I got an e-mail from Gloria asking, “My group is currently looking at the evaluation software for TFS. I was wondering if it's possible to run TFS on two servers in tandem, so that in case one goes down, the system will fail over to the other. If so, can you advise us how to keep the two synchronized?”
In v1, we support clustering on the data tier and warm standby on the application tier. For more information, see Ensuring Team Foundation Server Availability.
