GSG, It seems on the surface to be a prudent topology to have dedicated resources for production (1 LPAR) and isolation from TEST/DEVL workloads (another LPAR). WLM has made significant inroads into controlling workloads on a single LPAR, so there are no real resource distribution issues.
With that stated: (IMHO) 1. COST - If the figures add up on ISV software savings, that alone could justify two LPARS. 2. Quality Assurance - The ability to roll out software releases and have technical testers by default (application developers) before migration to PROD is a definite PRO. 3. Web Presence - If the mainframe supports your company WEB presence, targeting a 99.99999% uptime solution is another PRO. 4. Planning and Procedures for operating the two LPARS should not be taken lightly. Whether to share or not to share DASD, Production migration of SOURCE & LOAD MODULES. If your have a significant NETWORK, investigate a Communication LPAR where all of your NETWORK access resides.

All feedback is welcome.
