Yes, how to maximize parallelism is the pertinent question. Let's assume for the sake of argument, DS88xx with no SSD. Mix of 3390-3, -9, and -27; HiperPAV enabled, with DASD defined as SHARED in the IODF, and some shared across Sysplex boundaries (understood this is not utopian, but some customers do it, either self-managed or with the assistance of MIM/MII). How do you spread that 100GB across the farm, assuming you have at least 45 mod-3 equivalents? (If my math is not too far off, there's about 2.2GB of usable page space on a mod-3). What would one avoid so as not to handcuff HPAV?
