Exchange Fault Tolerance - Using a 3rd party Solution

I often get asked if a partner should use Microsoft Clustering or a 3rd party solution for use with Exchange – and the simple answer usually comes down as to whether you want a supported or a non supported solution.

Article 895847 explains just why a lot of these solutions aren’t supported.

Deployment Guidelines for Exchange Server Multi-Site Data Replication gives a good overview of how Exchange can be used with a data replication storage technology.

So before you go ahead and recommend a 3rd party solution, just double check that it’s supported in the event of a failure.
