I'm looking for an approach to name resolution for a DR site. Here is my setup.
-I have a prod and DR site, which are on different subnets in different geographic locations
-I'm using EMC recoverpoint to replicate a datastore containing VM's, which is inside of a LUN. This is one-way continuous replication to a remote site.
-I'm using ESX 5.1 without SRM, so my DR failover is mostly manual.
-I have a single windows domain.
For any given VM, I have 2 virtual nics, each on the Prod and DR networks, respectively, and resolve to a single name, eg:
vm1.domain.local 10.10.9.141 (prod IP)
vm1.domain.local 10.50.1.141 (DR IP)
What is the easiest way to get the name to resolve to the Prod IP when the Prod is active, and the DR IP when DR is active? Should I point the DR site to a non-AD-integrated DNS server, so that the prod and DR DNS is kept separate?
Thanx
Karl
