IBM PowerHA SystemMirror for i

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 V7000 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/medium 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.

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.

• The Enterprise Edition with the included geographic mirroring option provides asynchronous data mirroring and failover to remote sites. Users deployed with the Standard Edition can readily expand capabilities with the Enterprise Edition to deploy a highly resilient geographically dispersed environment.
• The Enterprise Edition supports Metro Mirror and Global Mirror with the DS8000®, the SAN Volume Controller (SVC) and the Storwize® V7000 IBM Storage Servers, enabling automatic failover or planned switchover for semi-annual compliance testing. By automating the management of Metro Mirror or Global Mirror, recovery time is minimized after an outage, regardless of whether the clustered environment is local or geographically dispersed. The Enterprise Edition, in combination with Metro Mirror or Global Mirror, manages a clustered environment to allow mirroring of critical data to be maintained at all times. And let’s not forget about FlashCopy® which whether used with either the Standard Edition or the Enterprise Edition enables you to create a point in time copy with almost no disruption to your production environment; that save window issue is gone. You can now backup to tape at your convenience.

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 the Advanced Copy Services for PowerHA option. This is a lab services offering that enables a customized configuration to support your DS8000 PowerHA SystemMirror solution environment. The Advanced Copy Services for PowerHA automates virtually all of your HA/DR operations including Flash Copy.
