What's New in SUSE Linux Enterprise High Availability Extension 11 Service Pack 3
New way of monitoring and improved usability
Service Pack 3 offers new functionality that makes it even easier to manage and monitor the integrated suite of robust, open-source clustering technologies in SUSE Linux Enterprise High Availability Extension. These enhancements help reduce administrative effort and enable less experienced users to install and manage clustering scenarios. The result: it has never been easier to maximize the availability of Linux workloads.
New features and functionality in SUSE Linux Enterprise High Availability Extension 11 Service Pack 3 include:
New, Easier Monitoring
- Blackbox Monitoring—Monitor and manage services without the need to install software on the service side. Now you can monitor resources within virtual machines from the hypervisor and improve protection of VMs as cluster workloads. Guests remain unaltered; monitoring is external. Service Pack 3 can utilize widely available nagios/icinga probes.
Ease of Use
- Better GUI, Better Support—Service Pack 3 now allows configuration changes in the cluster. There are also additional, handy functions in History Explorer, such as clean-up for old reports and linking to the transition log.
- Easier Management—Pacemaker is now upgraded to 1.1.9, supporting maintenance for a single node. It can calculate the default probe timeout and improves handling of group-based utilization. Service Pack 3 also improves management in YaST2 and resource agents.
Additional New Capabilities in SUSE Linux Enterprise High Availability Extension 11 Service Pack 3
- SBD—SUSE extends Quorum/Pacemaker health. By deploying three or more redundant and independent storage systems with SBD devices on each, you can better compensate for the failure of a quorum device and eliminate single points of failure. This feature was partially released in SP2 maintenance and now has more complete support. It now can use multiple SBD devices to make them redundant the same way as storage is redundant available.
What makes SUSE Linux Enterprise High Availability Extension 11 Service Pack 3 even more attractive is its enhanced Geo Clustering. This best-in-class Geo Clustering solution lets you deploy physical and virtual Linux clusters between data centers located anywhere in the world, extending the capabilities of SUSE Linux Enterprise High Availability Extension across unlimited distances. Available for all architectures with an up-to-date stack, it is the best Geo Clustering choice for your mission-critical workloads. More ›
