Installation Types - Novell LINUX ENTERPRISE SERVER 10 SP3 - ARCHITECTURE-SPECIFIC Supplementary Manual

1.2 Installation Types

This section gives an overview of the different types of installation possible with SUSE
Linux Enterprise Server for IBM System z. Basically, these two types are given:
LPAR , LPAR
Installation of SUSE Linux Enterprise Server using a logical partition (LPAR).
VM (z/VM)
Installation of SUSE Linux Enterprise Server as as a guest operating system within
z/VM.
Depending on the mode of installation (LPAR or VM), there are different possibilities
for starting the installation process and IPLing the installed system.
1.2.1 LPAR
If you install SUSE Linux Enterprise Server for IBM System z into a separate logical
partition (LPAR), allow SUSE Linux Enterprise Server to use a special part of physical
memory in your system. Also decide how many processors are used by SUSE Linux
Enterprise Server. In this mode, you can run different operating systems simultaneously
on your IBM System z system.
1.2.2 z/VM
Running SUSE Linux Enterprise Server for IBM System z in z/VM means that SUSE
Linux Enterprise Server is a guest system within z/VM. An advantage of this mode is
that you have full control over SUSE Linux Enterprise Server from z/VM. This is very
helpful for kernel development or kernel-based debugging. It is also very easy to add
or remove hardware to and from Linux guests. Creating additional SUSE Linux Enter-
prise Server guests is simple and you are able to run hundreds of Linux instances simul-
taneously.
