Test-Cluster is a fundamental function that is needed to ensure that the cluster to be created meets Microsoft recommendations regarding Failover Clustering. It also ensures that your hardware and settings are compatible. Run Test-Cluster with all nodes and include All Tests (namely, 'Storage Spaces Direct', 'Inventory', 'Network' and 'System Configuration').
Ensure there are test-cluster passes without warnings for the 'High Throughput Configuration', while 'Basic Configuration' will receive a warning as mentioned in the previous section of this guide.
