iSeries HA High Availability AS400 Software

iSeries HA high availability software for AS400 systems provides real-time two way replication of a production system to one or more recovery systems that is local, remote or in the cloud, for complete data protection against both planned and unplanned downtime events. A IBM i high availability solution that will protect your data and keep your business running regardless of the situation. Using IBM i HA software in an unplanned production outage, operations will continue on the failover system without data loss and minimal downtime. iSeries HA provides a higher level of protection than iSeries DR software, but less than Continuous Availability offerings. IBM i High availability software is for companies that can only afford minutes of downtime and require critical iSeries applications available and access to data 24/7/365. In addition to unplanned downtime events, iSeries HA will also eliminate downtime caused by backups, upgrades, maintenance tasks, new applications, testing and other events that routinely interrupt production systems.

A key strength of high availability solutions is its decades of experience and utilization of IBM OS400 remote journaling. It very efficiently gets all data changes from production (including those not covered by remote journaling, such as database files, data areas, data queues and IFS objects), into a buffer on the recovery system. Multiple apply paths are used to apply the changes on the recovery iSeries. OS400 journaling enables a near zero “seconds” Recovery Point Objective (RPO), even when the apply process must be halted to allow other operations against the backup copy to be completed. For instance, in the event of maintenance tasks such as a backup, producton pushes changes to a buffer on the recovery system when the apply process is halted and makes data on the backup servers available for read only operations.

Some common 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)
• Planned down time events costs the company to much money
• Replication to and from a switchable IASP
• Role Swaps to and from multiple systems

Optional Services

• 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

Disaster Recovery System Requirements:

• OS400 V6R1 or higher (production and target systems can be at different version/release levels)
