If you can fully trust the SAN then there's no reason not to run ZFS on top of it with no ZFS mirrors and no RAID-Z. Yet at the same time we see posters worried about ZFS failure modes in the face of corrupted data. Which is it: do you trust the SAN, yes or no? If you do then you're saying that you trust your filesystems not to have any failure modes upon SAN data corruption because you trust SAN data corruption to be impossible.
