I haven't been following this too closely, but if the GCS segment is located within boundaries of the VTUBES virtual machine and you make common storage larger, then it proportionally reduces the private storage available to VTUBES. You can also use models and ISTEXCCS or ISTEXCSD (can't remember which) to create PUs dynamically, reducing the storage requirements in VTAM. I used to that in a former life.
