Resumen del manual
Figure 2-4 shows an example of a direct-attached, single cluster configuration with redundant NIC ports installed in each cluster node. Figure 2-4. Direct-Attached Cluster Configuration cluster node private network public network cluster node iSCSI connections iSCSI connections storage system Cabling Your Cluster Hardware Each cluster node attaches to the storage system using CAT5e or CAT6 LAN cables with RJ45 connectors that attach to Gigabit Ethernet NICs in the cluster nodes and the Gigabit iSCSI storage processor (SP) ports in the Dell|EMC storage system. NOTE: The connections listed in this section are representative of one proven method of ensuring redundancy in the connections between the cluster nodes and the storage system. Other methods that achieve the same type of redundant connectivity may be acceptable. Cabling a Two-Node Cluster to an AX4-5i Storage System Figure 2-5 illustrates methods of cabling a two-node direct-attached cluster to an AX4-5i storage array. 1 Connect cluster node 1 to the storage system. a Install a cable from cluster node 1 iSCSI NIC 0 (or NIC port 0) to SP-A iSCSI port 0. b Install a cable from cluster node 1 iSCSI NIC 1 (or NIC port 1) to SP-B iSCSI port 0. 2 Connect cluster node 2 to the storage system. a Install a cable from cluster node 2 iSCSI NIC 0 (or NIC port 0) to SP-A iSCSI port 1. b Install a cable from cluster node 2 iSCSI NIC 1 (or NIC port 1) to SP-B iSCSI port 1. NOTE: The cables are connected to the storage processor ports in sequential order for illustrative purposes. While the available ports in your storage system may vary, NIC 0 (or NIC port 0) and NIC 1 (or NIC port 1) must be connected to SP-A and SP-B, respectively. Cabling Your Cluster Hardware Figure 2-5.

An iSCSI SAN-attached cluster configuration provides more flexibility, expandability, and performance than a direct-attached configuration. Figure 2-6 shows an example of a two node iSCSI SAN-attached cluster. Figure 2-7 shows an example of an eight-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 representative of one proven method of ensuring redundancy in the connections between the cluster nodes and the storage system. Other methods that achieve the same type of redundant connectivity may be acceptable. Cabling Your Cluster Hardware Figure 2-6.
