IBM Flex System V7000 Storage Node Introduction and Implementation Guide
Each IBM Flex System x220 Compute Nodehas an Integrated Management Module version 2
(IMMv2) onboard and uses the Unified Extensible Firmware Interface (UEFI).
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. 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.
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.
1.4.4 IBM Flex System p260 and p24L Compute Nodes
The IBM Flex System p260 Compute Node and IBM Flex System p24L Compute Node are
based on IBM POWER architecture technologies. These compute nodes run in IBM Flex
System Enterprise Chassis units to provide a high-density, high-performance compute node
environment, using advanced processing technology. The IBM Flex System p24L Compute
Node shares several similarities to the IBM Flex System p260 Compute Node in that it is a
half-wide, Power Systems compute node with two POWER7 processor sockets,16 memory
slots, two I/O adapter slots, and an option for up to two internal drives for local storage. The
IBM Flex System p24L Compute Node is optimized for lower-cost Linux installations.
