Thanks Mr Luke Lehman for your response . I will just explain my setup . We have Two DC and each DC hosting pair of LTM & Standalone GTM .
When User Request say it hits DNS ( Which is Hosted Somewhere in Cloud say GO Daddy ) which then delegates the NS service to GTM by using the subdomain .Once request reaches the GTM it searches for Available LTM VIP .
We are using SNI for the VIP .
Integrating Silverline in front of your data centers does provide the ability to check which DCs are available and load balance the traffic as necessary. I don't want to undervalue GTM though as it still has a ton of value-add.
One thing that you could do is leverage GTMs Topology capabilities, to do some testing. For example, when you were trying out Silverline, you could create the necessary topology config to reply to only your machine's DNS queries to the Silverline Proxy IP (which would then LB to one of your 2 DCs).
