Dell recommends you to use five distinct subnets for Scale-Out File Server configurations. Two high-speed storage networks are used for external client communication (L3–routable). Different two subnets are used for intra-cluster communication (do not require L3 routing).
The fifth subnet is used for cluster management and Active Directory integration. This subnet must leverage an existing network infrastructure, if required. You must have each redundant pair of subnets routed through two physically separate switches. Internal communication between storage nodes is performed by the dual 10 GbE ports on the Network Daughter Card (NDC) in the storage node.
