18 Cabling Your Cluster Hardware
NIC Teaming
NIC teaming combines two or more NICs to provide load balancing and 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.
Cabling the Storage Systems
This section provides information for connecting your cluster to a storage
system in a direct-attached configuration, or to one or more storage systems
in a SAN-attached configuration.
Cabling Storage for Your Direct-Attached Cluster
NOTE: Ensure that the management port on each storage processor is connected
to the storage server with the management station, using an Ethernet network
cable.
A direct-attached cluster configuration consists of redundant Fibre Channel
host bus adapter (HBA) ports cabled directly to a Dell|EMC storage system.
Direct-attached configurations are self-contained and do not share any
physical resources with other server or storage systems outside of the cluster.
Figure 2-4 shows an example of a direct-attached, single cluster configuration
with redundant HBA ports installed in each cluster node.
