IBM Flex System x220 Compute Node 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 node supplies up to 0.5 A at 5 V. For devices that require more
power, an additional power source will be required.
Embedded 1 Gb Ethernet controller
Some models of the x220 include an Embedded 1 Gb Ethernet controller (also known as LAN on
Motherboard or LOM) built into the system board. Table 2 lists what models of the x220 include the
controller. Each x220 model that includes the controller 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 controller 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 1 Gb Ethernet controller has the following features:
Broadcom BCM5718 based

Dual-port Gigabit Ethernet controller

PCIe 2.0 x2 host bus interface

Supports Wake on LAN

Supports Serial over LAN

Supports IPv6

Note: TCP/IP Offload Engine (TOE) is not supported.
