Cabling the Private Network The private network connection to the nodes is provided by a different network adapter in each node. This network is used for intra-cluster communications. Table 2-2 describes three possible private network configurations. Table 2-2. Private Network Hardware Components and Connections Method Hardware Components Connection Network switch Gigabit Ethernet network Connect standard Ethernet cables adapters and switches from the network adapters in the nodes to a Gigabit Ethernet switch. Point-to-Point Copper Gigabit Ethernet Gigabit network adapters Ethernet (two-node clusters only) Connect a standard Ethernet cable between the Gigabit Ethernet network adapters in both nodes. NOTE: Throughout this document, Gigabit Ethernet is used to refer to either Gigabit Ethernet or 10 Gigabit Ethernet. Using Dual-Port Network Adapters You can configure your cluster to use the public network as a failover for private network communications. If you are using dual-port network adapters, do not configure both ports simultaneously to support both 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, only in a public network. NIC teaming is not supported in a private network. Use the same brand of NICs in a team. Do not mix brands in NIC teaming. Cabling the Storage Systems This section provides information on cabling your cluster to a storage system in a direct-attached configuration or to one or more storage systems in a SANattached configuration.
