Cluster Configuration
A CC-SG cluster uses two CC-SG nodes, one Primary node and one Secondary node, for backup
security in case of Primary CC-SG node failure. Both nodes share common data for active users
and active connections, and all status data is replicated between the two nodes. The primary and
secondary nodes in a cluster must be running the same version of software. Unless defined by the
user, CC-SG will assign a default name to each cluster node.
Devices in a CC-SG cluster must be aware of the IP of the Primary CC-SG node in order to be
able to notify the Primary node of status change events. If the Primary node fails, the Secondary
node immediately assumes all Primary node functionality. This requires initialization of the CC-
SG application and user sessions and all existing sessions originating on the Primary CC-SG node
will terminate. The devices connected to the Primary CC-SG unit will recognize that the Primary
node is not responding and will respond to requests initiated by the Secondary node.
Note: In a cluster configuration, only the Primary CC-SG communicates with CC-NOC.
Whenever a CC-SG becomes primary, it sends its IP address, in addition to the IP address of the
Secondary CC-SG, to CC- NOC.
