Power-wise, one thing that never really satisfied me about the setup was that it was hard to spin down disks. I never really dug into why but suspect ZFS is fairly 'chatty' with the underlying storage which prevented the spindown timeout being reached. Can anyone who's looked more closely confirm or deny this?
Yes; YMMV but according to http://n40l.wikia.com/wiki/Wake-on-Lan_(WOL) everything in the Microserver family does support WoL.
