20 Cabling Your Cluster Hardware
NOTE: Throughout this document, Ethernet refers to either Gigabit Ethernet or
10 Gigabit Ethernet.
Using Dual-Port Network Adapters for Your Private Network
You can configure your cluster to use the public network as a failover for
private network communications. However, if dual-port network adapters are
used, do not use two ports simultaneously to support both the public and
private networks.
NIC Teaming
Network Interface Card (NIC) teaming combines two or more NICs to
provide load balancing and/or fault tolerance. Your cluster supports NIC
teaming, but only in a public network; NIC teaming is not supported in a
private network.
Table 2-2. Private Network Hardware Components and Connections
Method Hardware Components Connection
Network switch Gigabit or 10 Gigabit
Ethernet network
adapters and switches.
Depending on the hardware,
connect the CAT5e or CAT6
cables, the multimode optical
cables with Local Connectors
(LCs), or the twinax cables
from the network adapters in
the nodes to a switch.
Point-to-Point (two node
cluster only)
Copper Gigabit or 10
Gigabit Ethernet network
adapters with RJ-45
connectors.
Connect a standard CAT5e or
CAT6 Ethernet cable between
the network adapters in both
nodes.
Copper 10 Gigabit
Ethernet network
adapters with SFP+
connectors
Connect a twinax cable
between the network adapters
in both nodes.
Optical Gigabit or 10
Gigabit Ethernet network
adapters with LC
connectors
Connect a multi-mode optical
cable between the network
adapters in both nodes.
