The node in Bay 1 in Figure 1-14 shows that when shipped with a LOM, the LOM connector 
provides the link from the node motherboard to the midplane. Some nodes do not ship with 
LOM.

If required this LOM connector may be removed and an I/O expansion adapter installed in its 
place. This is shown on the node in Bay 2 in Figure 1-14.

The IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch provides support for 
L2 and L3 switching, Converged Enhanced Ethernet (PFC, ETS, DCBX), Fibre Channel over 
Ethernet (FCoE), NPV Gateway and Full Fabric Fibre Channel Forwarder (FCF).

The switch has the following major components:

��

42 10 Gb Ethernet internal ports and twenty-two external ports. External ports are 
arranged as two (small form-factor pluggable plus) SFP+ ports

��

12 SFP+ Omni Ports 

��

2 Quad Small Form-Factor Pluggable Plus (QSFP+) ports.

��

Each Omni Port is capable of running in 10 Gb Ethernet or 4/8 Gb FC mode with 
auto-negotiation capability.

��

Support for Converged Enhanced Ethernet (CEE) and Fibre Channel over Ethernet 
(FCoE) over all Ethernet ports including Omni Ports (in Ethernet mode).

��

Support for the Full Fabric FCF (Fibre Channel Forwarder) and NPV gateway.

��

Support for full fabric FC services including Name Server, hardware-based Zoning.

��

Support for IBM vNIC (virtual network interface card) Virtual Fabric Adapter with Single 
Root I/O Virtualization (SR-IOV) capability.
