PowerHA SystemMirror for AIX 7 represents a new generation of clustering solutions for high availability and disaster recover. 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, helping to enable simpler, more robust cluster formation and management. Cluster Aware AIX features near real-time inter-node messaging and synchronization, cluster-wide health management, and multichannel redundancy. With Technology level (TL) 3, Standard Edition can be configured with unicast (Default option) or multicast communications.

The PowerHA SystemMirror V7.1 offering introduced 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 as well as unicast communications with TL 3.

The version 7 clustering technology enables PowerHA SystemMirror V7.1 Enterprise Edition to support HyperSwap with the IBM System Storage® DS8800 or DS8870 and Metro Mirror replication. HyperSwap technology enables PowerHA Enterprise Edition clients to deploy two Power Systems servers and two DS8870 storage units between sites in a cross-coupled configuration that provides continuity through a storage failure. With this announcement, version 7.1 TL3 enables an active-active HyperSwap configuration that will support active-active workloads on both sites. Active-active site configuration can provide for a powerful deployment model where the loss of compute nodes, storage systems, or even the site, may not result in any disruption to the business as in the traditional failover-based HA model. PowerHA SystemMirror V7.1.3 also will support HyperSwap configuration for a single server. This enables a client to have redundant and geographically dispersed storage servers in a HyperSwap configuration. HyperSwap technology allows nondisruptive switching between storage servers.

In addition to integration with Cluster Aware AIX , PowerHA SystemMirror V7.1 Standard Edition features include:
