Abstract

The Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network adapter that supports Ethernet, FCoE, and iSCSI protocols as standard. The EN4172 2-port 10Gb Ethernet Adapter is a similar adapter that supports Ethernet protocols. Both adapters also support virtual network interface controller (vNIC) capability, which helps clients to reduce cost and complexity. These adapters are based on the Broadcom BCM57840 controller.

Changes in the December 11 update:
* Added x440 (E5-4600 v2) to the server support table
* Updated the UFP information

Introduction

The Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network adapter that supports Ethernet, FCoE, and iSCSI protocols as standard. The EN4172 2-port 10Gb Ethernet Adapter is a similar adapter that supports Ethernet protocols. Both adapters also support virtual network interface controller (vNIC) capability, which helps clients to reduce cost and complexity. These adapters are based on the Broadcom BCM57840 controller.

The CN4022 and EN4172 are shown in the following figure. The adapters are physically identical.

Did you know?

The CN4022 is based on the industry-standard PCIe architecture and is ideal for clients who use 10 GbE in their network infrastructure and who are looking for an entry price point for FCoE or iSCSI capabilities. The adapter ships standard with support for FCoE and iSCSi and with vNIC features that allow each physical port of the adapter to be virtualized into four vNICs.

* Certain models of the x240 -- those with a model of the form 8737-xMx -- have one CN4022 2-port 10Gb Converged Adapter installed as standard.

See ServerProven® at the following web address for the latest information about the expansion cards that are supported by each blade server type:
http://ibm.com/servers/eserver/serverproven/compat/us/

I/O adapter cards are installed in the slot in supported servers, such as the x240, as highlighted in the following figure.

Supported I/O modules

These adapters can be installed in any I/O adapter slot of a supported Flex System compute node. Two compatible I/O modules must be installed in the chassis to enable both ports of the adapter. The following table lists the switches that are supported.

When connected to the EN2092 1Gb Ethernet Scalable Switch, the internal switch ports will operate at 1 Gb speeds.
