This is a good approach, but please one reminder. The DAT structures for virtual disk in storage address spaces, including PGMBKs, are not pageable (user space PGMBKs are). And prior to z/VM 5.3.0, they must reside in real memory below 2GB. So 275GB of vdisk would be more than 2GB of memory required below 2GB for the DAT structures. One would want to be on z/VM 5.3.0. The PGMBKs are not reflected in the PTRM numbers.
