Cabling Your Cluster Hardware 23

Cabling Your Private Network

The private network connection to the cluster nodes is provided by a second or subsequent
network adapter that is installed in each node. This network is used for intracluster
communications. Table 2-3 lists the required hardware components and connection method for
three possible private network configurations.
NOTE: On certain Microsoft® Windows® 2000 Advanced Server, Windows Server™ 2003
configurations, using an Ethernet cable in a point-to-point connection can impact node-to-node
communications. See Microsoft Knowledge Base articles 239924, 242430, 254651, and 258750 at
www.microsoft.com for more information. This issue has been corrected in Windows Server 2003.

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.
You should use the same brand of NICs in a team, and you cannot mix brands of
teaming drivers.
