IBM PowerHA SystemMirror for IBM i enterprise edition
The PowerHA SystemMirror for IBM i Enterprise Edition includes all of the capabilities of the Standard Edition and more. The Enterprise Edition package enables you to extend your data center solution across two sites. PowerHA SystemMirror Enterprise Edition includes support for DS8000, SVC and the Storwize family of storage servers with either Metro Mirror or Global Mirror and with 7.1 of PowerHA SystemMirror, the Enterprise Edition also includes support for geomirroring asynchronous mode. Geomirroring synchronous mode support is included with the PowerHA SystemMirror Standard Edition.
Geographic mirroring is the IBM i host based mirroring over IP network solution that enables small clients to set up a geographically dispersed two node PowerHA SystemMirror cluster using either internal or external disk. The geographic mirroring solution can lower your total cost of ownership in comparison to software replication options in both cost of acquisition and operational management costs. The introduction of geomirror async mode support with PowerHA SystemMirror 7.1 enables clients to extend the PowerHA SystemMirror cluster between sites with virtually unlimited distance. We recommend geomirroring to be used for IASPs under 2 TB.
The Enterprise Edition is essential for clients who must protect themselves from site-wide failures or large-scale disasters by mirroring business-critical data across two sites while enabling automated failover to the remote location. This applies to businesses of any size with multiple sites, regional operations or wherever decentralization of data is desired. The Enterprise Edition offers multiple technologies for achieving long distance data mirroring, failover and resynchronization.
For clients wishing to support more complex configurations such as a campus two node cluster with Metro Mirror in combination with a remote third node connected via Global Mirror; IBM offers PowerHA tools for IBM i option. This is a lab services offering that enables a customized configuration to support your DS8000 PowerHA SystemMirror solution environment. The PowerHA tools for IBM i automates virtually all of your HA/DR operations including FlashCopy.
