How-To: Earn Your Carbon Credits

The past few years have showed us a boom in the fad of "going green" with everything from automobiles to your home. Some people have taken advantage of the situation and claimed the need to put a price on the amount of carbon emissions each individual puts in the air. Everyone should be given a quota and if you go over that quota you need to buy "carbon credits" otherwise you face "penalties." I'm glad we haven't reached la-la land just yet, but there are simple ways to go green without going overboard.

I run a server at home for routing, web, email, files, and almost any little idea I think of. Now that I've told you I will have to kill you as ISPs frown on this freedom of expression. Anyway, this server has been comprised of spare parts and/or whatever I could buy for $20. Now that I have a decent job, I decided I wanted a computer I could call a server and stand by it. It also had to draw less electricity and put out less heat and noise. Let's compare my setups:

Junker
  • 1.4ghz "Tualatin" Pentium III-S
  • 512mb PC-133 RAM (i815 chipset limitation)
  • ASUS TUSL2 motherboard
  • 320gb Seagate 7200.10
  • Intel 100 mbit and 1000 mbit PCI cards
  • $50 case with 350watt PSU (all-in-one)

Upgrade
  • 1.86ghz "Lynnfield" Xeon L3426
  • 4gb DDR3 1333 ECC RAM
  • Supermicro X8SIL-F motherboard
  • 2x1TB Seagate 7200.12 (RAID 1)
  • Dual on-board Intel 1gb NICs
  • Antec MicroATX case + SeaSonic 500watt 80 Plus Bronze PSU

The junker runs at a nice loud, slow pace. PHP and any disk intensive request was a several second ordeal. Most of that is due to the limited amount of RAM. I hooked up the Kill-a-watt power meter to the junker to see how much electricity I'm wasting. 62 watts - at idle. The computer is lifeless and it's eating enough energy to power an old school light bulb. Think of all the nuclear power I'm wasting; I can't sleep at night.

Putting the new server together was the fastest assembly for me yet. Most things are now on-board and the only power connections were for the motherboard and hard drives. Hitting the power switch brought forth... silence. Ah... What's this? A BIOS prompt. After installing Fedora 11 x86_64 using my USB drive (no CDs or floppies were hurt in this process, something other OSes can't say), I ran the power meter on it. A whole... 40 watts at idle. With more than 10 times the computing power (and 1 vs 4 cores) and an additional hard drive, the new system was eating 22 (woot math) less watts! Just to put this in an even more interesting twist, my one year old desktop computer pulls a hefty 96 watts out of the Earth. It has a 9800 GTX+ helping it get that high though.

What's the meaning of all this? Well, I should get some nice medal from Al Gore for saving the planet, right? Heck, I'd take just a letter. Now get out there and green up your computing environment. Doctor's orders.

Ancient Computers Recycled


Usually I have a piece of computer hardware that I must have, but usually I don't get it right away. I wait until it's marked down from MSRP. Sometimes that wait is five years long. In that case, I upgraded my main server from a 1.13ghz Tualatin to a 1.4ghz, which was the fastest made. This process required me to also upgrade the motherboard since all but a few supported anything beyond a 1.2ghz Tualatin. Why would I do this? First off, the entire upgrade cost me $40 without shipping. Secondly, I was always facinated by the Tualatin CPU line, as nerdy as that might sound. So after having to dust off my floppy drive in the closet (because I also had to upgrade the motherboard BIOS), I finally got the computer upgraded. Then I tried booting without a keyboard. While the Intel motherboard I had previously booted without a problem, this ASUS motherboard will not. "Keyboard error. Keyboard not found. Press F1 to continue." *sigh*
