Hi Dr. Muhammad,

 

I am running a similiar configuration where I have a pair of F5s in one datacenter and another pair in another datacenter. Each F5 grouping is active/passive. We used the GTM to essentially serve traffic accross both datacenters as an active/active scenario. This design worked, but you must keep in mind of the drawback which is that if one datacenter's LTM reached above 50% capacity based on traffic, the other datacenter could would not be able to cope with a datacenter loss. Thus we have to upgrading in any manner to keep the capacity below 50% because our requirement was that each datacenter needed to be redundant.

 

 

I hope this information helps you.

With this design - what are some methods of ensuring configs are syncrhonized with both pairs (datacentre pair and DR pair)?
