[geeks] solaris x86 cpu speed control

[Shannon]

Question:

I would like to have my Solaris server put the CPU cores in their slowest
possible state at nite and other times to reduce power use and (mostly)
noise.

This is an AMD system that can vary from 1-3GHz speeds in several steps.

At 1GHz, you can barely hear it run, so I'd like some way to force it to run
that slow, even if there are jobs active that would normally force stepping
control to run the CPU fast.

Is this possible and what X86 Solaris software would do it?

--------------------

I'm eventually going to move away from Solaris on this server, and I'm looking
for good alternatives.  Any experiences with similar CPU speed control on
other OS also appreciated.
