Big-IQ DCD data replication
I would like to understand how the DCD works in BIG-IQ setup.
BIG-IP's will be pointing to DCD and BIG-IQ will pull the statistical data from DCD's.
If we have multiple DCD's, would the statistical data replicate completely between them or in parts?
If a logging profile has 2 DCD IP's configured under server address, would only the first DCD receive all the data until it goes down n then the second DCD gets the data?
If the data is replicated between DCD's then what is the need to load balance the BIG-IP traffic to DCD?
If we are load balancing the BIG-IP data to DCD, considering requests are going into diff DCD, what happens if one of the dcd goes down? will the BIG-IQ be able to pull the stats?
