Boy, do I want answers too! We have HD's that run 24X7. And I don't want to turn them off, I just want them to sleep quietly until needed. We have lot's of RAM, thus plenty of cache space. Our machines are all blades. (Does this matter? I don't know.) IBMs and Super-Micros. We spend zillions of bucks on electricity; We use these machines 24X7 now, but soon will only need them about 12 hours a day. Is 24X7 operation the optimal strategy? What's the best course here, wrt electric costs, and wrt disk failures? --jg On Apr 8, 2007, at 2:10 PM, Yuri Grebenkin wrote: > Just wonder if it's better for an HDD not to spindown at all. > Maybe it's safer to spin in peace than to park/launch? > What do you think? > >> Hello again all, >> I was wondering if there was an automatic, and possibly timed >> means to >> spin down disks available in either ports or the base system, by >> chance. >> Just trying to cut down on energy use, and increase my disks' >> lives :). >> TIA, >> -Garrett > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions- > unsubscribe@freebsd.org"
