First, you won't need a RAID controller. Just get something cheap with lots of ports. It'll suffice - ZFS will do the smart stuff. > I was thinking of zpools: 2+2+1 X 4 in ZRAID2.

If I were to use 2Tb drives, each zpool would be 10Tb RAW and > 6TB useable… giving me a total of 40Tb RAW and 24Tb usable… I don't see the point of using more than one pool. Just use more VDEVs in the same pool, and redundancy will be just as good as with more pools, and a single pool is far more flexible.
