Cecelia,
We moved from VM/ESA 2.4.0 (and you thought you took a big leap!) New Year's eve 2005/2006. Here's our current page allocation on a Monday morning, after a scheduled Sunday evening IPL and VM:Backups running from

Obviously, we have a few more full-pack 3390-3 DASD dedicated to paging. Even so, the total "PAGES IN USE" are remarkable similar.

Our production system was migrated from z/VM 3.1 to z/VM 5.1 over the
weekend.
The paging rate was high this morning on the production system as the
VM:Backup backups were running. (It was paging over 2000 pages per second.)
When I did a Q ALLOC PAGE, it indicated the percentage used was 55%.
Presently (the backups have completed):

Being the system utilization is still low, I am a bit apprehensive as to
what will occur when the system gets busy through the day... Shouldn't the
Q ALLOC PAGE percentage used have dropped?
Thank you.
