Orion Platform 2017.3 feature: High Availability (DR)

Last updated: September 13, 2017

This release of SolarWinds Orion Platform supports automated, near-instantaneous failover to a secondary server located on a different subnet for continuous monitoring in the event that a component of your SolarWinds Orion environment fails.  Multi-subnet deployments require the use of a virtual hostname and DNS credentials to update the DNS record automatically when a failover occurs.

This update provides the following key features:

  • Multi-subnet deployments (WAN deployments for disaster recovery) - Install your backup server software on a server that is connected to a separate subnet that can communicate with your primary server. When you set up your HA pool, the software detects that the backup server is on a different subnet and allows you to provide a virtual hostname and DNS information.
  • Virtual hostname support - Use a virtual hostname in either a single-subnet or multi-subnet HA pool deployment. 
  • Supports Microsoft and BIND DNS, and allows you to integrate with your own DNS solution - SolarWinds HA natively supports Microsoft and BIND DNS. However, we provide some guidance and templates so you can deploy our solution with your DNS software.
  • Select a preferred active server - Choose which server will be the active server. If a failover occurs, the software fails back to the preferred active server as soon as it is up.

Supported operating systems

High availability supports the following operating systems:

  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2016

There are no HA-specific requirements beyond the requirements of the installed SolarWinds Orion products.

SolarWinds strongly recommends that each member in an HA pool have similar hardware and software configurations.
