IBM PowerHA SystemMirror for AIX

PowerHA SystemMirror V7 for AIX

PowerHA SystemMirror V7 represents the next generation of solutions for high availability and disaster recovery. This offering integrates core clustering technology into the kernel and the OS, enabling our customers to be more productive and deliver higher quality IT services while enjoying a more robust and easier-to-manage clustering environment.

The IBM PowerHA SystemMirror for AIX Standard Edition features Cluster Aware AIX, which provides the strategic foundation for Power Systems Software. It enables PowerHA to do kernel level messaging, event management, and monitoring in coordination with AIX. PowerHA features a Director-based management interface, a set of Smart Assists and a number of other enhancements that will make the solution more robust and self managing.

PowerHA SystemMirror monitors numerous soft and hard errors within the cluster from various event sources, including problems that are severe enough to immobilize the system (such as a process failure or exhaustion of system resources). With PowerHA V7, monitoring and event management have been moved into the kernel of the operating system (OS), which provides a robust foundation not prone to job scheduling issues or other events related to OS operations. Cluster awareness enables operating-system-based functions to operate harmoniously with PowerHA. PowerHA SystemMirror is integrated with cluster-aware AIX and exploits the operating system features by extending them across the cluster, enabling efficient centralized management.

The PowerHA V7 graphical interface makes cluster management simpler and more productive by providing a secure, centralized point of operations. An administrator can readily deploy clusters and resource groups using the associated wizard. It provides live updates by graphically displaying the status of resource groups, nodes, sites, and clusters. With a single view you can see the health of the entire enterprise at a glance. With the V7 Enterprise Edition; geographically dispersed PowerHA SystemMirror clusters. You can use your Director based graphical user interface to deploy, monitor and manage your enterprise across multiple data centers.

PowerHA SystemMirror V7 provides Smart Assists for easier, out-of-the-box HA setup and application management for many well-known middleware products. The smart assists are high-availability agents for application deployment and management. Smart Assists are used to define high-availability policies and also to discover software that is deployed within the cluster. Discovery-based information aids in defining the high-availability policy and provides periodic health monitoring, enabling middleware and resource dependencies to be restarted via the specified policy. With PowerHA SystemMirror V7 the Smart Assist portfolio supports DB2®, WebSphere®, MQSeries, Oracle, SAP, SAP MaxDB, Enterprise Content Manager, TSM, Lotus® Domino® Server, IBM LDAP, IBM HTTP printers, and FileNet. PowerHA SystemMirror also includes Smart Assists to deploy and manage the LiveCache and Netweaver environments.
