This article describes the Microsoft support policy for Windows Server 2012 failover cluster implementation. Microsoft Customer Service and Support supports Windows Server 2012 failover clusters that meet the following criteria:
Changes in Windows Server 2012Before you create a cluster, run a failover cluster validation test on fully configured hardware that is running Windows Server 2012. The failover cluster validation test identifies potential hardware and software configuration issues. Run the failover cluster validation test on hardware and software that is certified under the Windows Server Logo Program for Windows Server 2012.
To configure a failover cluster in Windows Server 2012, the failover cluster must pass the required failover cluster validation tests. The failover cluster validation tests perform the following functions on the collection of servers that you intended to use as a cluster:
For a more information about how to validate hardware for a Windows Server 2012 failover cluster, go to the following Microsoft website:
Note All reports that the Validate a Configuration Wizard in the Failover Cluster Manager snap-in generates are stored in the %systemroot%\cluster\Reports folder.
Run the failover cluster validation tests on a fully configured failover cluster before you install the Failover Clustering feature. The failover cluster is valid if it receives one of the following indicators for each test in the Summary Report:
Run the validation tests when a major component of the cluster is changed or updated. For example, run the validation tests when you make the following configuration changes to the failover cluster:
When an underlying storage configuration change or problem causes a cluster storage failure, Microsoft Support may also request that you run the validation tests on production clusters. The relevant disk resources and the resources on which the disks depend are taken offline during the test. Therefore, run the validation tests when the production environment is not being used.
Note The ability to specify one or more disks to be included in the failover cluster validation tests is added in Windows Server 2012.

Microsoft supports the failover clusters that are listed under Cluster Solutions on the Windows Server Catalog for the following versions of Windows Server:
