Shared storage clustering
IBM PowerHA enables high availability and disaster recovery solutions based on disk storage pools |
- Storage pools (IASPs) are 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
Switchable or mirrored. IASPs are switchable between primary and secondary nodes in the cluster |
- Simple on demand role swap and fail over operations. Designed for and used by thousands of clients 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® or the DS6000™ with PowerHA for i |
- Simple on demand role swap or fail over operations over unlimited distance. Extend your PowerHA data center experience over an unlimited distance.
|
Geographic Mirroring
Synchronous IBM i host based mirroring between data in IASPs |
- Inexpensive data center mirroring, easy to use, on demand role swap operation, no day to day maintenance.
|
Metro Mirror
Synchronous DS8000 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 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 or DS6000 from your user interface |
- Create “instantaneous” copies of your IASP to use for off-line backups to tape without disrupting your production environment.
