I have 2 servers which work in conjuction, one is database server other is its application server, both servers are in same vlan, ip address of database server is hard coded in application server. Now I have a BCP/DRP site where there is the replica of the database server, now when this database server on the primary site goes down then application server should connect to BCP site database server. I see 1 solution to it but not sure that it would work:
do a NAT of the original database server ip with BCP site database server IP. Would it work and if yes then whether i would b able to perform NATTING of the same IP which is Active once and then when that server goes down.
You say both the application server and the database server are on the same VLAN and thus the traffic wouldn't go through the router for any communication between them. Any router solution to provide redundancy would only be applicable if the traffic does traverse through the router itself. Hence, you would have explore some server based solution for this setup.
