We currently have a production and a failover site that each have their own Exchange 2000 server. Each sites Exchange Server is connected to a SAN which replicates data between the two sites. The sites are currently connected by a VPN with about 1MB of bandwidth, but will soon be connected with 40-45MB of bandwidth. We are in the process of installing an Exchange 2003 Cluster at our production site and migrating all of our users to that. We want to install an Exchange 2003 server at our failover site but I'd like some ideas and best practices on how to have the failover site server configured for best/most uptime incase of a disaster.
Some things I've read say that it has to be a cold standby server that gets booted up and the database restored back onto it if the production site becomes unavailable. It seems like there would be an automatic or "hot" way to do this.
