IBM PowerHA SystemMirror for AIX

PowerHA SystemMirror for AIX Enterprise Edition

The PowerHA SystemMirror 6.1 Enterprise Edition package enables you to extend your data center solution across multiple sites and with 6.1.7 of PowerHA SystemMirror, the Enterprise Edition expands HA/DR support to include the Storwize v7000 and XIV for two-site PowerHA Enterprise Edition capability.

Increasingly, IT organizations are being asked to demonstrate their disaster recovery operational capability. In the past this was typically a recover from tape operation or a reboot operation at the remote location. The PowerHA SystemMirror Enterprise Edition is essential for clients who must both protect themselves from site-wide failures as well as to be able to readily demonstrate the capability to do so. Storage servers provide the data replication services and the Enterprise Edition enables automation of the failover process. The Enterprise Edition supports multiple technologies for achieving long distance data mirroring, failover and resynchronization.

• The Enterprise Edition with the GLVM (Geographic Logical Volume Manager) component provides host-based synchronous and asynchronous data replication 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. You can economically deploy your own in-house disaster recovery solution with the GLVM configuration wizard. Note that GLVM data replication is not dependent on the storage subsystem capabilities and hence is suitable for storage that is not capable of replicating on its own.
• The Enterprise Edition supports IBM Storage Systems DS8800, SVC, Storwize v7000 and XIV with either Metro Mirror or Global Mirror, enabling automatic failover between geographically dispersed data centers. By automating the management of 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 Global Mirror or Metro Mirror, manages a clustered environment to allow mirroring of critical data to be maintained at all times.
• The PowerHA SystemMirror 6.1 Enterprise Edition also supports EMC SRDF and Hitachi TrueCopy for high availability and disaster recovery operations. Customers can use the PowerHA SystemMirror SMIT interfaces to specify and manage EMC SRDF, Hitachi Truecopy or HP StorageWorks P9500volumes as part of the failover operations and PowerHA SystemMirror uses the SRDF and Truecopy interfaces to discover and manage the replication as part of the HA management solution.

PowerHA SystemMirror also provides integrated support with campus level failover for Enterprise Storage Server® (ESS), IBM System Storage® (DS6000™ and DS8000®), and SAN Volume Controller (SVC) Metro-Mirror peers and failover for IP-connected peers using the native synchronous mode LVM AIX mirroring technology (campus level hyper swap). When PowerHA SystemMirror detects a failure, it can quickly and automatically take action to restore the application, restarting it on a remote redundant system.
