Hello,

Is there a downside to over-allocating real storage on an LPAR?

We will be upgrading current processors which are tired and soon to be out
of service to z13's which will have 4 times the storage we have at present.

We don't have any issues with paging or UIC etc. but I feel that on the new
processors, I need to make use of most if not all that available storage.

Some of my thoughts are;

- Will the additional storage be used on an LPAR which already has enough
to do it's work.
- Is there a way to monitor for 'unused' storage?
- If the storage is not used, is there a loss of cycles in an 'overhead' to
managing this unused storage?
- etc.

Your comments will be appreciated.
