using the SAS2 integrated RAID command-line utility to configure the integrated RAID functions of
the ServeRAID H1135 controller.
Features on Demand
This topic provides information about Features on Demand.
Features on Demand provides optional software that is available for the compute node and other Flex
System resources. Features on Demand provides a convenient way for you to activate optional software
through the Flex System Manager management software (if installed), the IMM2 interface, or the CMM web
interface. Any Features on Demand software that you ordered with your compute node is preactivated
and does not require manual activation.
If you did not order Features on Demand software when you ordered the compute node, you can purchase
Features on Demand software as you would any other optional software or hardware. Instructions for
obtaining an activation key are provided with your purchase of a Features on Demand authorization code.
For information about Features on Demand, see http://www.ibm.com/systems/x/fod/.
Important:
1. If the compute node is configured in the Setup utility to boot in Legacy mode, you must leave UEFI
option ROM initialization enabled for devices for which Features on Demand feature keys are installed.
2. After you install an activation key for the first time, you might have to restart the compute node for the
Features on Demand software 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 a level
that supports the Features on Demand software.
Setting up the LAN-on-motherboard feature
This topic provides information about setting up the LAN-on-motherboard (LOM) feature.
Some models of the Flex System x220 Compute Node have an Ethernet LAN-on-motherboard (LOM)
controller integrated on the system board. The LOM provides the following features:
• One-port physical NIC mode (pNIC). 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/ configuring_io_modules.html.
• Link auto negotiation 1 Gb/1 Gb full duplex.
• Bus-mastering support.
• Direct memory access (DMA) support.
• Interoperability with existing Fibre Channel SAN infrastructures, such as switches, arrays, SRM tools,
SAN practices, and other infrastructures.
• 1 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.
• Preboot Execution Environment, UEFI, and legacy PXE.
• Wake on LAN (WOL).
