Exchange 2007 SP1 Failover Options

Good Afternoon,

I currently work for a company that has around 100 employees.  We are using a single, virtualized (though the Exchange server is currently the only server on the host) Exchange 2007 SP1 server, on a Server 2008 R2 system, with three databases on it.  We have another physical server that we can use for some type of redundancy, that is identical in specs to the current Exchange server.  I would like to know what my best options are as far as using these two servers to provide high availability to our employees.  I have read some about SCR, but it seems that you cannot do this with more than one database.  Also, the hub transport roles, etc. are all on the Exchange server itself.  Can anybody point me in the right direction?

There are many options for repplicating logs in Exchange 2007 (LCR, SCR, CCR)

It looks that the best option for you is tu use SCR, it allows you to replicate the desired databases in another mailbox server and at the same time be able to include the other basic roles (CAS, HUB)

You can replicate more than one DB - IF - you accomplish the requirements. One of the main things is that each DB needs to be alone in the Storage Group. So... it means that if you have Exchange 2007 Standard edition you are not able to make it unless you configure just one DB in your storage group. If you are using Exchange 2007 Enterprise edition you can configure your three DBs in different storage groups and them configure the repplication
