Thanks Jaime
As per the document i have doubts
A subcluster contains a maximum of two servers and allows for users associated with one server of the subcluster to use the other server in the subcluster automatically if a failover event occurs. Cisco IM and Presence Service does not provide failover between subclusters.
As per document If this is not providing failover between subcluster then how my users will shift to DR subscriber in case of main dc fails , because Main dc already having 1 Subscriber and 1 publisher which is part of one subcluster and we cannot add more then 2 servers in 1 subcluster

Your option will be keep one server in HQ and move the subscriber to DR.

Hi,
The HA is between servers in a subcluster, not between subclusters.
Maybe I'm confused by your requirements, but it would seem like for each subcluster you would put one of your servers in one DC and the other in the other DC. Each server in a subcluster should be on a different physical server. I try to put them on different VLANs and their disks in different LUNs for a SAN. If you distribute the two servers in the subcluster across different DCs even better.

The solution may not operate properly with nodes out of service (particular with Jabber and MRA) . I would review your options with your virtualization solution to offer a recovery method by moving the guest in case of site failure, and physically diversify your hosts and VM guest assignments.
