Back=right mouse click.
The IWSVA High Availability (HA) solution currently supports active/passive pairs utilizing the Transparent Bridge mode. To deploy an IWSVA cluster, each IWSVA unit must use a separate management interface. The Transparent Bridge Mode - High Availability for HA deployment requires at least the four following network interfaces for cluster deployment:
Two for bridge data interfaces
One for the HA interface
One for the separate management interface
Note: IWSVA only supports two HA nodes in a single HA cluster.
Using the Deployment Wizard, you can either:
Create a New Cluster
Join an Existing Cluster
