System Requirements

Minimum Linux server system requirements
  • Local installation: 512 MiB RAM, 512 MiB Swap recommended
  • 2 GiB available disk space (more recommended, 8.5 GiB for all patterns)
  • 16 GiB for snapshot/rollback of the OS

*System requirements are identical when using Geo Clustering for SUSE Linux Enterprise High Availability Extension in conjunction with SUSE Linux Enterprise High Availability Extension.

Recommendations for specific uses
  • 512 MiB to 4 GiB RAM, at least 256 MiB per CPU
  • 44 GiB hard disk space, 16 GiB for snapshot/rollback of the OS
  • Network interface (ethernet, wireless or modem)
  • Network redundancy
  • I/O fencing mechanism and possibly shared storage
  • For Xen virtual host server? at least 512 MiB RAM for each virtual host server
  • For KVM virtual host server? KVM's limits are equal to those of SUSE Linux Enterprise Server
  • For Xen or KVM virtual machines? at least an additional 256 MiB RAM for each virtual machine
  • For print servers? a relatively 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 using multiple disks for parallel I/O
  • For file servers ? additional memory and disks, or a Redundant Array of Inexpensive Disks (RAID) system to improve I/O throughput
