Is their a solution to the following problem:

I want to present two 1.5 TB drives to my freeNAS box and stripe them together to form one 3TB volume. I then in turn want to be able to present the 3TB volume as an iSCSI target?

I have set up device extents and presented those via iSCSI before, but it only allows you to select the individual 1.5 drives themselves. So if this is going to work, their would have to be a way to stripe the two drives first then present them via iSCSI..

Thoughts suggestions?

SO you want a stripe set (Hardware raid 0) + Device extent or a 2 disk ZFS pool with a single volume + ZFS device extent?

Doable, but if you loose one disk you loose all of your data across both disks.

Well I am not really worried about hardware failures because the underlying hardware is redundant via a RAID5 array. The 2 1.5TB drives are being presented to the freeNAS box as vmware vmdk files.

The multiple layers of indirection are going to kill performance. There's nothing stopping you from doing it, though.
