Frank, The only resources that we separate is the sandbox where system programmers do dangerous things like bringing up new levels of operating systems, etc. z/OS has always had robust sharing.
I/O from the development LPAR would have negliable impact on production LPAR even reading the same exact data since data is staged through cache on all modern dasd subsystems. You just need to be sure that GRS is setup to convert hardware reserves to enqueues and have everyone use DISP=SHR unless they really need to update the dataset.
