Set up Multi Instance

Lighthouse supports up to 10 secondary instances for each primary Lighthouse instance.

A Lighthouse with multiple instance support requires multiple separate subnets for Lighthouse VPN connections between:

  • each instance and its nodes.

  • the primary and secondary instance Lighthouses.

Note:  Each subnet must not overlap any subnet in use by another Lighthouse instance.

Before you attempt to set up a multiple instance:

  • Start with what will be the primary instance and one or more Lighthouse instances to act as secondary. All instances must have the same version of Lighthouse.

  • Configure the networking information for each instance (hostname, external endpoints, network addresses, REST API port).

  • Configure the time settings of each instance.

  • Ensure you have a subscription active on your primary Lighthouse.

Steps to Setup Multi Instance

To set up multi Instance on the primary Lighthouse:

  1. Ensure that you are on the primary Lighthouse.

  2. In the Settings Pane, select > MULTI INSTANCE > Secondary Lighthouses.
    The SECONDARY LIGHTHOUSES page displays.

  3. Click Add Secondary Lighthouse.
    The ADD SECONDARY LIGHTHOUSE page displays.

  6. Enter the Network Port for HTTPS connections.

  7. Enter the Username.

  8. Enter the Password.

  9. Under VPN NETWORK RANGE, provide the following details:

    • Address Space: enter a valid, unused network subnet to use as the secondary lhvpn address range.

    • CIDR Subnet Mask

    Notes:
    • Lighthouse displays the Calculated Node Capacity based on the values entered reflecting the addressable nodes based on the network.
    • The secondary Lighthouse instance must be able to reach the primary instance on UDP Port 1195.

  10. Under SMART MANAGEMENT FABRIC RANGE, provide the following SMF range details if the secondary lighthouse is to be discoverable on the Smart Management Fabric:

    • Address Space

    • CIDR Subnet Mask

    Note:  Lighthouse displays the Calculated Node Capacity based on the values entered reflecting the addressable nodes based on the network.
