Installation Considerations
This chapter summarizes all decisions that must be made while planning an installation
of SUSE® Linux Enterprise Server on IBM System z hardware. The current hardware
and software requirements for installing SUSE Linux Enterprise Server on IBM System z
are listed in the manual Architecture-Specific Information, which is provided as a
printable PDF file in the directory /docu on the first installation medium.
5.1 Types of Installation
SUSE Linux Enterprise Server allows two different types of installation on IBM Sys-
tem z:
LPAR Installation
Installing SUSE Linux Enterprise Server for IBM System z on a separate logical
partition (LPAR) allows SUSE Linux Enterprise Server to use a specific portion
of the physical memory. It is furthermore possible to specify how many processors
should be used. This mode allows concurrently running multiple operating systems
on a system.
Installation in z/VM
z/VM mode runs SUSE Linux Enterprise Server for IBM System z as a hosted
system in z/VM (virtual machine). This type has the advantage that z/VM provides
full control over SUSE Linux Enterprise Server. This type of installation can prove
very helpful for kernel development or kernel-based debugging. It is furthermore
very easy to modify the hardware configuration of a hosted Linux system. The
