Exchange 2010 HA/Failover Options

Hi

We currently have an on premise Exchange 2010 server with approximately 300 users.  The setup is a single Exchange Server running all the roles. I would like to setup some sort of fail-over/HA and have a second server at another location.  We have a fast Internet line and could establish a 30-50MB connection to another location we have in mind.
It would be great if we had an issue on-premise for our device at the second location to take over servicing the users automatically, if this isn’t as straight forward and we had to make some changes manually this would also be an option we could consider.  Or if there is an even better way to configure I am open to suggestions?

thanks

Exchange 2010 uses Database Availability Groups to handle failover capabilities. It's a pretty big topic to go over in an answer on here, so http://technet.microsoft.com/en-us/library/dd979799%28v=exchg.141%29.aspx has some good information for you to look at. Basically you can set up another exchange server with all the roles in another site and install Cluster Services on both servers, then set up the DAG. Note that if you don't have Windows 2008 Enterprise (or higher)  or 2012 Standard you won't be able to use Cluster Services or DAGs unless you get one of those installed with exchange at both sites.
