Operations configuration of HULFT with the clustering function
The operations configuration of failover clustering systems can be classified to unidirectional standby configurations and bidirectional standby configurations. The HULFT Clustering function can operate in both configurations.
Unidirectional Standby Configuration (ACTIVE-STANDBY Configuration)
In this configuration, one server operates as the ACTIVE system that carries out processing and the other server operates as the STANDBY system that does not carry out processing.
Figure 1.2 HULFT in Unidirectional Standby Configuration
Bidirectional Standby Configuration (ACTIVE-ACTIVE Configuration)
In this configuration, multiple servers carry out processing and function as the STANDBY system for each other.
