Figure 3-3. SAS-Based Hyper-V Host Cluster Configuration
NOTE: Even though it is possible to configure a 4-node Hyper-V Host Cluster with a
Dell MD3000 SAS Storage Array, Dell recommends only a 2-node Hyper-V Host
Cluster with the MD3000 SAS Array. This is to ensure that the configuration is more
reliable. In a 4-node configuration, there is only one path from any one node to the
storage array and that does not provide multi-path resiliency for the solution.
