Green buildings, Green Server Farms?
mstansberry writes "Has IT evolved to the point where it can consider energy efficiency without sacrificing uptime or performance? According to an interview with APC's Richard Sawyer, the answer is yes. The green buildings movement, spearheaded by the USGBC and other organizations has some people thinking about computing infrastructure's impact on the environment. Is it an IT issue or something from C-level executives?"

Considering my mac mini takes less power than just my AMD cpu, let alone not talking about the video card, etc... Im really wondering if the push for massive cpu power at the cost of extreme electrical usage is really worth it.
Green everything should be a good thing, but what if the cost of green than reclamation and regeneration?
Even without environmental questions. CPUs have been getting faster and faster per dollar you spend on them, but they haven not been getting faster the same way per _watt_ you put into them. And each watt put into them also costs power to cool them.
This applies even in the home. Here in California, land of the 14 cent kwh, a 100 watt PC running 24/7 costs $120 per year in power. In a 3 year life the power is more expensive than the CPU or any other major component except perhaps the monitor, sometimes more expensive than the whole PC.
This also plays big on ideas like getting an old computer and putting linux on it to act as a router or music player or other special functions. You are much better off buying a dedicated box like a WRT54G than making use of the "free" old hardware.
And yes, this does have environmental issues, but you can see the problem right away just by looking at costs.
Has it been over a year since you last donated to the Electronic Frontier Foundation
Make enormous energy savings simply by consolidating services...
Stop buying new servers and extend the lifetime of older ones. (Account for the energy costs of manufacture as well as running costs.)
you had me at #!
"Interview?" More like, "opportunity to mention APC's UPS efficiency and then yack about how important that is."
Somewhere, APC's PR firm is quite pleased.
Please help metamoderate.
We wrote about the environmental benefits of virtualization on our site a while back. I even started a little thread on Nanog about any numbers on relationship of server utilization and the energy cost, but it looked like few people cared. To see how underutilized your Linux server is, do:
# cat /proc/uptime
1122029.25 1101982.75
The first number is the system uptime in seconds, the second is the number of seconds it's been idle. The number above is from my laptop - 98% idle.
Virtualization is also going to be the way hardware vendors will keep the server price up - suddenly very powerful servers will start making sense. The questions is - who will win - Xen, UML or Linux VServer. We're banking on VServer. :-)
I want a low power/low heat computer because I want to be able to leave it on all the time. Every PC I've had has been both a computer and a space heater. It is hot enough. I want a computer without the space heater. It isn't that I care so much about global warming. I care about the warming in my own house and all the wasted electricity I have to pay for (both in the PC and my extra AC use). The problem is that it is hard to find a low heat PC. I would like to take the motherboard I have out of the case and drop in a low-heat one. But, all I can find are extremely overpriced complete systems with the obligatory Windows pre-install.
The previous comment is purposely vague and generalized, but all of the facts are completely true.

Q.
Umm... this is only with MS products. Most OSS software can be complied and ran on a 486. MS however adds a lot of overhead on top of what a server needs. A standard web server that is current would require at least 500MHz processor with 256Mb RAM and almost 2Gb of HDD space, (if memory recalls correctly.) Installing the newest debian, BSD, Gentoo or Slack without X, (since this is optional on these systems and a requirment for Windows,) could run on a 486, 32Mb RAM, (more is better,) and about 300Mb of HDD space.
Of course you can install an older version of Windows to save on hardware requirements but you end up sacrificing security updates. Why do that?

Ah! but what color are these chemicals?
air and light and time and space
1) Seasonic S12 series high-efficiency power supply. It makes a VERY noticible difference.
2) Athlon 64 CPU (preferably the new Venice or San Diego core) and Socket 939 motherboard. Enable PowerNOW! power management (current Linux distros like FC3 support it automagically, some BIOSes don't enable it by default). The CPU runs at 800MHz at 1.1V core while idle, jumping to full speed as needed (just like a notebook). Even at full speed power consumption is about half that of an Intel P4 blast furnace. Run 64-bit Linux and get even more work done per watt.
3) Avoid high-wattage video cards like the GeForce 6800 series in favor of 6600GT's. MASSIVE power consumption difference. Depending on how hard-core a gamer you are, the 6600GT's are good enough and a lot cheaper.
See Newegg, etc for the parts.
Because they are already there. In fact I'd say 90% of all web sites out there are already running on less than the power of a 486 today. All 3 of my extremely low-volume web sites, for example, are not even running on real hardware. They are all virtually hosted along with hundreds of other sites on a single high power box. Web hosting companies operate on such a slim margin these days that they are the first to take advantage of any technology that saves energy.
STFU about slashdot bias.
Use a laptop then. The conversion is done on the power strip. Take out the battery and just run off your custom solar power supply then no lossy conversion and you don't have to alter a power supply.
You must be out of touch if you think the vast majority of people use that much power all the time.
PSU Needs Calculator
Using this calculator, a sample system I just made up only needed 319 watts of peak power. To get that, I needed to be running the 3gig barton chip, 2 sticks of ram, 2 hard drives, a Radeon X800, sound, NIC, with 3 fans fullblast and 2 cathode tubes, and a dvd player. Keep in mind that's PEAK power required, which means all of that has to be going top speed to get there, which means something along the lines of running 3D mark while copying a dvd from one drive to the other while playing sound while downloading a file over the internet while having all your fans and lights cranked up.
Hate to break it to you, bud, but just cause you have it doesn't mean you are using it.
Never confuse volume with power.
