ZFS on Hardware RAID

[Maciej Jan Broniarz]

Hi,

I want to use ZFS on a hardware-raid array. I have no option of making it JBOD. I know it is best to use ZFS on JBOD, but 
that possible in that particular case. My question is - how bad of an idea is it. I have read very different opinions on that subject, but none of them seems conclusive.

Any comments and especially case studies are most welcome.
All best,
mjb
