Lenovo Flex System CN4022 2-port 10Gb Converged Adapter User Guide

Lenovo Flex System CN4022 2-port 10Gb Converged Adapter User Guide

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://www.lenovo.com/us/en/serverproven/flexsystem.shtml I/O adapter cards are installed in the slot in supported servers, such as the x240,as highlighted in the following figure.

Figure 2. Location of the I/O adapter slots in the Flex System x240 Compute Node

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. When connected to the NE2552E 25Gb Switch, the internal switch ports will operate at 10 Gb speeds.
