zIIPs can do all that? Numerous new large zIIP users and potential for less
zIIP capacity. Customers need to analyze, especially before z16 upgrade. If you
are sub-capacity CPC 4xx-6xx and upgrade to a z16 you will have a lower zIIP to
GCP ratio if you are at the max or if you don't buy more. With zCX and System
Recovery zIIP boost on top of all the old and new software you may be running
out. Worse yet many customers have overflow to GCP just because their zIIPs are
in the wrong place. There are multiple ways (HiperDispatch, SMT-2, Flex
Capacity) to avoid these issues which will be discussed.
