24 Cabling Your Cluster Hardware
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.
NOTE: Use the same brand of NICs in a team. You cannot mix brands of teaming
drivers.
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.
Cabling Storage for Your Direct-Attached Cluster
A direct-attached cluster configuration consists of redundant Fibre Channel
host bus adapter (HBA) ports cabled directly to a Dell PowerVault MD36x0f
storage system. If a component (for example, port, cable, or the storage
controller) fails in the storage path, the MPIO software automatically
re-routes the I/O requests to the alternate path so that the storage array
continues to operate without interruption. The configuration with two
single-port HBA provides higher availability. An HBA failure does not cause
the failover cluster to move cluster resources to the other cluster node.
Figure 2-3 shows an example of a direct-attached, single cluster configuration
with redundant HBA ports installed in each cluster node.
