ZFS Redundacy

1. Mirroring – RAID – 1
2. RAID – 5 – RAID -Z

AVAILABLE DISK SELECTIONS:
       0. c0d0 <DEFAULT cyl 2607 alt 2 hd 255 sec 63>
          /pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
       1. c0d1 <DEFAULT cyl 1303 alt 2 hd 255 sec 63>
          /pci@0,0/pci-ide@7,1/ide@0/cmdk@1,0
       2. c1d1 <DEFAULT cyl 1303 alt 2 hd 255 sec 63>
          /pci@0,0/pci-ide@7,1/ide@1/cmdk@1,0

Virtual Devices:
1. c0d1 – 10.0G
2. c1d1 – 10.0G

Note: Redundacy/Replication is associated directly with the pool

Tip: For PRODUCTION enviroments ideally you should implement your mirror, raid z, straight volumnes dedicating THE ENTIRE DISK to zfs (the disks should be the same )
