Feature	Benefits
Shared (active/passive) storage clustering IBM PowerHA enables high availability and disaster recovery solutions based on disk storage pools	Storage pools (IASPs) are switched or mirrored real time between systems in a cluster. With no out-of-sync conditions and no lag time on the backup system, you’re ready to role swap on demand.
High Availability IASPs are switched and/or mirrored between primary and secondary nodes in the cluster	Simple on-demand role swap and failover operations. Designed for and used by clients worldwide to deploy trouble free HA operations.
Disaster Recovery All data in a storage pool can be mirrored over unlimited distance using Global Mirror and the DS8000, SVC or the Storwize V7000 with PowerHA for i	Simple on demand role swap or failover operations over unlimited distance. Extend your PowerHA data center experience over an unlimited distance.
Geographic Mirroring IBM i host-based mirroring between data in IASPs	Inexpensive easy-to-use, on-demand role swap operation, no day-to-day maintenance.
Metro Mirror Synchronous DS8000, SVC or V7000 hosted mirroring for your PowerHA cluster	Storage based Mirroring means that even if the system in your cluster is down, the mirroring between storage servers keeps on going, thus no exposure to a secondary outage and no resync operations after the down system is brought back into the HA cluster.
Global Mirror Asynchronous DS8000, SVC or V7000 hosted Mirroring for your PowerHA disaster recovery cluster	Extend your PowerHA data center solution to unlimited distances with the same basic characteristics of hands-off operations and on-demand role swap operations.
Flash copy PowerHA i also allows you to simply and quickly conduct flash copy operations on your DS8000, SVC or V7000 from your user interface	Create “instantaneous” copies of your IASP to use for offline backups to tape without disrupting your production environment.
