Re: Most energy efficient (home) setup

I've run a SheevaPlug at home for a few years now.  I don't do
anything fancy with it, but it does what I need it to do.  Mostly that
is file server, web server, jump-box for network testing.  Also
testing different linux software for this and that...  (Quagga runs
nicely, but won't hold a full BGP table :)

There are no moving parts in my home computer/networking gear, unless
my laptop is running.  That was the goal for me.  I recently grabbed a
couple of TPLink WR703N devices to mess around with as well, but I
haven't had a chance to dig into that much.

The internet tells me that the Sheeva uses about 5 Watts of power.
Along with my wireless router and DSL modem I might be under 10 Watts,
but I really don't know how much power a wireless modem uses.

Oh and I also have native IPv6 on my DSL.  I like to brag about that
whenever I can.

This may be an interesting read, it uses a plugcomputer:

Admittedly I don't have a need for a full blown home lab since I am not a
network engineer, I'm more of a sysadmin/network admin/programmer kind of
person... So I can make do with a somewhat minimal set up. But I *do* have
tunneled IPv6 from home ;-)

In my current apartment in addition to an el cheapo DSL modem that probably
wastes about 10 watts and a "sometimes on" PC workstation I used to have an
always on thinkpad (early 2000s model) as my main desktop system and an
always on G4 system (pegasos2 in case you care) acting as a mail/web/ssh
server. The thinkpad was a refurbished model and it was quite stable, up to
500 days of uptime during its last years. But the hardware slowly
disintegrated and when the gfx card died I retired it.

Right now my always on server is a VIA artigo 1100 pico-itx system
(replacing the G4 system) and my "router/firewall/modem" is still the el
cheapo DSL modem (which runs busybox by the way). I have an upgraded
workstation that's "sometimes on", it has a mini itx form factor (AMD
phenom2 CPU). I use debian on all systems.

I haven't measured it but I think if the set up would use 30 watts
continuously (only taking the always on systems into account) it'd be a lot.
Of course it'll spike when I fire up the workstation.

It's not extremely energy efficient but compared to some setups I read about
it is. The next step would be to migrate to a plugcomputer or something
similar (http://plugcomputer.org/).

Any suggestions and ideas appreciated of course. :-)
