Each SPARC T4-4 server contains four dual-ported Sun Dual 10 GbE SFP+ PCIe 2.0 Low Profile network interface cards (NICs). The 10 GbE NICs are installed in the following express module ports in every SPARC T4-4 server.
Express module slot 2
Express module slot 6
Express module slot 10
Express module slot 14
See Card and Port Locations (SPARC T4-4 Servers) for the location of the 10 GbE NICs.
Depending on the configuration, one or two of the ports on the 10 GbE NICs (ports 0 and 1) will be connected to the client access network. In some configurations, both ports on the same 10 GbE NIC will be part of an IPMP group to provide redundancy and increased bandwidth. In other configurations, one port from two separate 10 GbE NICs will be part of an IPMP group.
The number of physical connections to the 10 GbE client access network varies, depending on the type of domains created on each SPARC T4-4 server. For more information, see Understanding the SPARC SuperCluster T4-4 Configurations.
