Flex System x240 Compute Node (E5-2600 v2) 25

Internal tape drives

The server does not support an internal tape drive. However, it can be attached to external tape drives

using Fibre Channel connectivity.

Optical drives

The server does not support an internal optical drive option, however, you can connect an external USB

optical drive. See http://support.lenovo.com/en/documents/pd011281 for information about available

external optical drives from Lenovo.

Note: The USB port on the compute nodes supply up to 0.5 A at 5 V. For devices that require more

power, an additional power source will be required.

Embedded 10Gb Virtual Fabric Adapter

Some models of the x240 -- those with a model of the form 8737-x4x -- include an Embedded 10Gb

Virtual Fabric Adapter (VFA, also known as LAN on Motherboard or LOM) built into the system board.

Table 2 lists the 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 3R (BE3R), 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 connection to 10 Gb and 1 Gb Flex System Ethernet switches



Supports multiple virtual NIC (vNIC) functions



TCP/IP Offload Engine (TOE enabled)



SR-IOV capable



RDMA over TCP/IP capable



iSCSI and FCoE upgrade offering via FoD



The following table lists the ordering information for the IBM Virtual Fabric Advanced Software Upgrade

(LOM), which enables the iSCSI and FCoE support on the Embedded 10Gb Virtual Fabric Adapter.
