Understanding Microsoft Support of Cluster Solutions
Applies To: Windows Server 2008 R2
Microsoft supports a failover cluster solution only if it meets the following requirements:
All hardware components in the failover cluster solution are marked as "Certified for Windows Server 2008 R2."
The complete cluster configuration (servers, network, and storage) can pass all tests in the Validate a Configuration Wizard.
The hardware manufacturers' recommendations for firmware updates and software updates (patches) have been followed. Usually, this means that the latest firmware and software updates have been applied. Occasionally, a manufacturer might recommend specific updates other than the latest updates.
