I'm in search of some hardware that consumes a low amount of power for
use
as a test-bed for Linux, various coding projects, and LAN services.
- Low power consumption (10-15W ... maybe 30W at most)
- Must run Linux without too much fuss (CentOS or otherwise)
- Must have two NICs (fast ethernet or better)
- Memory - 1GB or better
- Can be configurable either via serial or VGA.
- Accepts a normal hard drive, not CF -- drive capacity is my concern.
- spare PCI slot is a _plus_ (extra NICs or whatever else)
- I'd like to keep the physical footprint to a minimum (size of a 1U
switch or so?)
The lowest-power x86 device I've used is an Alix 2d2 from PCEngines. Power consumption was about five watts, regardless of load. This has three 100 mbps NICs, a 32-bit x86 AMD Geode CPU, and 256 MB RAM soldered to the board. Has a built-in Compact Flash slot to use as a "hard drive". I ran OpenBSD on mine for years as a firewall/gateway/router for a home LAN (don't see why it wouldn't run CentOS). (I'm actually selling mine, email off list if interested.)
The Geode CPUs do not support PAE [0]. While CentOS 5.x would work, 6.x requires a kernel recompile (not complaining, but noting).
