We ran for several years with a z/10 and a z9, both ECs. I was concerned enough about speed difference that I configured an extra ICF engine on the z9. We ran with system managed duplex, so I didn't want to risk delays caused by mismatch. We seemed to run fine during that period. We operate here as much as possible on the go-to-the-well-once strategy. Overshooting the mark a bit seldom requires on-the-carpet explanation. Undershooting can be h*ll.

Does anyone have a gut feel, or can point me to some documentation about performance effects, or things to do/not do while running a parallel sysplex with one CF on a z196 and the other on a z10 BC? -- Mark Jacobs Time Customer Service Tampa, FL ---- The quiet ones are the ones that change the universe...
