Geo Clustering for SUSE Linux Enterprise High Availability Extension

An industry-leading open source high availability system designed to manage cluster servers in data centers anywhere in the world. Geo clustering is included with the latest version of SUSE Linux Enterprise High Availability Extension, and available separately for version 12 and earlier. High availability clustering is used to automate application and data recovery.

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 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 Features

Flexible, policy-driven clustering and continuous data replication boost flexibility while improving service availability and resource utilization by supporting the mixed clustering of both physical and virtual Linux servers. Protect workloads across globally distributed data centers.
Rules-based failover or 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 and protect workloads across globally-distributed data centers against regional disruptive events.
Multi-tenancy can be used to manage geo clusters per business needs.

Mixed clustering of both physical and virtual Linux servers to boost flexibility while improving service availability and resource utilization.

HAProxy is a very fast and reliable solution that offers high availability, load balancing and proxying for TCP and HTTP-based applications by spreading requests across multiple servers. It complements the Linux virtual server load balancer.

Continuous data replication across cluster servers in data centers anywhere in the world and minimize data loss due to corruption or failure by protecting your data assets using your existing IT infrastructure. Achieve maximum protection for workloads that can never have unplanned downtime.
Distributed Replicated Block Device (DRBD) is a leading open source networked disk management tool, enabling you to build single partitions from multiple disks that mirror each other and make data highly available. You can also quickly restore your clustered services via its fast data resynchronization capabilities. DRBD mirrors the data from the active node of a high availability cluster to its standby node. DRBD supports both synchronous and asynchronous mirroring. In the event of an outage, DRBD automatically re-synchronizes the temporarily unavailable node to the latest version of data, without interfering with the service that is running. Additionally, DRBD includes data compression algorithms that reduce replication times.
