what can be the drawbacks of Vcenter HA in SRM.
If the environment is having two sites (Site1 and site2) which will be having SRM, so in this scenario will we have any benefit ? Or It will just add additional complexity.
Vcenter HA is to have high availability for your vcenter. It does not add complexity to your SRM. if both of your sites having vcenter HA, then srm also comes with high availability feature (considering your replication is good).
I do not see problem, the SRM will be triggered for a disaster recovery.
VCenter HA will be used for high availability of the service.
