Power consumption of the SheevaPlug

<p>

Various people were wondering how much power the SheevaPlug consumes
exactly.  Laurent Guerby, who runs the GCC Compile Farm, posted some
data today.  According to his measurements with an Energy Monitor 3000,
the SheevaPlug uses:

</p>

<table>

<tr><td>3.1W</td><td>just on, Linux booted</td></tr>
<tr><td>3.3W</td><td>serial</td></tr>
<tr><td>4.3W</td><td>serial + Ethernet</td></tr>
<tr><td>5.4W</td><td>serial + Ethernet + 100% CPU</td></tr>
<tr><td>6.0W</td><td>serial + Ethernet + USB disk</td></tr>
<tr><td>7.0W</td><td>serial + Ethernet + USB disk + 100% CPU</td></tr>

</table>

<p>

However, these figures should be seen as preliminary and relatively high
values since power management for Kirkwood has not been implemented in
the kernel yet.  In particular, the Kirkwood chip has SATA and PCI-E but
they could be turned off since they're not used by the SheevaPlug.  This
is currently not done in the kernel, so you can expect some improvements
in this area.
