5.1 Types of Installation

SUSE Linux Enterprise Server allows two different types of installation on IBM System 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 creation of hosted SUSE Linux Enterprise Server systems is also very easy, because it is possible to run several hundred Linux instances concurrently.

Installation from an FCP-Attached CD-ROM

An FCP-attached CD-ROM can be used to IPL in an LPAR or in VM mode. The installation data is read directly from the CD-ROM.
