My idea is rather that the "hot spares" (or perhaps we should say "cold spares" then) are off all the time until they are needed or when a user initiated/scheduled system integrity check is being conducted. They could go up for a "test spin" at each occasion a scrub is initiated which is not too frequently.
Solaris does include a power management function which is cable of spinning down idle disks. The disks are then spun up if they are accessed.
Perhaps I was a little too conclusive with my assumptions regarding ZFS and OpenSolaris. I figured that real enterprise applications rather use Solaris together with carefully selected hardware whereas OpenSolaris is more aimed at lower-budget/mainstream applications as a way of gaining a wider acceptance for OpenSolaris and ZFS (and of course to help the development of Solaris too, unless there are other plans ...). It has been discussed in many places that file systems do not change as frequently as the operating systems which is considered to be an issue when it comes to the implementation of newer and better technology.
It seems that most of your assumptions about Solaris/OpenSolaris are completely bogus and based on some other operating system.
