No. Which workloads do you have that need more than 40 cores per image, are happy with a maximum of a hundred on, and won't run on clusters? (I hope it's not one that's going to be crippled by zVM's slow scan of large memory areas suspending guest execution).

Is zVM offering sysplex? No. So you're relying on your single LPAR to be five nines? Never upgrading zVM? Never updating PR/SM?
Is the datacentre five 9s? The power? The network? Really?
