Hello,
I'm rather new to FreeNAS (and the BSDs) and i'm trying to reduce the power consumption. It's a 4x drive home server which sits idle most of the day. It draws 120 watts, continually, and does not seem to lower the load at all. I've spent quite a bit of time looking for answers, so I apologize if I missed an obvious (RTFM!) answer. I am measuring the power consumption with a Kill-a-watt meter, fwiw.
The montherboard's settings could be responsible but I have them set for as power-efficient as I can. That includes the AMD Cool n Quiet.
Within FreeNAS Powerd is enabled (I see no options to set, just an on/off). The disks are spinning down.
I've tried adding sysctl settings, guessing at what it should be, with no luck. the sysctl command shows the 3 CPUs with a supposed state of "C1" but it should support C2, C3, so I think that's the issue (but may be wrong here... i'm a n00b)
CPU: AMD A6-3500 APU with AMD Radeon 6530 HD Graphics 2.1/2.4GHz Socket FM1 65W Triple-Core
Board: MSI A75MA-P35
