System Requirements

Minimum Linux server system requirements for installation

  • Local Installation: 1024 MiB RAM, 512 MiB Swap recommended
  • 2 GiB available disk space (more recommended, 8.5 GiB for all patterns)
  • 32 GiB for snapshot/rollback of the OS

Recommendations for specific uses

1 GiB to 8 GiB RAM, at least 512 MiB per CPU
8 GiB hard-disk space, 32 GiB for snapshot/rollback of the OS
Network interface
For print servers - a faster processor or additional processors to improve server-based printing
For web servers - additional RAM to improve caching, and additional processors to improve web application performance
For database servers - additional RAM to improve caching, and multiple disks for parallel I/O
For file servers - additional memory and disks, or a RAID system to improve I/O throughput

Download and Installation

We offer two media types for installation:

  • A media for online installation ("SLE-15-SP6-Online-*-GM-Media1.iso") which can be used if you have a connection to either SCC, RMT or SMT, which only consists of the installer. During the installation you will have the option to select which product to install and to add functionality. This is done by the activation of additional modules. A default installation requires network access to either contact the SUSE Customer Center or a local Repository Mirroring Tool server to retrieve repository data for the modules.
  • In case you want to perform an installation without network access, use the full installation media ("SLE-15-SP6-Full-*-GM-Media1.iso"). This contains all packages but is rather big.

Media Selection

For both the Online as well as the Full Medium we offer two variants:

  • The first, containing 'GM' in the filename, consists of the package set as shipped at first customer shipment date
  • The second, identified by a 'QU' followed by a number in the filename, consists of the packages shipped at first customer ship. But all packages where maintenance updates have been released since then have been updated to the latest maintenance update. Quarterly updated media are refreshed every 3 months, with the first coming three month after the 'GM' release

You only need either the 'GM' or the 'QU' media, not both. Which to choose, the GM or the QU version depends on your needs and preferences. If you have newer hardware, the QU version might be the better choice. The installation procedure is identical for both flavors.

For both flavors it is recommended to install the latest updates released since creating the images.

Both the installer medium and the packages medium are the same for all SLE products and only need to be downloaded once.

SUSE Linux Enterprise 15 SP6 is available for the following architectures. Images for a specific architecture can be identified by the respective acronym in the filenames:

Files with "x86_64" in the name are for the AMD64 and Intel* 64 platforms.
Files with "s390x" in the name are for IBM* z System or LinuxONE.
Files with "ppc64le" in the name are for the IBM* Power LE platform.
Files with "aarch64" in the name are for the Arm* 64 platform.

For each architecture and media flavour two images are available:

DVD1 Required for the installation
DVD2 Source code, only required to rebuild applications on the installer or packages medium.

Required downloads

The following downloads are required for each architecture you would like to install on:

  • Regular installation (with Internet access): Media1 of the Online medium
  • Offline installation (without internet access): Media1 of the Full medium

All other images are optional and not required for the installation.

Download the ISO images to a workstation or to a network drive.
Prepare booting into the installation system and start the installation and proceed as outlined here in the deployment guide.
