I''m just wondering what some of you might do with your systems. We have an EMC Clariion unit that I connect several sun machines to. I allow the EMC to do it''s hardware raid5 for several luns and then I stripe them together. I considered using raidz and just configuring the EMC as a JBOD, but I thought it would defeat the purpose paying so much for a system with the advanced redundancy system. I also like to add luns on the fly when a system needs more file space and I know you can''t do that with raidz. I''ve never had a lun go bad but bad things do happen. Does anyone else use ZFS in this way? Is this an unrecommended setup? It''s too late to change my setup, but in the future when I''m planning new systems, should I consider the effort to allow zfs fully control all the disks?

Is this an unrecommended setup?We used ZFS like this on a Hitachi array for 3 years. Worked fine, not one bad block/checksum error detected. Still using it on an old Sun 6120 array, too.> It''s too late to change my > setup, but in the future when I''m planning new systems, should I consider the > effort to allow zfs fully control all the disks?Well, you should certainly consider all the alternatives you can afford. Our customers happen to like cheap bulk storage, so we have a Thumper, and a few SAS-connected Sun J4000 SATA JBOD''s. But our grant-funded researchers may not be a "typical" customer mix....
