SUMMARY
This article describes the Microsoft support services that are currently available for Microsoft Exchange Server installations that are running with a third-party Cluster service.



MORE INFORMATION
Microsoft Product Support Services (PSS) supports Microsoft Exchange Server clustering based on the failover clustering features of the Microsoft Cluster Service (MSCS). The MSCS is provided with applicable versions of Microsoft Windows operating system software. To be fully supported by PSS, a Microsoft Exchange installation that is running on MSCS must be installed on hardware that has passed Windows Catalog testing as a cluster system. For more information about the Microsoft support policy for server clusters and the HCL, click the following article number to view the article in the Microsoft Knowledge Base:

309395 The Microsoft support policy for server clusters, the Hardware Compatibility List, and the Windows Server Catalog

Several third-party vendors offer clustering services and solutions for applicable versions of Microsoft Windows operating system software that do not rely on MSCS. We do not perform in-depth testing of applicable versions of Windows or Exchange Server software with such vendor services and solutions. Additionally, there is no Microsoft hardware or application certification program for these solutions. Therefore, we cannot provide information about the actual performance or interaction of third-party clustering services and solutions that are running Exchange.

PSS will try to help a customer troubleshoot and provide support for an Exchange-related issue when Exchange is installed on a third-party clustering solution. PSS will try to help a customer with such issues until it is reasonably believed that the cause of the issue is an incompatibility between the third-party clustering solution and Exchange. As part of making this determination, PSS may try to independently reproduce the issue. If the issue cannot be reproduced in a fully supported Exchange clustering environment (for example, MSCS clustering on a Windows Catalog certified cluster system), PSS may refer the affected customer to the vendor of the third-party clustering solution, or suggest removing the third-party solution to help resolve the issue.

To be very clear, removal of the third-party clustering solution is not a precondition to receiving PSS’s support services. However, if less drastic troubleshooting efforts do not effectively resolve the issue, and there is a reasonable basis for PSS to believe that the third-party clustering solution may be the cause of the problem, PSS may have to request that the customer remove the third-party solution in order to continue troubleshooting. Otherwise, PSS may have to refer the customer to the vendor of the third-party clustering solution for additional troubleshooting support.

The customer will be completely responsible for engaging a vendor’s support organization. PSS will try to provide the customer with reasonable assistance in working with a vendor’s support organization to help resolve a customer’s Cluster service issues. However, PSS should not be considered the primary liaison between the customer and the vendor. We strongly recommend that customers develop support relationships with each vendor whose hardware or software is part of their respective Exchange solution.

The following table outlines the specific versions of Exchange Server and Windows software that are required to create MSCS-based clusters are that running Exchange.
