Are there any plans to allow more than 2 members in an HA pool? Specifically for the main poller?
Let me explain:
We have a customer requirement to account for a multi site outage.
They currently have 3 sites of which there is a Solarwinds poller at each site.
Each site has an HA standby member in the opposite site.
We have tested the below scenaio forwards and backwards and it works very well:
Site A:
Main Poller Active (Site A)
APE Poller Standby (For Site B)
APE Poller Standby (For Site C)
SQL Always On DB
Site B:
Main Poller Standby (For site A)
APE Poller Active (For Site B)
SQL Always ON DB Standby
Site C:
APE Poller Active (For Site C)
However you can see where the gap lies at Site C. If both Site A and B go dark, it is my understanding that the APE will continue to collect data for a short amount of time but obviously won't be able to for very long nor send out any alerting. So short of deploying a separate solarwinds instance and DB at each site, it would just be so much easier to extend the SQL always on DR replication to site C as well as have a standby main poller in site C to take over alerting in the event of a multi site failure.
Or can anyone else offer up any architecture advice? I thought about an additional web console, etc but I think that requires the main poller to be functional.
