Summary

IBM PowerHA SystemMirror (formerly known as HACMP – High Availability Cluster Multiprocessing) provides solutions that maintain high availability, while making the IT environment simpler and more flexibile to respond to changing needs. IBM PowerHA SystemMirror in brief:

Simple to manage yet ultra reliable World-class, 24×7 clustering technology with IBM advanced systems technologies Allows for cluster upgrades and system maintenance without interrupting operations Offers multiple recovery and data replication methods Monitors, detects and reacts to hardware and software problems Can be configured to react to hundreds of system events Can move services, users, applications & data to backup systems during scheduled maintenance Simple to configure and flexible to maintain. Key to implement and meet your availability level targets Significantly reduces planned and unplanned outages

IBM PowerHA SystemMirror editions in brief:

• PowerHA SystemMirror Standard Edition provides high availability in implementations where all cluster nodes can access the same disk storage subsystem.
• PowerHA SystemMirror Enterprise Edition provides high availability in implementations where cluster nodes are geographically dispersed.
