IBM Flex System x240 Compute Node (E5-2600) 21
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, such as the IBM and Lenovo part number 73P4515 or 73P4516, or use the remote media
feature of the IMMv2 and the Chassis Management Module.
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 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 connection to 10 Gb and 1 Gb Flex System Ethernet switches

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
