Cabling Your Cluster Hardware
19
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.
