We recently upgraded from a 9672-R16 to a z9 BC G01 and in the
process went from having 2 GB storage to having 8 GB. HSA takes a
bunch more than it did, but we still have lots of extra storage to play with.
We run 4 LPARs - production z/OS and z/VM and test z/OS and
z/VM. Right now we're running with about the same LPAR storage
allocations that we had before, and see very little paging on any of
our LPARs. The one exception is when we run an image of our
production z/OS system under our test z/VM system for Disaster
Recovery testing. Then we see lots of paging.
We plan to allocate additional storage to the test z/VM system to
better accommodate the z/OS DR testing. But we're not sure if we
would benefit by allocating additional storage anywhere else, in
particular to our production z/OS and z/VM systems.
Since we're not paging on those systems, would we get any benefit
from allocating additional storage to them? Or would we just be
spending DASD space (because the backing store for paging would have
to be bigger to accommodate the additional storage) for no benefit?
Thanks,
Mark
