Thanks for the feedback! This does sound like what we're hitting. From our testing, you are absolutely correct--separating out the parts is a major help. The big problem we still see, though, is doing the clones/recoveries. The DBA group clones the production environment for Education. Since both of these instances live on the same server and ZPool/filesystem, this kills the throughput. When doing cloning or backups to a different area, whether UFS or ZFS, we don't have the issues.
I'll know for sure later today or tomorrow, but it sounds like they are seriously considering the ASM route. Since we will be going to RAC later this year, this move makes the most sense. We'll just have to hope that the DBA group gets a better understanding of LUN's and our SAN, as they'll be taking over part of the disk (LUN) management. :-/ We were hoping we could get some interrim relief on the ZFS front through tuning or something, but if what you're saying is correct (and it sounds like it is), we may be out of luck. Thanks very much for the feedback.
