In my opinion this 5-node set up is very elaborate and should work , which is distributed different across different seismic zone (across Mumbai (primary DC) and Chennai (DR site)) . Probably below mentioned parameters were factored when designing the system
network latency between Mumbai and Chennai
application switch over in case of fail-over and the downtime.
