SUSE Manager - System Requirements
SUSE Manager Server is a 64bit Java application with an Oracle/PostgreSQL database backend. This requires sufficient CPU power and main memory. A multi-core 64bit CPU (x86_64) is required, accompanied with 4 to 8 GB of main memory.
The SUSE Manager Server database contains every information required to manage clients. This includes all installable packages and updates as well as lists of installed packages for every client. This data requires a lot of storage space on the hard disk, typically 50 GB or more per package repository (go to https://www.suse.com/support/kb/doc.php?id=7015050 for more details about SUSE Manager disk space requirements).
See the Installation & Troubleshooting Guide for more details on the system requirements.
