Downloading SLES
You can standardize on SUSE Linux Enterprise with expanded support by downloading SLES 15 at https://www.suse.com/
download-linux/.
Installation prerequisites
Minimum Linux server system requirements
● Local installation: 1024 MiB RAM, and 512 MiB Swap recommended
● 2 GiB available disk space (more disk space recommended, 8.5 GiB for all patterns)
● 32 GiB for snapshot or rollback of the operating system
Recommendations for specific uses
● 1–8 GiB RAM, at least 512 MiB per CPU
● 8 GiB hard-disk space, 32 GiB for snapshot or rollback of the operating system
● Network interface
● For print servers—a faster processor or more processors are required to improve server-based printing
● For web servers—more RAM to improve caching, and more processors are required to improve web application performance
● For database servers—more RAM to improve caching, and multiple disks for parallel I/O
● For file servers—more memory and disks, or a Redundant Array of Inexpensive Disks (RAID) system to improve I/O
throughput
