What's New in SUSE Linux Enterprise High Availability Extension 11 SP2
Now even less-experienced administrators can easily install and manage clustering scenarios.
Service Pack 2 offers new functionality that makes it even easier to set up and use the integrated suite of robust, open-source clustering technologies in SUSE Linux Enterprise High Availability Extension. These enhancements help reduce administrator effort and enable less experienced users to install and manage clustering scenarios. It has never been easier to maximize the availability of Linux workloads.
New features and functionality in SUSE Linux Enterprise High Availability Extension 11 SP2 include:
Easy Set-up and Installation
- Templates and Wizards—Administrators who lack in-depth knowledge of Linux clustering can use the simple wizards and templates included in SUSE Linux Enterprise High Availability Extension to quickly complete basic set-up tasks. These tools can also be used to configure and add standard workloads. Using the product's flexible UI, customers and third-parties can build their own wizards to speed the execution of routine tasks.
- Cluster Bootstrap—The Cluster Bootstrap offers a menu driven set-up process for rapidly deploying a base cluster.
- Cluster Join—Cluster Join enables effortless cluster set-up and expansion of existing clusters. Once a node or cluster is built, new nodes can be added without the need to manually replicate configurations.
- Access Control Lists—Access Control Lists align cluster management with organizations' processes and policies. By applying role-based controls, you can ensure that only those members of your IT staff with the proper authority can access the cluster management tools. Restricting cluster management access not only helps to maintain security, but also improves cluster reliability by limiting mistakes.
- Web Console—With Service Pack 2, the Web Console supports full cluster administration, such as adding resources, constraints, and dependencies. The Web Console also provides the management of groups of resources, which improves scalability on clusters with more than 100 resources. Additionally, you can access control lists, the cluster test drive, and a new graphical history explorer through the Web Console.
- Cluster Wide Shell—The Cluster Wide Shell improves the effectiveness of managing cluster nodes by enabling the execution of commands across all nodes using the PSSH command.
- History Explorer—This web-based support tool allows interactive access to cluster logs. It displays and analyzes actions taken by SUSE Linux Enterprise High Availability Extension. The History Explorer delivers a more intuitive experience for users who are unfamiliar with the command line.
- Log File Query Tools—Working together with the History Explorer, these centralized support tools find and analyze the log files for all cluster nodes in a single instance. The resulting report provides an administrator or SUSE technical support with the necessary information to promptly diagnose and resolve cluster issues.
Additional New Capabilities in SUSE Linux Enterprise High Availability Extension 11 SP2
- Connection Tracking for Load Balancing—In the event the load balancer failsover to a backup load balancer, the client and backend server remain connected without the need to restart sessions or applications. Configuring load balancing with connection tracking ensures the immediate availability of data, which increases overall throughput and increases reliability during failover.
- Join Clustered SAMBA with Active Directory Automatically—Service Pack 2 enhances the interoperability of SUSE's high availability stack with Microsoft environments. By providing for the automatic integration of Clustered SAMBA resources and SAMBA configuration changes into Active Directory, you can better manage mixed environments.
- Reliable Storage-Based Fencing with Multiple SBD Devices—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.
