Requirements for Configuring High Availability Pairs
A High Availability (HA) pair requires a very specific hardware configuration, and the two Integration Appliances must meet certain requirements.
To operate as an HA pair, the two Integration Appliances
must meet the following requirements:
- Both Integration Appliances must use the same version of the Cast Iron® Operating System. When you apply a patch to one Integration Appliance, the same patch is automatically applied to the other Integration Appliance in the HA pair.
- The replication interfaces on one machine must be connected by cable to the corresponding interface on the other machine.
- The management network port on each Integration Appliance must be connected to the same subnet.
- The data network port on each Integration Appliance must be connected to the same subnet.
Note: A note regarding High Availability pairs and Hybrid Cloud
Integration (HCI) support – If you are using HCI functionality and
attempt to convert two Integration Appliances to HA, the HCI function
will no longer be supported.
