IBM Ethernet Switch B24X 11
10 Gbps Ethernet connectivity is not standard in most System x servers, and a 10 GbE NIC or 10 GbE
CNA must be installed. Only the IBM System x3850/3950 X5 series (except for the ARx model) come
standard with a customized Emulex Virtual Fabric Adapter. Table 6 lists the 10 GbE adapters that are
available for IBM System x servers.
