But facts are more imprtant than opinion.
>1. Sharing memory resource is not true.
Of course it's true, especially when running under z/VM. Even without
z/VM there are IP links between images implemented via shared memory.
>2. Usually all the servers have workload peak in the same time.
There is no "usually". Each shop has its own workload. You may see a
peak of CPU-intensive work on all servers concurrently; that wouldn't
mean that most other shops do.

Not once you take into account environmental, personnel, software and
support costs for large server farms.
