A couple of other things to consider to go with that recommendation. - never build a pool larger than you are willing to restore. Bad things can still happen that would require you to restore the entire pool. Convenience and SLAs aren't always in agreement :-) The advances in ZFS availability might make me look at my worst case restore scenario a little different though - but there will still be a restore case that worries me. - as I look at the recent lifecycle improvements with zones (in the Solaris 10 context of zones), I really like upgrade on attach. That means I will be slinging zones more freely. So I need to design my pools to match that philosophy. - if you are using clustering technologies, pools will go hand in hand with failover boundaries. So if I have multiple failover zones, I will have multiple pools.
