Cluster with two geographic locations?

Hi there,

 

I have two different locations that are connected by a VPN link.

I want both locations to work even if the other side goes down.

I'm unsure what should I do?

 

# Publisher + Subscriber?

Will subscriber authenticate users when publisher is down?

Will OnGuard work? (requires health to be written to db?)

Will [Machine Authenticated] work for new machines? (requires role to be written to db?)

 

# Publisher + Standby Publisher?

if the link goes down, both Publishers will become active. What happens when the link goes up again?

Can I do automatic failback so that after the link comes up the promoted publisher gets back to standby?

 

Another related question: 

Will data that I insert to the database using appexternal also get replicated from Publisher to Subscribers?

 

Thanks

This interests me too. We have two separate locations too so can't have virtual IP for Clearpass servers.

Wondering also if I should relay DHCP to both servers or will it mess up the profiling?

Hi,

 

Please take a read of the following document.

CPPM TechNote - Clustering Design Guidelines v1.2

 

This should help you out with the information you are looking for.
