MS Exchange 2007 High Availability
Posted on 2009-04-23
I am looking to implement a Microsoft Exchange 2007 mail server scenario.
Mail for our client is critical and i would like to have another mail server running at another site which is connected via a managed WAN.
In the event of a server going down we would like to switch over to the other replicating server partner and it can then become the primary reciever of all mail. But i would also like this replicating server to act as a local cache / front end server so that the mail data on the WAN is as minimal as possible.
I was thinking.
CCR with 2007 Exchange
Front End / Back End Scenario with Exchange 2007
Perhaps a secondary MX record?
Has anyone had a lot of experience with this and have any other better ideas. I have tested this scenario previously and it has worked with smaller mailbox servers. This server could potentially have multiple storage groups and 80-100GB of mail.
