The Hadoop cluster has multiple network connections. Each node in the cluster has a minimum of three physical connections:
Server Management
1GbE primary and secondary connections
InfiniBand
40Gb/sec redundant connections used for the Hadoop cluster and connectivity to edge nodes
Public Interfaces
1GbE or 10GbE external interfaces used to access customer network resources and for inbound customer client requests to the cluster

Hadoop communicates on the InfiniBand internal network. The corporate DNS database must include the fully-qualified Hadoop node names.

Teradata installs and configures networking in the system, but the public interfaces can be customized.

For setting up external connectivity to a customer LAN or external edge node, see Setting Up External Access.
