When i have run into this kind of problem (a RAID unit that either
does not support JBOD or one drive per LUN or enough LUNs), I usually
carve the array disks into small sets of RAID0 and present those to
ZFS. Currently I am reusing some old Sun 3511 arrays, each loaded with
12 x 500GB drives. The 3511 supports one drive LUNs, but discourages
their use (it is for support use only according to the documentation),
so I created RAID0 sets of 2 drives each and ZFS sees 6 x 1TB LUNs.
ZFS then provides my redundancy and data integrity.
