IBM PowerHA SystemMirror for AIX

PowerHA SystemMirror V7 for AIX

PowerHA SystemMirror V7 integrates clustering technology into the kernel and the OS, enabling our customers to be more productive while delivering high quality IT services with robust and easy-to-manage solutions.

The IBM PowerHA for AIX standard edition features cluster aware AIX, which provides a strategic foundation for Power Systems™ software. It enables kernel level messaging, event management, and monitoring in coordination with AIX. PowerHA 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 monitoring and event management functioning at the kernel of the operating system (OS), the cluster is not prone to job scheduling issues or other OS related operations.

PowerHA V7.2 is focused on providing superior economic value, greater automation and more robust clustering technology. PowerHA V7.2 integrates and manages Power enterprise pools and elastic Capacity on Demand as part of failover operations enabling the automated move of processor, memory and software entitlements between partitions in the cluster. Live partition mobility (LPM) and AIX live update are integrated as part of a PowerHA V7.2 cluster. In both cases, these operations will maintain the cluster topology through the transition and exchange of nodes as they are removed and replaced due to an LPM or AIX live update procedure. Cluster integrity is significantly enhanced in V7.2 with failing node quarantine policies which ensure that an intermittent or failing node is isolated prior to a failover operation—thereby eliminating the possibility of partitioned cluster caused by the sick node returning during the failover process.

PowerHA V7 provides smart assists for easier, out-of-the-box high availability 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 helps define the high availability policy and provides periodic health monitoring, enabling middleware and resource dependencies to be restarted via the specified policy. With PowerHA V7, the smart assist portfolio supports DB2®, WebSphere®, MQSeries®, Oracle, SAP, SAP MaxDB, Enterprise Content Manager, Tivoli™ Storage 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.
