z/VM Virtual Server pane: Memory page

Use the Memory page to view information about the memory used by the z/VM virtual server. You can also edit the description for the memory.

Introduction

In z/VM terminology, the virtual memory that is described on this page is referred to as virtual storage. Operating systems that run on a z/VM virtual server perceive this as their real memory. When a z/VM virtual server is started it is given a specified initial memory size.

You can issue the z/VM control program DEFINE STORAGE command to change the memory size up to a specified maximum size while the z/VM virtual server is active. You do not have to reactivate the z/VM virtual server to use the changed memory range but you need to reboot the operating system that runs on it. Refer to z/VM® CP Command and Utility Reference, SC24-6081, for details.
