> a JBOD container or RAID-0 at the hardware level?
Yup. That's what I do. I had some Dell Power Edge 1950 servers with Red Hat
Linux on them that no one cared about, so I re-purposed them as OpenSolaris
test machines. Normally I put the RAID card in JBOD mode and use ZFS to mirror
or RAID-Z the disks, but unfortunately this particular ueber-crappy Perc RAID
card wouldn't let me JBOD the disks, so I take 4 disks and do it like this:
[ Disk 1 + Disk 2 ] Perc hardware RAID 0
> ZFS
mirror software RAID 1
[ Disk 3 + Disk 4 ] Perc hardware RAID 0
so I have two hardware RAID zeros in a ZFS mirror RAID 1, basically a RAID 10
configuration. The problem is that if both Disk 1 and Disk 3 fail at the same
time, I'm basically S.O.L. and can't recover any data, but I don't care anyway
because it's a test server. The performance with ZFS running on top of hardware
RAID 0 is also unbelievably fast.... the performance literally screams when I'm
copying large files or doing lots of disk reads and writes!
