Licensing for HA setup

with active/active HA you need all licences/subscriptions two times.

with active/standby HA you need licences once.

but consider ... with active/active only one device gets the packets/traffic and delegates some of them to second node.

you do not double the performance.

so mostly we suggest to use active/standby HA ... possible with the next bigger device.

the takeover-time is the same with active/standby HA as active/active.

Hi Dirk, 

Thanks for your advise.

So in a active/standby HA setup, suppose the switching happens automatically when the active site becomes inaccessible, how do I automatically update the license so that the newly activated node gets the license?

Thanks

An Sophos HA (active/standby or active/active) is one system

Booth nodes share one configuration and one license.

If you power down the cluster and starts booth nodes without connection, you see the same license at booth devices.

The Failover happens automatically when the active site becomes inaccessible or a link goes down at the master while not at the slave.

Dirk's answers are ones you can trust.
