I agree completely with this; the hardware part is the final piecec to the puzzle.

We've tunined the SQL and other processes as much as possible. The performance we're getting matches our collective experience. It still impresses me how changes to the SQL can cut processes from days to a few minutes.

We're not finding more places to tune unless we partition the tables, which will be an interesting experiment. Your comment about the SANs in organizations struck a cord with me.

The standard process at the company is to take a SAN and format it to work like a single disk or LUN. The IS group claims their's no benefit to keeping things in individual disks since the SAN's cache will handle it. I've long had doubts on this. Do the v$ tables show the hotspots even on a single SAN disk?
