HA architecture across subnets, MPE and APE & SQL AlwaysOn Cluster

davidb35467

I am doing some analysis on the architecture for a new environment, and HA is a requirement.

Currently we have licensing for NCM, SAM, IPAM, NTA, NPM

We also have a license for a additional polling engine (APE)

I know we would need to purchase a license for HA.

Thought it would be worth mentioning:

• Make use of a 2017 SQL AlwaysOn Cluster.
  • SQL cluster will be HA between our two London data centers
• The Main Polling Engine (MPE) will be located in London
• The APE will be located in Vancouver.
  • Reason for the geographically dispersed polling engines is that the majority of our VM's are located in London and Vancouver.
• Make use of Microsoft DNS for the virtual hostname

The questions i have are:

1. In order to introduce HA will i need HA on both the MPE and APE?
   1. e.g. a third server that will act as a secondary server to the MPE and a fourth server that will act as the secondary server to the APE Orwill the APE become the HA pool member?
   2. e.g. two HA licenses / two HA pools (total of 4 Orion servers)

Below are the two options...which one is correct?

Anything i have missed?

Hi davidb35467,

the second solution is the right one.

you find everything to SolarWinds HA solutions under

SolarWinds High Availability - SolarWinds Worldwide, LLC. Help and Support

In your deployment, you need a license for the MPE and one for the APE.

Because of the remote polling engine you have to pay attention to the post here:
