Mark,
I have done that before actually, when the tablespace patch came out. I
was able to get almost 40% more throughput with half the drives than
striping all the disks together.
That's not the figures you showed me. In your report last year it was 14%,
not 40%.

Have you tried non-RAID SCSI controllers in this configuration? When we
used the Adaptec 2120s previously, we got very poor

I'm starting to get results with dbt2 on a 4-way opteron system and
wanted to share what I've got so far since people have told me in the

I've been using.
