Setting Up The Lan-On-Motherboard (Lom) Feature - Lenovo Flex System x480 X6 Compute Node Installation And Service Manual

2. After you install an activation key for the first time, you might have to restart the compute node for
the Feature on Demand to become active. See the documentation that comes with the software for
specific activation instructions.
3. Make sure that the UEFI code, IMM2 firmware, and all other firmware in the compute node is at the level
that supports the Feature on Demand software.
4. To configure Features on Demand in a scalable partition, see https://fod.lenovo.com/lkms.

Setting up the LAN-on-motherboard (LOM) feature

This topic provides information about setting up the LAN-on-motherboard (LOM) feature.
Some models of the Lenovo Flex System x280 X6, x480 X6, and x880 X6 Compute Node have one Ethernet
LAN-on-motherboard (LOM) controller integrated on the system board. The LOM provides the following
features:
• Two operational mode choices:
– One-port physical NIC mode (pNIC), multichannel disabled, which is the default.
– Virtual NIC mode (vNIC), multichannel enabled. vNIC mode enables up to 4 virtual NIC interfaces
per 10 Gb physical port (8 total for the LOM).
For more information about how LOM ports are mapped to switch modules in the chassis,
see http://pic.dhe.ibm.com/infocenter/ flexsys/information/topic/ com.lenovo.acc.8721.doc/

• Two options for vNIC linking:
– VNIC1, IBM Virtual Fabric mode.
– VNIC2, Switch Independent mode.
You can select these options using the Setup utility (F1).
• Link auto negotiation 10 Gb/1 Gb full duplex.
• Bus-mastering support.
• Direct memory access (DMA) support.
• Interoperability with existing FC SAN infrastructures, such as switches, arrays, SRM tools (including
Emulex utilities), SAN practices, and other infrastructures.
• Unified Ethernet-to-FC SAN connectivity provided by an FCoE switch.
• 10 Gb MAC features such as MSI-X support, jumbo frames (8 KB) support, VLAN tagging (802.1Q, PER
priority pause/priority flow control), and advanced packet filtering.
• NIC failover support.
• Support for IBM Fabric Manager (IFM).
• Preboot Execution Environment, UEFI, and Legacy PXE.
• Wake on LAN (WOL).
• SRIOV support.
• ISCSI or FCoE capabilities, which can be enabled through Features on Demand. When enabled, the ISCSI
or FCoE operations are supported on the second vNIC of the physical port.
Separate NIC, ISCSI, and FCoE drivers are provided to support all configurations. To obtain the device
drivers, go to http://www.emulex.com/downloads/ibm/vfa-software-kits.html.
No host operating system changes are required for you to use the LOM features. NIC and HBA functionality
(including device management, utilities, and other functions) are transparent to the host operating system.
