How is MSCS cluster hardware validated?
Complete cluster configurations (two particular servers plus a storage solution) are tested and validated using the Microsoft Cluster Hardware Compatibility Test (HCT). Anyone with an appropriate lab setup can run the test. The test procedure takes at least four days, and one-half of a full-time-equivalent Microsoft Certified Professional. The result of a successful test is an encrypted file that is returned to Microsoft Windows Hardware Quality Lab (WHQL). Upon validation of the test results, WHQL posts the tested configuration on the Microsoft Hardware Compatibility List (HCL).
