IBM Flex System CN4022 2-port 10Gb Converged Adapter

IBM Redbooks Product Guide

Abstract

The IBM® Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network adapter that supports Ethernet, Fibre Channel over Ethernet (FCoE), and Internet Small Computer System Interface (iSCSI) protocols out of the box. Clients now have a choice of multiple vendors without compromising the features. This adapter also supports virtual network interface controller (vNIC) capability, which helps clients reduce cost and complexity. The CN4022 adapter is based on the Broadcom 57840 controller and offers a PCIe 2.0 x8 host interface. This IBM Redbooks® Product Guide describes the IBM Flex System CN4022 2-port 10Gb Converged Adapter.

Changes in the March 21 update:
* The adapter currently does not support 1 Gb traffic and is not supported with the EN2092 1Gb Ethernet Scalable Switch

Introduction

The IBM® Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network adapter that supports Ethernet, Fibre Channel over Ethernet (FCoE), and Internet Small Computer System Interface (iSCSI) protocols out of the box. Clients now have a choice of multiple vendors without compromising the features. This adapter also supports virtual network interface controller (vNIC) capability, which helps clients reduce cost and complexity. The CN4022 adapter is based on the Broadcom 57840 controller and offers a PCIe 2.0 x8 host interface. This IBM Redbooks® Product Guide describes the IBM Flex System CN4022 2-port 10Gb Converged Adapter.

The CN4022 2-port 10Gb Converged Adapter is shown in the following figure.

Did you know?

This CN4022 is based on the industry-standard PCIe architecture and is ideal for clients that use 10 GbE in their network infrastructure and that 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 virtual NICs (vNICs).
