High-Availability Examples

The following examples demonstrate different methods of how a standalone T-Server can operate in a high-availability (HA) configuration with redundant CSTA Connectors.

Example 1

This example is similar to the HA warm standby redundant configuration for CSTA Connector, as illustrated below:

Warm-Standby (HA) Redundant Configuration

Example 2

This example illustrates the seamless T-Server switchover in cases where the CSTA Connector fails. A failed CSTA Connector must be restarted to support the next CSTA Connector failover.

T-Server Switchover Where CSTA Connector Fails

Example 3

This example illustrates how the primary and backup T-Servers select the CSTA Connector with the shortest response time:

Primary and Backup T-Server Selection

Example 4

This example illustrates how the primary and backup T-Servers use different sets of CSTA Connectors to select the most responsive one:
