I am looking to implement a fail over cluster over 2 sites. This is to provide disaster recovery if one of the sites is unavaliable the other SQL server will take over. I am aware of the concept of fail over clustering, I just have a few questions:
1 - what sort of link will I need between the two servers, speed etc?
2 - How much bandwith will the servers take when connected to each other in normal communication eg when replicating changes to the log and the heart beat chat.
3 - Will Fail over clustering work over diffrent domains?
