Geo Clustering for SUSE Linux Enterprise High Availability Extension
When you need maximum protection for a workload that can never have unplanned downtime, and you have data centers in different places around the globe, you can protect the workload using geo clustering.
Geo Clustering lets you deploy physical and virtual Linux clusters between data centers located anywhere in the world.
Geo Clustering extends the capabilities of SUSE Linux Enterprise High Availability Extension across unlimited distances. Even in a regional disaster, your mission-critical Linux workloads will continue to run. With Geo Clustering for SUSE Linux Enterprise High Availability Extension, your organization can maintain business continuity, protect data integrity, and minimize unplanned downtime.
About Geo Clusters
Geo clusters are typically built between groups of local or metro area clusters. If an unexpected event causes a workload to fail–such as a hardware failure, or a flood in your data center–SUSE Linux Enterprise High Availability Extension will first transfer the failing workload within the local or metro area cluster. This keeps the service near its local user and infrastructure while minimizing latency.
However, with a large-scale disaster–such as an earthquake or blackout that affects the entire cluster–the workload must be restarted on another cluster far away from the disaster. And that means downtime.
For your mission-critical workloads even a little downtime is not acceptable. Significant downtime can result in missed revenue opportunities and permanently lost customers. When you need maximum protection for a workload that can never have unplanned downtime, and you have data centers in different parts of the world, you can protect the workload using Geo Clustering.
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.
Manual failover is an important option in some cases, because it:
- Helps you comply with industry regulations or your internal approval processes
- Gives you maximum control over the movement of applications around the world
- Ensures that other necessary resources are also assigned or moved
When a regional disaster strikes one of your data centers, Geo Clustering helps your enterprise meet all service level agreements, and maintain compliance with corporate policies and external regulations.
