This is an interesting discussion. It appears that there is indeed some work to
be done with manipulating spin up/down on subsections of an array, etc.
However, in terms of cost/performance for small systems, it may be simpler to
solve this with less programming and more hardware. The cost of a

You know, it's just going to de
Thanks for the link, but the main concern in spinning down drives of a ZFS pool
is that ZFS by default is not so idle. Every 5 to 30 seconds it closes a
transaction
group (TXG) which requires a synchronous write of metadata to disk.
I mentioned reading many blogs/forums on the matter, and some
I read about some guy that shut off his RAID when he didnt use it. And he had a
large system disc he used for temporary storage. So he copied everything to the
temp storage and immediately shut down the raid.

And thanks for the link to the article.
The article specifies SAS and SCSI a lot; does this also apply to SATA?

You've been able to spin down drives since about Solaris 8.
