HA requirements

Table of contents

Updated: 3-9-2017

High Availability is provided for SolarWinds products released on Orion Platform products 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.

Supported products include:

  • Network Performance Monitor 12.0.1 and later
  • Server & Application Monitor 6.3 and later
  • NetFlow Traffic Analyzer 4.2.1 and later
  • Network Configuration Manager 7.5.1 and later
  • IP Address Manager 4.3.2 and later
  • User Device Tracker 3.2.4 and later
  • VoIP & Network Quality Manager 4.2.4 and later
  • Storage Resource Monitor 6.3 and later
  • Web Performance Monitor 2.2.1 and later

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.

  • Storage Manager 6.2.3
  • Virtualization Manager 6.3.2 and later
  • Firewall Security Manager 6.6.8
  • Engineers Toolset 11.0.3 and later
  • Database Performance Analyzer on Orion 10.2 and later
  • Patch Manager 2.1.3 and later

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.

  • Both servers must be installed on Windows Server 2008 R2 or later.
  • Both servers must also meet or closely match the minimum hardware and software requirements for the products you have installed on the primary server.
  • Both servers must be able to connect to your SolarWinds Orion database.
  • If protecting an NTA environment, both servers must be able to connect to the separate NTA Flow Storage database.
  • SolarWinds does not provide failover support for any database.
  • Some SNMP trap, syslog message, and flow data is lost while waiting for the secondary server to become active.

Networking requirements

SolarWinds High Availability does not support IPv6 addresses.

  • Both your primary and secondary servers must be on the same subnet.
  • Both pool members must have static IPv4 addresses set on the network adapter. You do not need dedicated NICs.
  • All pool members must be able to resolve the host names of all additional pollers, additional websites, and the main Orion server. Pool members must also be able to resolve the host names of members in the same pool.
  • A virtual IP address must be available on the same subnet as the primary and secondary servers.
  • Port 5671 must be open between both pool members.
  • TCP ports 4369 and 25672 must be open between the main and secondary server. They do not have to be open in additional polling engine pools.
  • Devices must be able to accept inbound connections from the source IP and VIP addresses.
  • Devices sending syslogs, SNMP traps, and NetFlow information to your Orion server must be configured to send the information to the VIP address and receive requests from the pool.

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.
