There will always be some place where errors can be introduced and go on undetected. But some parts of the system are more error prone than others, and ZFS targets the most error prone of them: rotating rust. For the rest, make sure you have ECC memory, that you're using secure NFS (with krb5i or krb5p), and the probability of undetectable data corruption errors should be much closer to zero than what you'd get with other systems. That said, there's a proposal to add end-to-end data checksumming over NFSv4 (see the IETF NFSv4 WG list archives). That proposal can't protect meta-data, and it doesn't remove any one type of data corruption error on the client side, but it does on the server side.
