Four sets of default IP addresses are assigned at manufacturing:
Management IP addresses – IP addresses used by Oracle ILOM for the SPARC T4-4 servers, Exadata Storage Servers, and the Sun ZFS Storage 7320 storage controllers.
Host IP addresses – Host IP addresses used by the SPARC T4-4 servers, Exadata Storage Servers, and the Sun ZFS Storage 7320 storage controllers.
InfiniBand IP addresses – InfiniBand interfaces are the default channel of communication among SPARC T4-4 servers, Exadata Storage Servers, and the Sun ZFS Storage 7320 storage controllers. If you are connecting a SPARC SuperCluster T4-4 to another SPARC SuperCluster T4-4 or to an Oracle Exadata or Exalogic machine on the same InfiniBand fabric, the InfiniBand interface enables communication between the SPARC T4-4 servers and storage server heads in one SPARC SuperCluster T4-4 and the other SPARC SuperCluster T4-4 or Oracle Exadata or Exalogic machine.
10 GbE IP addresses – The IP addresses used by the 10 GbE client access network interfaces.
