That's a seperate argument/issue right there for me, but what the client wants is what the client wants. Has anyone ran Postgres with software RAID or LVM on a production box? What have been your experience? I don't forsee more 10-15 concurrent sessions running for an their OLTP application. Thanks. Steve Poe
