This offered a method for customers to find out whether a proposed cluster solution was verified to work with a particular operating system.
For more information about this method for qualifying clusters, see Knowledge Base article 309395, "The Microsoft support policy for server clusters, the Hardware Compatibility List, and the Windows Server Catalog" on the Microsoft Web site at:

The Microsoft support policy is also described in Knowledge Base article 943984, "The Microsoft Support Policy for Windows Server 2008 Failover Clusters" on the Microsoft Web site at:
Link Id=111552 Before the introduction of cluster validation in Windows Server 2008, the process for defining whether Microsoft supported a particular cluster solution was handled in a completely different manner.
For a proposed solution to qualify, it had to appear in its entirety on the Windows Server Catalog Web site ( Before a proposed solution could appear on this Web site, the vendor was required to run a series of tests (provided by Microsoft) on the hardware and then upload the results to Microsoft.
After the vendor verified the solution, it would be listed on the Windows Server Catalog Web site.
The cluster validation wizard is a feature that is integrated into failover clustering in Windows Server 2008 and Windows Server 2008 R2.
With the cluster validation wizard, you can run a set of focused tests on a collection of servers that you intend to use as nodes in a cluster.
