High Availability for IBM i

HA4i is a premier High Availability solution for the IBM i and its predecessors (AS/400, iSeries, i5 etc) using the latest technology to provide a high performance replication environment. It allows simple, fast and effective role-swaps between instances with the minimum of disruption.


The perception in the market is High Availability is an expensive and complex solution to implement. In the past this might have been true, however many things have changed recently such as reduction in hardware and software licensing to a level where it is now more affordable. Add to this our intuitive approach to managing and configuring the solution and you will find significant reductions in the total cost of ownership over other products in the market.

What's new!

  • The latest release of HA4i brings the ability to replication between multiple nodes (HA4i Multi-Node) providing the option of keeping multiple copies of the data and objects in synch. This allows the product to provide a High Availability instance for fast switching plus a Disaster Recovery instance for infrastructure failure protection. The ability to replicate at the environment (application level) allows both systems to participate in a production environment providing a better utilization of your IBM i resources.
  • New sensing technology provides a continuous monitor for problems which require attention, any issues are fixed where appropriate and notifications sent by the built-in email capabilities.
  • New audit capabilites provide a cleaner and simpler way to continuously audit the replication processes with fewer commands.
  • Improved program packaging and code paths have provided significant performance improvements plus reduced the overall foot print for the product install.
