Are there ARM or Intel servers capable of the reliability and availability of the Z-Series in Parallel Sysplex operation where processing can continue uninterrupted even if one of a pair of data centers becomes unavailable?

If a change of platform is the real objective, why not compile the COBOL for the ARM or Intel server?

Running it inside a HA VM on an VMWare cluster would do, no?

It doesn't appear to be equivalent. If one site in a stretched cluster becomes suddenly available, the same batch processing application would not be running on the alternative site. The application would have to be restarted after the VM has been moved.
