Flex System EN2024 4-port 1Gb Ethernet Adapter

The Flex System™ EN2024 4-port 1Gb Ethernet Adapter is a quad-port Gigabit Ethernet network adapter. When it is combined with the Flex System EN2092 1Gb Ethernet Scalable Switch, clients can leverage an end-to-end 1 Gb solution on the 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.

Figure 1. Flex System EN2024 4-port 1Gb Ethernet Adapter

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

Table 2. Supported servers

Description	Part number
Flex System EN2024 4-port 1Gb Ethernet Adapter	49Y7900	Y	N	Y	Y	Y	Y	Y	Y	Y*	Y*

* Only supported in slots 1 and 2 of the x280 X6, x480 X6, and x880 X6

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.

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

These adapter can be installed in any I/O adapter slot of a supported Flex System compute node. One or two compatible 1 Gb or 10 Gb I/O modules must be installed in the corresponding I/O bays in the chassis. The following table lists the switches that are supported. When connected to the 10Gb switch or pass-thru module, the internal switch ports will operate at 1Gb speeds.

To maximize the number of adapter ports usable, you may also need to order switch upgrades to enable additional ports as listed in the table. Alternatively, for CN4093, EN4093R, and SI4093 switches, you can use Flexible Port Mapping, a new feature of Networking OS 7.8, that allows you to minimize the number of upgrades needed. See the Product Guides for the switches for more details:
http://lenovopress.com/flexsystem/iomodules

The table also specifies how many ports of the adapter are supported once the indicated upgrades are applied. Switches should be installed in pairs to maximize the number of ports enabled and to provide redundant network connections.

Table 3. I/O modules and upgrades for use with the EN2024 4-port 1Gb Ethernet Adapter

* This column indicates the number of adapter ports that will be active if indicated upgrades are installed.

The adapter does not support the following I/O modules:

• Flex System EN6131 40Gb Ethernet Switch

The following table shows the connections between adapters installed in the compute nodes to the switch bays in the chassis.

* Ports 3 and 4 require Upgrade 1 of either the EN2092 1Gb or EN4093 10Gb switch. The EN4091 Pass-thru only supports ports 1 and 2 (and only when two I/O modules are installed).

The connections between the adapters installed in the compute nodes to the switch bays in the chassis are shown diagrammatically in the following figure. The figure shows both half-wide servers, such as the x240 with two adapters, and full-wide servers, such as the x440 with four adapters.
