Cabling Your Power Supplies
NAS cluster configurations require cabling for the Fibre Channel storage systems, cluster interconnects, client network
connections, and power connections. These systems and components are interconnected to provide four independent
functions as listed in Table 3-1 , each of which is described in more detail throughout this section.
Table 3-1. Cluster Cabling Components
Components Description
Shared storage
system
Connects the servers' redundant HBAs to the cluster's shared storage system. The server-to-storage
connection can be achieved through a direct connection or through a SAN. See " Direct-Attached
Cluster " and " SAN-Attached Cluster Configurations " for more information.
Cluster
interconnect
(private network)
Connects the cluster nodes to each other to exchange cluster information and health status, such as
the cluster heartbeat and access to the quorum resource. This connection can be made by using an
Ethernet NIC and cabling that is connected to each cluster node.
NOTE: If more than two nodes are deployed, you will need an Ethernet switch.
See the Platform Guide for a list of supported NICs for your configuration.
Network
connection for
public traffic
(public network)
Provides a connection between each cluster node and the public network. This connection can be made
using an Ethernet NIC and cabling that is connected to the public network.
See the Platform Guide for a list of supported NICs for your configuration.
Power connection Provides a connection between the power supplies in your system and the power source. By using
power strips or PDUs and separate AC circuits, the cluster can fully utilize the redundant power
supplies.
Fibre Channel Cable Connectors
NAS Fibre Channel cluster require two types of fiber optic connectors to connect the various Fibre Channel storage
components to the cluster configuration:
Duplex LC multimode fiber optic connector
Duplex SC multimode fiber optic connector
The duplex LC multimode fiber optic connector (see Figure 3-1 ) is used to connect a Fibre Channel switch to a Fibre Channel
HBA on a cluster node or to a storage system. This type of connection requires fiber optic cables with duplex LC multimode
fibre optic connectors.
