Interface failover configuration approaches

There are two approaches to configuring interface failover: synchronization through the data source (phase 1 failover), and synchronization through a shared file (phase 2 failover). Phase 1 failover is now deprecated and is not recommended. This guide tells you how to configure phase 2 failover.

Shared-file synchronization (phase 2 failover)

With shared-file synchronization, UniInt Failover writes information to a shared file to communicate status and to synchronize operations between two interfaces. With this method, UniInt Failover can provide hot, warm, or cold failover. With hot failover, no data loss occurs when an interface fails. With warm or cold failover, however, some data loss might occur when an interface fails.

You must choose a location for the shared file. We recommend the following best practices:

• Store the shared file on a file-server computer that has no other role in the data-collection process. Do not store the file on the Data Archive server or interface computers.

• Exclude the location of the shared file from virus scanning.
