Clustering Considerations

The cluster contains multiple nodes which can be contained in separate firewalled networks.

Network ports need to be opened on firewalls to allow inter-node communication – these are described in more detail in the Platform Guide.

All communication between nodes is encrypted.

Node type	Ports
WebProxy	22 (ssh & sftp), 80 (http), 161 & 162 (snmp), 443 & 8443 (https)
Unified	22 (ssh & sftp), 80 (http), 161 & 162 (snmp), 443 & 8443 (https), 27020 & 27030 (database)

• 22/ssh is used for remote administration

• 80 and 443 is used for the web server

• 161 and 162 are used for sending and receiving snmp

• 8443 is used for inter-cluster communication

• 27020 and 27030 is used for database queries and replication
