Is it possible to construct a RAID-10 array with ZFS? I've read

the ZFS documentation, and it appears that the only way to create a

in ZFS and combine those to create the outer RAID-0 volume.
Am I approaching this in the wrong way? Should I be using SVM to
create
my RAID-1 volumes and then create a ZFS filesystem from those
volumes?
No - don't do that. Here is a ZFS version of a RAID 10 config with 4
disks:

To further agree with/illustrate Al's point, here's an example of
'zpool status' output which reflects this type of configuration:
(Note that there is one mirror set for each pair of drives. In this
case, drive 1 on crontroller 3 is mirrored to drive 1 on controller
4, and so on. This will ensure continuity should one controller/buss/
cable fail.)
