Method Hardware Components ConnectionOptical Gigabit or 10 Gigabit Ethernetnetwork adapters with LCconnectorsConnect a multi-mode optical cable between thenetwork adapters in both nodes.Dual-Port Network Adapters UsageYou can configure your cluster to use the public network as a failover for private network communications. If dual-portnetwork adapters are used, do not use both ports simultaneously to support both the public and private networks.NIC TeamingNIC teaming combines two or more NICs to provide load balancing and fault tolerance. Your cluster supports NICteaming, but only for the public network; NIC teaming is not supported for the private network or an iSCSI network.NOTE: Use the same brand of NICs in a team, and do not mix brands of teaming drivers.Storage Array(s) Cabling InformationThis section provides information for connecting your cluster to one or more storage arrays.Connect the cables between the iSCSI switches and configure the iSCSI switches. For more information see, NetworkConfiguration Recommendations.Connect the iSCSI ports from the servers and array(s) to the Gigabit switches, using proper network cables.For Gigabit iSCSI ports with RJ-45 connectors: use CAT5e or better (CAT6, CAT6a, or CAT7)For 10 Gigabit iSCSI ports:• With RJ-45 connectors: use CAT6 or better (CAT6a or CAT7)• With LC connectors: use fiber optic cable acceptable for 10GBASE-SR• With SFP+ connectors: use twinax cableCabling The Storage For Your iSCSI SAN-Attached ClusterAn iSCSI SAN-attached cluster is a cluster configuration where all cluster nodes are attached to a single storage arrayor to multiple storage arrays using redundant iSCSI switches.The following figures show examples of a two-node iSCSI SAN-attached cluster and a sixteen-node iSCSI SAN-attached cluster.Similar cabling concepts can be applied to clusters that contain a different number of nodes.NOTE: The connections listed in this section are a representative of one proven method of ensuring redundancy inthe connections between the cluster nodes and the storage array(s). Other methods that achieve the same type ofredundant connectivity may be acceptable.14
