An active/passive deployment of IBM Integration Bus
The below diagram gives an overview of an active/passive environment.

You can see that there is a file system shared between the two systems, and the same Integration node is able to run on either system.

Active/passive HA failover solutions
In IBM Integration Bus the whole Integration Node fails over as a unit. All Integration Servers owned by that Integration Node, as well as the MQ Messaging runtime (queue manager) fail over together.

There are two technology options for enabling HA failover of an Integration Node as follows:

1. Use the built-in multi-instance feature of IBM Integration Bus

Requires a highly available network-attached filesystem, such as IBM GPFS or a highly available NFSv4 file server.

See this TechNote for details of filesystem requirements.

2. Use a HA Clustering technology, such as IBM PowerHA (formerly HACMP), Microsoft Cluster Server or Veritas Cluster Server

These technologies allows use of fibre-attached SAN or shared-SCSI storage.

  1. Active-Active or active-passive setup is better for IIB
