Maxava IBM i HA/DR Technical Insight
The worldwide landscape of High Availability and Disaster Recovery (“HA/DR”) is rapidly changing. Businesses are moving away from traditional tape backup solutions and introducing real-time data replication into their disaster recovery environments. Companies running on the IBM i platform have a plethora of choices to make when evaluating their HA/DR options – Hardware or Software Replication, Conventional or Cloud Based Solutions, and use of the Audit Journal, or a more advanced and less invasive solution? When they do so they are required to make some big decisions on the architecture they will depend on for their future data security and business continuity.
This paper has been written for those organizations that are evaluating their current HA/DR solution options and are looking to improve on their current approach.
It provides a high-level view of what an HA/DR solution offers and some of the fundamental considerations when deciding between hardware and software (logical) replication.
It then reviews in more depth some of the critical factors relating to HA/DR software replication and how Maxava HA has been designed to address them. The most important of these include;
-
Integrity of replication.
-
Reliability.
-
Processing performance.
-
Ease of use.
-
Speed of transfer from production to backup environments. (to avoid backlogs on production causing data loss on a system failure)
