See, telling folks "you should just use JBOD" when they don't have JBOD and have invested millions to get to state they're in where they're efficiently utilizing their storage via a SAN infrastructure is just plain one big waste of everyone's time. Shouting down the advantages of storage arrays with the same arguments over and over without providing an answer to the customer problem doesn't do anyone any good. So. I'll restate the question. I have a 10TB database that's spread over 20 storage arrays that I'd like to migrate to ZFS. How should I configure the storage array? Let's at least get that conversation moving...
In general, I'd say that if the storage has battery-backed cache, use RAID5 on the storage device - limit the amount of redundant data, but improve performance and achieve some data protection in fast special-purpose hardware.
