Cluster middleware IBM Business Partners and available clustering products

In addition to IBM® PowerHA® for i, there are other cluster management products available.

IBM iCluster for i, as well as other products, provide software solutions for replication and cluster management functions. Most of these solutions are based on logical replication. Logical replication uses remote journal or similar technology to transfer object changes to a remote system, where they are applied to the target objects. In addition to PowerHA management solutions, you can purchase other cluster middleware products which use logical replication technology. Those products typically also include a management interface.
