18 IBM Flex System V7000 Storage Node Introduction and Implementation Guide
Embedded 10 Gb Virtual Fabric Adapter
Some models of the x240 include an Embedded 10 Gb Virtual Fabric Adapter (VFA, also
known as LAN on Motherboard or LOM), built into the system board. Each of these models
that includes the embedded 10 Gb 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.
I/O expansion
The x240 has two PCIe 3.0 x16 I/O expansion connectors for attaching I/O adapter cards.
There is also another expansion connector designed for future expansion options. The I/O
expansion connectors are a very high-density 216 pin PCIe connector. By installing I/O
adapter cards, it allows the x240 to connect with switch modules in the IBM Flex System
Enterprise Chassis.
