Re: Low-power PC
A new chapter added to this never ending quest for lower power usage
I built a new Intel i3 based server because some of my hardware is acting a bit strange lately.
The power usage reduction of >50% is getting me into the sub-30W range, but still with lots of processing power.
I think I can lower power usage even more, but I'm waiting for some parts to arrive...

Re: Low-power PC
Robert, nice setup. I am curious how much difference it makes when you pull half of the memory out. I found that memory is effecting usages a lot now other parts are more efficient.
Can you alos make a overview of the total costs?

Re: Low-power PC
Nice work Robert.
My next step for a HA servers is make a move to a tablet
like yourtablet 2000 Atom 455, 32GB SSD
This depends on the usage. My hope is that the usage will be dropped below 6 watt
I'm going to use this for
Homeseer
Plugwise
Irtrans
Itunes
HSTouch

Re: Low-power PC
@Bastiaan: Total costs incl. PicoPSU is around 950 Euro; 50% of the costs are the 2 SSD's.
@Alexander: Thanks, I read (small parts) of that thread last week, really impressive! For me personally this goes a bit too far; with all this teaking I wouldn't have time for anything else anymore I guess

Re: Low-power PC
Enver,
When there's a tablet on which I can run multiple (at least 5) VMs, with 2 NICs, >200GB local storage, I will consider it
We'll explore the possibilities for that again in 3 years or so

Re: Low-power PC
no change for vm on a tablet at the moment..maybe in few years..
i3 is the best solution

Re: Low-power PC
This is my new domotiga live/development server, small physical size.
Power usage is between 25-27 watt, without any bios tweaks or other optimizations, measured with plugwise plug.
I think the ECS board has less power saving features than the MSI's have.
It replaces my Asus eeebox which uses 18-20 watt, but was getting a bit slow with latest Ubuntu Maverick, it also had only 1GB of memory.
The Asus scored around 5500 BogoMIPS total.
Code: Select all
Intel i3 540 CPU @ 3.06 GHz
ECS H55H-I mITX motherboard
8GB RAM (2 x KVR1066D3N7/4G)
OCZ Vertex2 60GB SSD
PicoPSU 80 Watt
Chieftec BT-02B MiniTower, mITX
Running Ubuntu Maverick 64 Bits.
I think the ECS board has less power saving features than the MSI's have.
Code: Select all
CPU0: Intel(R) Core(TM) i3 CPU 540 @ 3.07GHz stepping 05
Booting Node 0, Processors #1 #2 #3
Brought up 4 CPUs
Total of 4 processors activated (24469.72 BogoMIPS).
The Asus scored around 5500 BogoMIPS total.

Lol, just read what he did, look at the hardware-mods list on this linked page, I think my soldering skills are above average, but this is insane...Alexander wrote:@Robert: Interresting material for you: http://ssj3gohan.tweakblogs.net/blog/60 ... wijs!.html (read other posts)

Re: Low-power PC
With 5 VMs moved to the i3 server it's now consuming 37W. A PicoPSU will arrive some day soon and I still have to disable some things I don't use. Undervolting etc. is not something I want to experiment with on this machine; it's too "important" for that
I think I can reduce it back to around 30W or a bit more.
To be continued...

Re: Low-power PC
Today I replaced the PSU with the PicoPSU, resulting in a power usage that dropped from 37 to 32W.
My goal when I started this was 30-35W, so I'm satisfied with the result.
If I could only get rid of 1 Windows XP VM which consumes a lot of CPU;
The process which consumes the most CPU time in there is the Plugwise Source...
Could probably save me some more Watts!

Re: Low-power PC
Hi,
Just wondering, what is the base OS that you are running. i.e. are you running a Windows system and on top of that Windows/Linux VM's or a Linux system with Windows/Linux on top of that?
And, of course, why is one option preferred over the other?
