SUSE Geo Clustering for SUSE Linux Enterprise High Availability Extension allows you to cluster servers in data centers anywhere in the world. In the event of a regional disaster, the power can go down and your mission-critical workloads can fail. This is not acceptable. SUSE 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. 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.

SUSE HAProxy is a very fast and reliable solution offering high availability, load balancing and proxying for TCP and HTTP-based applications by spreading requests across multiple servers. With SUSE Linux Enterprise High Availability Extension 12 it includes support for HAProxy to complement the Linux virtual server load balancer. SUSE Geo clustering delivers failover across unlimited distances. Available with SUSE Geo Clustering for SUSE Linux Enterprise High Availability Extension subscription. Pacemaker is a highly scalable cluster resource manager with a flexible policy engine that supports n-node clusters. Corosync and OpenAIS allows clustering and distributed systems infrastructure components. Metro area clusters provides failover across data center locations as far as 30 kilometers apart. Storage-based quorum coverage prevents split-brain scenarios.

SUSE Geo Clustering — Linux Enterprise High Availability Extension

Ensure continuous access to your mission-critical applications and data. With this flexible, policy-driven clustering solution you don’t have to worry about service outages. Ensure that your most important applications continue to deliver business value. Service outages and interruptions to business processes can take a terrible toll on productivity, revenue, and customer relationships. In some cases, they can even have legal consequences. SUSE Linux Enterprise High Availability Extension helps you ensure that your most mission-critical applications continue to deliver business value, 24 hours a day, every day. It does this by using high availability clustering to automate application and data recovery. You can use our flexible, policy-driven clustering solution to implement highly available Linux clusters and eliminate single points of failure. Your servers are continuously monitored, and when a fault or failure occurs.

Cluster-Aware File System And Volume Management

A shared-disk, POSIX-compliant, generic cluster file system that enables the clustering of a wide range of applications for high availability. We have improved the performance of OCFS2 in SUSE Linux Enterprise High Availability Extension 12. SUSE Linux Enterprise High Availability Extension includes the latest version of OCFS2, which is now a shared-disk POSIX-compliant generic cluster file system. Using OCFS2, you can now cluster a much wider range of applications for higher availability using cluster-aware POSIX locking. You can also resize your clusters and add new nodes on the fly. Cluster-aware applications will also be able to make use of parallel I/O for higher performance. GFS2 is a shared disk file system for Linux computer clusters. It allows all nodes to have direct concurrent access to the same shared block storage. GFS2 read and write support is included in SUSE Linux Enterprise High Availability Extension 12.
