IBM i HA High Availability Software Replication
IBM i HA High Availability software eliminates downtime using real-time no lock synchronization, prevents data loss, enables quick role swaps, includes transaction integrity checking using local journaling, allows two-way replication, supports mixed IBM i OS versions and hardware configurations, and has built-in compression and encryption. The IBM i HA software is quick to setup real-time replication, has the most features available out of the box for a high availability solution, allowing customizable switch procedures that can be managed by a graphical interface or the green screen. IBM i HA uses synchronous replication built on IBM i local journaling to ensure data integrity.
Production and target HA systems can be on a different OS400 version and release, have different hardware configurations as well as different storage (internal, external, and SSD). The IBM i HA replication can be across the globe in a one-to-one, one-to-many, many-to-one, bi-directional, daisy-chain, broadcast or LPAR-to-LPAR configurations, and can expand to multi-node environments. IBM i system replication supports any combination of on-premises, hosted, in the cloud or hybrid, and allow both SYSBAS and iASP.
Replicated data on the backup server is validated to ensure it remains in sync with the production server through scheduled audits, on-demand audits and continuous monitoring. Out-of-sync conditions are automatically and efficiently repaired without being placed on hold.
The IBM i HA software includes both a 5250 and graphical user interface to monitor and manage replication, and provides support for seven languages in the GUI. Alerts can be configured for email, MSGQ and SNMP, with a plug-in for Nagios. In the event of a planned or unplanned outage, customizable, built-in switch procedures can be run step-by-step, interactively or in batch mode. Tools are also shipped with Quick-EDD/HA to support functions such as analysis, monitoring, and specific configuration scenarios.

Reasons to consider High Availability solution instead of a Disaster Recovery solution
- Your recovery time objective is minutes, not hours.
- Two-way replication is needed (when target system becomes production, and target needs to replicate changes to original production).
- You realize planned down time costs the company more money than unplanned downtime.
- Replication to and from switchable IASP.
- Role Swaps to and from multiple systems
- Installation, configuration and training
- Various levels of managed services, includes annual role swap testing
- Role swap preparation and testing
- Unplanned role swap assistance
- Adjustments and optimization
- Software upgrades, fixes and service packs
