You can (and should) span multiple shelves in an aggregate. You can turn on 'options raid.raid_dp.raidsize.override' which allows you to grow past 16 disks for raid_dp, but not more then 19 disks 1T drives in a single array (the size limit kicks in). In 7.3RC1 you can move to 21 disks in a single aggregate. We do that here a lot and (knock on wood) haven't had any serious failures.
GX let's you get around the 16T aggregate (12T usable space.. boo) limit by overlaying several volumes. But not all applications call for gx (yet) so ymmv on that.

is the raid group recommended size still 16 with the new 1TB sata drives? basically we are pretty much limited to one shelf per aggregate--not sure how this is good thing.
is the 16tb limit going away anytime soon? it is becoming increasingly too restrictive as these larger drive sizes are introduced. or am i just supposed to create one shelf aggregates of 1tb drives from now on?
