-----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Bill Bitner Sent: Friday, May 02, 2008 8:51 AM To: [email protected] Subject: Maximum Central Storage The support statement for z/VM 5.2 was 128GB, but from a practical standpoint, the value might be slightly lower. It is workload dependent. The key variable to watch is how much memory below 2GB is being consumed by PTRM space. See my share presentation: http://shareew.prod.web.sba.com/proceedingmod/abstract.cfm?abstract_id=1 6913 for more details on measuring PTRM space usage. When it gets to 1GB of resident PTRM, consider that the yellow line. 1.5GB is the red line. z/VM 4.4 is not supported at all anymore :-). From a practical standpoint, I used to get nervous at about 16GB.
