The objective behind implementing a high availability solution is to provide near-continuous application availability through both planned and unplanned outages. Business-critical applications are configured into a cluster which is dedicated to keeping production continuously available. In addition to the day-to-day high availability operations, disaster recovery operations are increasingly becoming a standard part of the clustering environment. Once relegated to manual procedures, many industries and companies require periodic testing designed to prove disaster recovery capability. The IBM PowerHA enterprise edition cluster is designed to simplify operations both within the data center and across geographically dispersed locations.
PowerHA SystemMirror Standard Edition and PowerHA SystemMirror Enterprise Edition with Cluster Aware AIX (CAA), are designed to provide robust HA/DR environments focused on ease of implementation and ease of use.
Here are five things to know about PowerHA SystemMirror:
- Delivers a new graphical user interface (with V7.2.1) enabling at a glance monitoring of a cluster or a group of clusters.
The new user interface (UI) available with PowerHA V7.2.1 was designed with continuous and iterative feedback from corporate customers. The new UI/ dashboard enables IT operators to monitor a cluster or a group of clusters with a single view for immediate health status. It also provides intelligent filtering of event logs for more efficient analysis.

- Provides two editions: Standard and Enterprise.
The PowerHA V7 Enterprise Edition enables clients to readily extend their traditional data center cluster to incorporate a remote location environment for disaster recovery. The V7 cluster makes disaster recovery testing relatively simple while putting the operator in charge of managing failover policy and procedures.
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.
- Smart assists streamline implementation and configuration.
A set of high availability agents, called smart assists, are bundled with the PowerHA SystemMirror standard edition to help discover and define high availability policies for most common middleware products.
- Integrates the new generation of servers.
The PowerHA SystemMirror solution runs under the AIX and IBM i operating systems on IBM Power Systems. Through innovative technology, virtual servers, broad support of open standards for application flexibility and a full range of tools to manage IT infrastructure, these servers offer the performance, availability, scalability and infrastructure management demanded by today’s growing, on-demand business environments. They combine the benefits of IBM Power Architecture technology and mainframe-inspired Reliability, Availability, and Serviceability (RAS) features with the OS for efficient handling of mission-critical applications.
- Delivers a proven high availability solution.
High availability solutions from IBM provide clients the confidence that comes from integrated design and testing. This reduces the risk of failures resulting from combining disparate components from multiple vendors and can be a critical factor for business environments. IBM high availability solutions provide the advantage of IBM Power Systems, the AIX or IBM i operating systems, IBM TotalStorage Proven offerings and PowerHA SystemMirror software.
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.
