The latest Intel and AMD cpus should be supported with cpu power management under current OpenSolaris. Problem is that "old" Intel and AMD cpus (and that includes the AMD X2 cpus) do not have cpu power management support with OpenSolaris. Disk power management for S-ATA (and SCSI) HDDs can be configured in /etc/power.conf . SX:CE has a gui to configure this (sdtpower). For OpenSolaris you have to figure out the correct physical device paths for the HDD(s) and construct an /etc/power.conf file similar to this: # cat /etc/power.conf ... device-dependency-property removable-media /dev/fb autoS3 default S3-support enable autopm enable cpupm enable cpu-threshold 1s # Auto-Shutdown Idle(min) Start/Finish(hh:mm) Behavior autoshutdown 0 0:00 0:00 noshutdown device-thresholds /pci at 0,0/pci1043,8239 at 5,1/disk at 0,0 1200s device-thresholds /pci at 0,0/pci1043,8239 at 5/disk at 0,0 1200s -- This message posted from opensolaris.org
