If you have the disk space to let you do a mirror of mirrors, you could create the pool from a series of 4 way mirrors, with each mirror containing 2 disks from each JBOD enclosure. This would give you the ability to sustain the simultaneous failure of an entire enclosure and at least one (though sometimes multiple) disk failure in the working enclosure. This would also be a pure ZFS solution.
