I think the storage server I'm working on at home (current omnios stable) is

long time to respond, and then goes back to normal.
My current power.conf is:
-----
autopm enable
autoS3 disable
cpupm enable
cpu_deep_idle enable
cpu-threshold 1s

I had thought that when running on server class hardware the default was not
to spin down drives, but perhaps I was mistaken? Hmm, or maybe the default
is to just skip power management completely, and explicitly turning it on
turned on everything.
There's also a setting in ata.conf for programming IDE disks.
If standby is not set to >= 0, then I think the disks will keep their
previous setting (from another OS having set them, or from the BIOS
settings).
