Active-Active" mode HA setup across different locations.

L0 Member

Hi Team,

 

Greetings,

 We have a requirement like client want to know about the FW HA across different location in "Active-Active" mode.

For example, PA Model: PA-3430

What are requirements for having fw cluster spread across different GEO locations (latency, delay, etc)? Distance between two locations is 5-10 KM.

Is this recommended at all by PA? If yes, what kind of link is required for HA connectivity (L3, L2) for "Active-Active"?

I guess Client may consider Multi-VSYS environment too. 

 

 Would it possible to make this happen? Please share your thoughts.

 

Thank You

Hi @BrajeshPatel ,

 

Yes, it has been done many times as long as the latency is fine.  PANW unofficially recommends 20ms or better between firewalls.  Customers have reported it works fine with 80-120ms.  Check out this video starting at 1 hour 14 minutes.  Bandwidth should also be considered.  https://www.youtube.com/watch?v=4hFQypgOAGk&t=4665s

 

Thanks,

 

Tom
