Okay I been assigned a project from IT Director and I am new to Exchange 2007. Please understand I always taken care of Exchange on a one box situation.At the moment here is our exchange envir. Single Exchange 2003 Server in Hillside and a Front End Server in Hillside for OWA.What he would like to do is have the following:We have 4 locations he would like to have Exchange 2007 with clustering and have data replicate between these locations. The locations are connected over T3 connections in different subnets. It is a Single Forest with Single domain. (abc.com). This is what he would like to see. Ventura, CA : 192.168.31.0/242 Boxes with Exchange 2007 ClusteringHillside, NJ: 192.168.3.0/242 Boxes with Exchange 2007 ClusteringWeehawken, NJ: 192.168.6.0/242 Boxes with Exchange 2007 ClusteringChicago, IL: 192.168.1.0/242 Boxes with Exchange 2007 Clustering We would like all of the locations to replicate data from one site in Hillside, NJ and set MX records according to Hillside, 1Weehawken, 2Chicago, 3Ventura, 4 I am not sure what product I would use to cluster the data from one exchange location to another. What would be the best possible way to do this? Thanks

Depending on your needs one of the following should work for you. Both are built into exchange 2007(SP1) http://technet.microsoft.com/en-us/library/bb124521.aspx http://technet.microsoft.com/en-us/library/bb676502.aspx

Butler, We are looking to do this. 1. OWA Front End on one server with minium amount of ram and storage space on Dell Power Edge 1950. 2. Two Exchange 2007 Enterprise on Dell Power Edge 2950 with 8 Gigs ram and 1 Terabyte of space across 2 datacenters in different subnets We would like one of these exchange servers to be a fail over server and cluster them together. I am really interested in the http://technet.microsoft.com/en-us/library/bb124521.aspxbut was curious on the CCR can be combined with standby continuous replication (SCR)CCR can be combined with SCR to replicate storage groups locally in a primary data center (using CCR for high availability) and remotely in a secondary or backup datacenter (using SCR for site resilience). The secondary datacenter could contain a passive node in a failover cluster that hosts the SCR targets. This type of cluster is called a standby cluster because it does not contain any clustered mailbox servers, but it can be quickly provisioned with a replacement clustered mailbox server in a recovery scenario. If the primary datacenter fails or is otherwise lost, the SCR targets hosted in this standby cluster can be quickly activated on the standby cluster. Is this the piece to use the clustering across datacenters?

Yes, your understanding is correct, we can use CCR to replicate storage groups locally and SCR to replicate one storage group to a remote datacenter. For more informationm, please use Exchange Team blog clustering site. http://msexchangeteam.com/archive/category/3896.aspx -Jason
