Just another "I hate sysplex" message from me. No, don't bother to justify

Sysplex *is* justifiable on one box.
With a good sysplex design, you can shift all production work to the other
LPAR, then shut down the idle one and IPL at any time. Then shift all the
work to the upgraded LPAR and IPL the other one. It could mean zero
downtime to do a software upgrade. And zero risk if something makes the IPL
take longer.
Upgrades, PTFs, etc.
However there are also disadvantages. The major one is cost. More cycles
consumed, more storage, ICF.
