After reading a number of threads where people list their huge and wasteful, but undoubtedly fun (and sometimes necessary?), home setups complete with dedicated rooms and aircos I felt inclined to ask who has attempted to make a really energy efficient setup? This may be an interesting read, it uses a plugcomputer: http://www.theregister.co.uk/2010/11/11/diy_zero_energy_home_server/page2.ht... 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. :-) Thanks, Jeroen -- Earthquake Magnitude: 3.0 Date: Wednesday, February 22, 2012 13:57:33 UTC Location: Island of Hawaii, Hawaii Latitude: 19.4252; Longitude: -155.3207 Depth: 3.90 km
