Thanks for the input. So, I'm trying to meld the two replies and come up with a direction for my case and maybe a "rule of thumb" that I can use in the future (i.e., near future until new features come out in zfs) when I have external storage arrays that have built in RAID.
At the moment, I'm hearing that using h/w raid under my zfs may be better for some workloads and the h/w hot spare would be nice to have across multiple raid groups, but the checksum capabilities in zfs are basically nullified with single/multiple h/w lun's resulting in "reduced protection." Therefore, it sounds like I should be strongly leaning towards not using the hardware raid in external disk arrays and use them like a JBOD. When will Sun have "global hot spare" capability?
