I added two new, 24 disk shelves, to my 6220.
I plan to add 1 shelf to each controller.
I think I will create a 23 disk aggregate -- (21+2) and one hot spare. I will have one raid group size 11 and one size 10.
Does this seem like a reasonable implementation or is there a better one?

What type of disks will they be? SAS / SATA, etc.
If you have two raid gropus, there will be four parity disks. If you want a true 21 + 2, then you should set the raid group size to be 23 disks total, and have one raid group. But that would be a large raid group for large sized disks - since the rebuild time will be so long.
