GTM design - Single LTM HA Pair split across two Data Centres
Hi,
I have two GTMs and two LTMs configured as a HA pair split evenly across two different Data Centres and a fibre connection between the LTMs to create the internal network.
We are taught that in GTM configuration each Server object can only belong to one Data Centre.
How are people dealing with the limitation of only being able to place a Server (I'm talking about GTM object) of Type BIG-IP redundant pair into one Single Data Centre object when in fact each member of the LTM HA Pair is in two separate locations serrviced by different ISPs? What kind of issues is this causing you?
I see a potential issue with distributed applications where you may want to make its availability dependent on link availability.
Any thoughts?
