Network
This page contains two tabs, one displays the network settings of the high-availability cluster and the other the hosts.
HA Cluster
General
The hostname of the cluster is shown here. Note that the hostname must be different from either of the two hosts.
Network
All network connections, regardless used or un-used, are displayed in this field.
- Cluster interface: at least one cluster interface is displayed. Additional interfaces can be manually added by clicking the Manage network interface button.
- Heartbeat interface: this is only one Heartbeat connection allowed in the cluster.
When creating a high-availability cluster, the system generates a common IP address for the high-availability cluster IP to receive incoming connections. Additional high-availability cluster IP addresses can be created if necessary. The IP addresses of activated network interfaces on the active server will be displayed in this field. The Heartbeat connection is also displayed. This tab shows the below information:
- Interface: The network interface(s) on the active server.
- Speed: The speed of the interface.
- IP address: When creating a high-availability cluster, the system generates a common IP address for the high-availability cluster IP to receive incoming connections. You can connect to the high-availability cluster using this IP address when you wish to log into DiskStation Manager (DSM), regardless of which Synology server is the active server. This prevents from having to connect to different IP addresses after a switchover occurs.
- Connection: Displays whether this interface is connected or not.
- Details: The role of the interface (Cluster or Heartbeat)
Hosts
This tab shows the status of network interfaces on the active and the passive server. Of these, the Heartbeat connection will occupy one network interface on each of the active and passive servers. These tabs display the following information:
- Network Interface: The physical network interface on the server.
- Connection: Displays whether this interface is connected or not.
- Details: The role of the interface (Cluster or Heartbeat)
