High Availability is provided for SolarWinds products released on Orion Platform version 2016.2 and later. You cannot enable an HA pool for a server that includes non-supported products.
Visit SolarWinds KB MT6886 to build an upgrade path.
The following products can be integrated with your Orion Platform-based product. The integration module between products is supported under SolarWinds High Availability, but the stand-alone product is not supported.
SolarWinds strongly recommends that the hardware and software of the standby server matches the primary server. Using matching system specifications and installed software ensures the same performance in the event of a failover.
|4369||TCP||RabbitMQ||bidirectional||TCP ports 4369 and 25672 must be open between the main and secondary servers to allow RabbitMQ clustering between the two servers. These ports exchange EPMD and Erlang distribution protocol messages for RabbbitMQ. They do not need to be open in additional polling engine pools.|

|bidirectional||Port 5671 must be open into the HA pool with the main Orion server from all Orion servers.|
|25672||TCP||RabbitMQ||bidirectional||TCP ports 4369 and 25672 must be open between the main and secondary servers to allow RabbitMQ clustering between the two servers. These ports exchange EPMD and Erlang distribution protocol messages for RabbbitMQ. They do not need to be open in additional polling engine pools.|
SolarWinds High Availability does not support IPv6 addresses.
You may need to modify firewall rules to allow traffic from pool members and to the VIP address. For example, you may need to modify the NetFlow firewall rules to allow incoming TCP traffic on port 2055 to go to the VIP address.
Depending on your network, you may have additional requirements. Up to three IP addresses per pool may be in use among the VIP, primary, and secondary servers because of how Windows calculates the source IP address from the HA pool. You can modify your devices to receive requests from all IP addresses or determine which IP address is used as the source IP address.
