IBM PowerHA SystemMirror for AIX introduces its next technology level Version 7.1.2 and includes the following key features:
- Version 7.1.2 is available in Standard Edition as well as Enterprise Edition. The Enterprise Edition provides for Disaster Recovery solutions with both host based mirroring and storage-based mirroring.
- IPv6 support is enabled with this version for the Version 7 product.
- HyperSwap capability is introduced. HyperSwap with DS8800 storage subsystem provides for continuous availability against storage failures.
- Support for multisites Disaster Recovery management.
- Enhancements to graphical management interface to deploy and manage single and multisite cluster solutions.
PowerHA SystemMirror for AIX , V7.1 is the next generation of clustering solutions for high availability and disaster recovery. Based on Cluster Aware AIX (CAA), the PowerHA SystemMirror Standard Edition and the PowerHA SystemMirror Enterprise Edition offerings represent a major shift in the traditional architectural concepts of building and managing clusters for high availability and disaster recovery. Cluster Aware AIX shifts key aspects of clustering technology into the AIX kernel, enabling simpler, more robust cluster formation and management. Featuring near real-time internode messaging and synchronization, cluster-wide health management, multichannel redundancy, and multicasting communications (with the Standard Edition), PowerHA SystemMirror V7.1 makes data center operations for high availability simpler and more robust.
The PowerHA SystemMirror V7.1 offering introduces new capabilities that include stretched clusters and linked clusters, both of which enable kernel-level communications between geographically dispersed nodes for more robust configurations. The linked cluster topology has an independent cluster repository at the primary and secondary sites, which enables clients to have two data centers linked by unicasting. A stretched cluster configuration has a single repository and supports multicasting and multichannel communications.
The Version 7 clustering technology enables PowerHA SystemMirror V7.1 Enterprise Edition to support HyperSwap with the IBM System Storage® DS8800 and Metro Mirror replication. HyperSwap technology enables PowerHA Enterprise Edition clients to deploy two sites and two DS8800 storage units between sites in a cross-coupled configuration that provides production continuity through a storage failure.
In addition to integration with Cluster Aware AIX , PowerHA SystemMirror V7.1 Standard Edition features include:
- Centralized cluster repository for cluster-wide name space management and internode synchronization.
- PowerHA SystemMirror kernel-based low-latency event communication.
- Smart Assist technology, enabling out-of-the-box high availability (HA) support for popular applications, and a new intuitive user interface. The Smart Assist portfolio supports IBM DB2® , IBM WebSphere® , IBM 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 SAP liveCache Hot Standby Solution.
- IPv6 is supported for both internal and external cluster communications.
- The IBM Systems Director based PowerHA SystemMirror management interface provides for an easy-to-use graphical interface to deploy and manage the PowerHA SystemMirror clusters. A set of wizards guides customers through creation of cluster and resource groups. A sophisticated management interface allows the customer to manage various clusters in their environment. Using this interface, administrators can generate reports, examine topology, and be notified of status changes to resources and clusters.
- PowerHA SystemMirror 7.1 Standard Edition and Enterprise Edition include the IBM Systems Director plugin at no charge, which can be installed and used by the customer to deploy and manage PowerHA SystemMirror clusters. The plugin consists of the IBM Systems Director server component and also the agent that gets deployed on individual nodes in the PowerHA SystemMirror clusters. The IBM Systems Director Server component of the PowerHA plugin can also be downloaded and installed by the customer.
PowerHA SystemMirror for AIX 7.1 highlights include:
- PowerHA SystemMirror V7.1 Enterprise Edition.
- Support for HyperSwap with the DS8800.
- Linked cluster technology for multisite unicast communications with independent cluster repositories.
- Stretched cluster technology for multisite multicast communications with a shared cluster repository.
- PowerHA SystemMirror enables key storage, network, and security capabilities of the stretched cluster and linked cluster topologies to be centrally administered. The IBM Systems Director based graphical interface provides for a sophisticated dashboard for managing all the clusters in the enterprise environment from a single interface.
- Multisite install wizard for simplified setup of the PowerHA multisite cluster.
The PowerHA SystemMirror 7.1 Enterprise Edition also supports:
- IBM Storage Systems DS8800, SVC, V7000, and XIV with either Metro Mirror or Global Mirror, enabling automatic failover between geographically dispersed data centers.
PowerHA® SystemMirror® for AIX® Standard Edition is the IBM® Power Systems™ data center solution that helps protect critical business applications from outages, planned or unplanned.
PowerHA SystemMirror for AIX Enterprise Edition includes the Standard Edition plus advanced capabilities such as failover to back up resources at remote locations.
New with this release, Enterprise Edition supports:
- Metro Mirror/Global Mirror in DS8700 and DS8800 configurations
- HyperSwap® in a Metro Mirror with DS8800 configuration
- Global Mirror/Metro in an SVC or V7000 configuration
- Global Mirror/Metro Mirror in an XIV® configuration
- GLVM sync and async mode
Either edition when deployed in dynamic logical partitioning (DLPAR) environments enables managed utilization of resources on a secondary node in the PowerHA SystemMirror cluster for IBM POWER5 and later processors.
