Intel^® 82598EB 10 GbE Controller - Overview
Figure 5-10. Single NC Package, Two NC Channels
Figure 5-11 shows an example topology for a single MC and two NC packages. In this example, one NC
package has two NC channels and the other has only one NC channel.
Figure 5-11. Two NC Packages (Left, with Two NC Channels and Right, with One NC Channel)
Scenarios in which the NC-SI lines are shard by multiple NCs (as shown in Figure 5-11) mandate an
arbitration mechanism. The arbitration mechanism is described in Section 5.4.5.1.
5.4.1.3 Data Transport
Since NC-SI uses the RMII transport layer, data is transferred in the form of Ethernet frames.
