This required 10-GbE network connects the SPARC T5-8 servers to your existing client network and is used for client access to the servers. 10-GbE NICs installed in the PCIe slots are used for connection to this network. The number of 10-GbE NICs and the PCIe slots that they are installed in varies depending on the type of configuration that is set up on the SPARC T5-8 server.
