Dell EMC AX4-5 manual Cabling the Storage Systems, NIC Teaming

Using Dual-Port Network Adapters

You can configure your cluster to use the public network as a failover for private network communications. If dual-port network adapters are used, do not use both ports simultaneously to support both the public and private networks.

NIC Teaming

NIC teaming combines two or more NICs to provide load balancing and fault tolerance. Your cluster supports NIC teaming, but only in a public network; NIC teaming is not supported in a private network.

You should use the same brand of NICs in a team, and you cannot mix brands of teaming drivers.

Cabling the Storage Systems

This section provides information for connecting your cluster to a storage system in a direct-attached configuration, or to one or more storage systems in a SAN-attached configuration.

Cabling Storage for Your Direct-Attached Cluster

NOTE: Ensure that the management port on each storage processor is connected to the storage server with the management station, using an Ethernet network cable.

Adirect-attached cluster configuration consists of redundant Fibre Channel host bus adapter (HBA) ports cabled directly to a Dell/EMC storage system. Direct-attached configurations are self-contained and do not share any physical resources with other server or storage systems outside of the cluster.

Figure 2-4 shows an example of a direct-attached, single cluster configuration with redundant HBA ports installed in each cluster node.
