if the OP were so inclined,
he could craft a couple of "striped" pools (300+500) and
then make a ZFS pool over these two.
Actually, you can't do that. You can't make a vdev from other vdev's, and when
it comes to striping and mirroring your only choice is to do it the right way.
Yup, that's what i said later in the post.
If you were REALLY trying to go out of your way to do it wrong somehow, I
suppose you could probably make a zvol from a stripe, and then export it to
yourself via iscsi, repeat with another zvol, and then mirror the two iscsi
targets. ;-) You might even be able to do the same crazy thing with simply
zvol's and no iscsi... But either way you'd really be going out of your way to
create a problem. ;-)
Theoretically, at least, you could do that.
AFAIK you can even do it without iSCSI by just addressing
zvol device names with their full paths, an yes after crafting
yourself an intricate problem you'd likely get one ;)
Not that it's impossible or forbidden to shoot oneself in the
foot, as your and my adventures demonstrate quite well ;)
