The Flex System™ EN6132 2-port 40Gb Ethernet Adapter in conjunction with the EN6132 40Gb Ethernet Switch offers the performance that you need to support clustered databases, parallel processing, transactional services, and high-performance embedded I/O applications, which reduces task completion time and lowers the cost per operation. The EN6132 adapter can help you achieve efficient computing by offloading (from the CPU) protocol processing and data movement impact, such as RDMA over Converged Ethernet and Send/Receive semantics, which allows more processor power for the application.

Did you know?
The 40 Gb Ethernet solution that is offered by Flex System can deploy more workloads per server without running into I/O bottlenecks. If there are failures or server maintenance, clients can move their virtual machines much faster by using 40 Gb interconnects within the chassis.
The 40 GbE switch and adapter are designed for low latency, high bandwidth, and computing efficiency for performance-driven server and storage clustering applications. They provide extreme scalability for low-latency clustered solutions with reduced packet hops.
The Flex System 40 GbE solution offers the highest bandwidth without adding any significant power impact. It can also help increase the system usage and decrease the number of network ports for further cost savings.

Supported I/O modules
The EN6132 2-port 40Gb Ethernet Adapter supports the I/O modules that are listed in Table 3.
Table 3. Supported I/O modules
|Description||Part number||Feature code|
(x-config / e-config)
|Flex System EN6131 40Gb Ethernet Switch||90Y9346||A3HJ / ESW6|
Other I/O modules: Other I/O modules that are not listed in Table 3 are not supported.
The supported I/O modules are installed in the I/O bays in the rear of the Flex System Enterprise Chassis, as shown in Figure 2.
Figure 2. Location of the I/O module bays in the Flex System Enterprise Chassis
The connections between the EN6132 adapters that are installed in the compute nodes to the supported I/O modules that are installed in the chassis I/O bays are shown in Figure 3. The figure also shows both half-wide compute nodes, such as the x240 with two adapters, and full-wide compute nodes, such as the x440 with four adapters.
Figure 3. Logical layout of the interconnects between EN6132 adapters and I/O modules
The EN6131 2-port 40Gb Ethernet Adapter can be installed in slots A1 and A2 of the half-wide compute nodes (such as x240), and slots A1, A2, A3, and A4 of the full-wide compute nodes (such as x440). A supported Ethernet I/O module must be installed in the corresponding I/O bay of the chassis (bays 1 and 2 when the adapter is installed slot A1 or A3 or bays 3 and 4 when the adapter is installed in slot A2 or A4).
In the compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC), NIC ports are routed to bays 1 and 2 with a specialized periscope connector, and the adapter in slot A1 is not required. However, when needed, the periscope connector can be replaced with the EN6132 adapter. In such a case, integrated NIC is disabled.
Table 4 shows the connections between the EN6132 adapters that are installed in the compute nodes to the supported I/O modules that are installed in the chassis.

|Port on the adapter||Corresponding I/O module bay in the chassis|
