Centigrade. Try plugging centigrade temperatures into the ideal gas law and lemme know how it goes. ;)
A single degree Celsius is qualitatively a bit too big, to the point where most European climate-control systems with digital displays have to resort to using half-degrees as the base control unit.
