So is it better to use the mobo or the windoze way of powering down the hard drive on render nodes?
I am actually a nut for this power saving stuff! Say you are using 6-8 watts to keep a disk spun up. Over 10 computers that could be 80 watts being burned for no reason, 24/7.
80w x 24h = 1920 wh =~ 2KwH/day., x 30 = 60 KwH/month.
When your bill is for 1200 KwH/Month that may not seem like a lot, but it is by the method of plugging up these little "leaks" that we reduce a flood of wasted energy to a trickle. We had to do a lot of little things to reduce our usage. Remember, especially in summer, in an air-conditioned building, every watt saved inside yer building translates into 3 watts in total energy savings, assuming a 50% ac efficiency, so now we are talking about 180 KwH/month, free savings, just for changing a BIOS setting. As another poster mentioned in another thread, the drives may not be accessed at all on a long render if the ram is enough :D
It is by doing a lot of things like this that we reduced our energy needs by 2/3, and I am not done yet. Cost control is the rulez.
