Cabling Your Cluster Hardware 19
Cabling the Private Network
The private network connection to the nodes is provided by a different
network adapter in each node. This network is used for intra-cluster
communications. Table 2-2 describes three possible private network
configurations.
NOTE: Throughout this document, Gigabit Ethernet is used to refer to either Gigabit
Ethernet or 10 Gigabit Ethernet.
Using Dual-Port Network Adapters
You can configure your cluster to use the public network as a failover for
private network communications. If you are using dual-port network adapters,
do not configure both ports simultaneously to support both public and
private networks.
NIC Teaming
NIC teaming combines two or more NICs to provide load balancing and fault
tolerance. Your cluster supports NIC teaming, only in a public network. NIC
teaming is not supported in a private network.
Use the same brand of NICs in a team. Do not mix brands in NIC teaming.
Cabling the Storage Systems
This section provides information on cabling your cluster to a storage system
in a direct-attached configuration or to one or more storage systems in a SAN-
attached configuration.
