I'm not so sure that's practical and necessary for the large memory systems

Last time I looked across a number of customers it was fairly common for LPARs
with hundreds of GB of memory to have paging space < 1x memory. Sometimes much
less. Those with Storage Class Memory we
Paging packs should be a minimum of 3X real memory. 1 to back main memory,
