Let ontap figure where to put things.
Besides,. the recommended size is 14 for SATA and 16 for FC per raid group. Obviously, if you want to MAX out an aggregate at 16TB, you have to take into consideration you cannot do it in a single RAID group (well, I think you can, but it is not recommended!!). Therefore, your raid groups may look like 8+8 (maybe even 9+9), but you probably do not want 14+2 or 14+4.
Either way, you are eating the parity drives. Might as well make them balanced groups.
Oh, one more thing. Let ONTAP pick which disks to use. It will intelligently pick across shelves and controllers.

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?
