Synology High Availability Wizard

This wizard guides you through the process of creating and setting up a high-availability cluster.

To launch this wizard:

  1. Open Synology High Availability.
  2. Go to the Overview page.
  3. Click Create HA cluster.

Note:

To set up the passive server:

Please designate a Synology server to be the passive server. Under normal conditions, the passive server does not provide services. However, in the event of a malfunction, services can be transferred from the active server to the passive server.

  1. IP address: Please enter the passive server IP address.
  2. Username: Provide a user account belonging to the administrator group on the destination server.
  3. Password: Provide the password for the account belonging to the administrator group.

Note:

To configure the heartbeat connection:

Connect the two servers to each other. This connection shall serve as the "Heartbeat" connection between the two servers, facilitating communication and allowing data to be replicated from the active server to the passive server. This connection must meet the following criteria:

After confirming the above, go to the HA Connection (Heartbeat) Interface section and choose the network interface on the servers to serve as the Heartbeat connection.

Note:

Configuring Link Aggregation on the Heartbeat or data connections:

To configure the network interface settings of the high-availability cluster:

The high-availability cluster will use a high-availability cluster IP address as its connection interface to the outside. You can connect using this high-availability cluster IP address when you wish to use DSM services regardless of which Synology server is the active server. This prevents from having to connect to different IP addresses after performing a switchover from the active server to the passive server.

  1. Cluster Server Name: The name of the high-availability cluster. Please refer to server naming rules for information regarding name restrictions.
  2. Network Interface: The network interface to be used by the high-availability cluster. You must choose a different LAN port from the one designated for data-replication in the previous step.
  3. IP Address: The IP address to be used by the high-availability cluster. Regardless of which server is actively providing services, the cluster can be connected to via this IP.
  4. Subnet Mask: The subnet mask to be used by the high-availability cluster.

Assigning a VLAN ID for the data connection:

To confirm settings:

Please double-check the settings to be used by the high-availability cluster. The system will begin binding the high-availability cluster together once you click Apply.
