IBM Flex System EN2024 4-port 1Gb Ethernet Adapter

IBM Redbooks Product Guide

The IBM Flex System™ EN2024 4-port 1Gb Ethernet Adapter is a quad-port Gigabit Ethernet network 
adapter. When it is combined with the IBM Flex System EN2092 1Gb Ethernet Scalable Switch, clients 
can leverage an end-to-end 1 Gb solution on the IBM Flex System Enterprise Chassis. The EN2024 
adapter is based on the Broadcom 5718 controller and offers a PCIe 2.0 x1 host interface with 
MSI/MSI-X. It also supports I/O virtualization features like VMware NetQueue and Microsoft VMQ 
technologies.

Figure 1 shows the adapter.

Did you know?

This EN2024 is based on the industry-standard PCIe architecture and is ideal for customers using Gigabit 
Ethernet in their network infrastructure. The IBM Flex System compute nodes support up to two of these 
adapters for a total of eight NICs per system.
