Hi,

I would like to ask an example configuration for disaster recovery deployment. What are the options to select in the GSLB algorithm for this kind of deployment. I can't find this topic in the manual.


Thanks,

Dannel

Hi Dannel,

For disaster recovery, you want everybody sent to "the primary datacenter" when this one is UP.
The "backup datacenter" will be used only if the:
. datacenter is down (lost Internet access for instance)
. or all the servers/applications are down in the datacenter (so VIP is down in the datacenter)


For that the easiest option is to use:
. "admin-preference" under the GSLB site (with a higher preference for the primary site)
. "admin preference" under the GSLB policy (=> the site VIP with higher preference is always replied - as long as UP of course)

Here is attached a CLI configuration example.

Thanks,
Dimitri

Hello ddesmidt,
Maybe this topic is to old so I cannot see the attachment. Can you upload a similar configuration for this deployment.

And how to deploy GSLB for Active/Active application in both site ?

Thank you.
