IBM Flex System x240 Compute Node
16
Embedded 10Gb Virtual Fabric Adapter
Some models of the x240 include an Embedded 10Gb Virtual Fabric Adapter (VFA, also known as LAN
on Motherboard or LOM) built into the system board. Table 2 lists what models of the x240 include the
Embedded 10Gb Virtual Fabric Adapter. Each x240 model that includes the embedded 10Gb VFA also
has the Compute Node Fabric Connector installed in I/O connector 1 (and physically screwed onto the
system board) to provide connectivity to the Enterprise Chassis midplane. Figure 3 shows the location of
the Fabric Connector.
The Fabric Connector enables port 1 on the embedded 10Gb VFA to be routed to I/O module bay 1 and
port 2 to be routed to I/O module bay 2. The Fabric Connector can be unscrewed and removed, if
required, to allow the installation of an I/O adapter on I/O connector 1.
The Embedded 10Gb VFA is based on the Emulex BladeEngine 3 (BE3), which is a single-chip, dual-port
10 Gigabit Ethernet (10GbE) Ethernet Controller. These are some of the features of the Embedded 10Gb
VFA:
PCI-Express Gen2 x8 host bus interface
Supports multiple virtual NIC (vNIC) functions
TCP/IP Offload Engine (TOE enabled)
SRIOV capable
RDMA over TCP/IP capable
iSCSI and FCoE upgrade offering via FoD
The following table lists the ordering information for the IBM Flex System Embedded 10Gb Virtual Fabric
Upgrade, which enables the iSCSI and FCoE support on the Embedded 10Gb Virtual Fabric Adapter.
