Note the change of title from the obvious OTHER one. :-) And deliberate abstraction on MY part. :-)
The issue is with whether the Coupling Facility is too slow relative to the coupled z/OS images. Just to be clear: Not whether the images are on different speed engines. Moving on, it has been demonstrated that the CF engine needs to be reasonably close to the coupled engine speed else there is a risk of capacity loss. It is also true that lots of other things can affect this, such as the oft-mentioned Sync to Async conversion algorithms, distance, LPAR setup etc. (There was also something about different processor families being able to participate in the same plex whether directly coupled together or via a third CF LPAR. The usual research considerations apply.) Now, don't expect ANY IBMer to bite here on any hypothetical unannounced ANYTHING. :-) Martin Packer Performance Consultant IBM United Kingdom Ltd +44-20-8832-5167 +44-7802-245-584 [EMAIL PROTECTED] Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
