Geo Clustering for SUSE Linux Enterprise High Availability Extension

In the event of a regional disaster, the power can go down and your mission-critical workloads can fail. This is not acceptable. Geo Clustering for SUSE Linux Enterprise High Availability Extension provides rules-based failover for automatic and manual transfer of a workload to another cluster outside of the affected area. Your mission-critical workloads are transferred away from the affected region to continue to run.

Key Benefits
  • Protect workloads across globally distributed data centers
  • Use multi-tenancy to manage geo clusters per business needs
  • Achieve maximum protection for workloads that can never have unplanned downtime
  • Comply with industrial regulations with manual failover option
  • Protect mission-critical applications from regional disasters
  • Deploy physical and virtual Linux clusters across data centers

System Requirements

Recommendations for specific uses
  • 512 MiB to 4 GiB RAM, at least 256 MiB per CPU
  • 4 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
(Continued)
  • 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

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