Re: Questions about running z/OS under z/VM

z/VM is not paging at all. All of the z/OS systems in that partition are test/dev systems. Performance is still good on these systems, however. Our only “production” z/OS system is in its own LPAR.

I take it that the first z/VM LPAR has enough storage so that z/VM paging is kept to a minumum.

We run 3 LPARs on our z890 w/16GB of storage. The first LPAR is a z/VM LPAR w/7GB of storage. It runs 8 z/OS systems w/storage sizes ranging from 384MB to 512MB. In the second LPAR, we run a single z/OS system w/4GB of storage. The third LPAR is our “Linux” LPAR with z/VM and a TBD number of Linux’s.

Subject: Questions about running z/OS under z/VM

I have four questions for running z/OS under z/VM.

1. What is your processor storage size ?

2. Do you run z/VM and z/OS in LPAR mode or z/VM in LPAR mode ?

3. How many z/OS systems do you run under z/VM ?

4. What are the storage size (min,max) of the z/OS systems under z/VM ?
