Hi.
Primary site setup there are two servers as below
1. Application server (IIS Role)
2. Database server ( SQL 2012 enterprise edition)
Now management decide to configure DR setup in remote datacenter,
As per my suggestions
1. Database mirroring can be configured in both the DB server due to there is no local HA setup in Primary datacenter. so I suggest to configure database mirroring for HA as well as DR setup with witness server for automatic failover.
2. Remote datacenter 1 DB server, 1 Appl.server
3. Alwayson-setup ? can be use it?
(Note: Primary & Remote datacenters are both are same domain and all the servers member of same domain groups and same DNS name).
Pl. advice and your suggestions
