I am planning on setting up a Exchange 2007 CCR Cluster in 2 datacenters. This will be for 10-15 users and will be linked by a dedicated T-1 connection. Is a T-1 fast enough for this? If not what are the alternatives to setting 2 live Exchange servers that will contain the same mail. Juan Gutierrez

If it is only for 15 users, I am sure this will be fast enough for you. the only problem I would forsee is the requirement to "Stretch" your Subnet / VLan accross the WAN link for this to function. But if it is possible for you to do this then no sweat man. For a clearer indication of your storage requirements & recommended bandwidth sizing required for the log shipping of CCR, you can download the Exchange Server 2007 Mailbox Role Stroage Requirement Calculator Tool from here. All you do is provide some input on the first page & the others are automatically updated with the correct calculations & required / recommended sizing figures.
