The adapter, when shipped as a stand-alone option, includes the following items:

One Mellanox ConnectX-5 Ex EN adapter
Two QSFP28 to SFP28 transceiver adapters (QSA28)
Full-height (3U) bracket attached with low-profile (2U) bracket included in the box
Documentation flyer

QSA28 adapters: The option part number includes the QSA28 adapters, however when ordering the adapter as part of a server CTO build, the feature code B31C does not include the adapters and they must be ordered separately.

Supported transceivers and cables

The adapter has two empty QSFP28 cages. The adapter also includes two QSA28 adapters that convert the QSFP28 cages to SFP28 for 25Gb connectivity.
The adapter either supports a connection to a 1Gb, 10Gb, 25Gb or 40Gb switch or can share a connection to a 100Gb switch using a 4:1 breakout cable.
The following table lists the supported transceivers.

Table 2. Transceivers

Part number	Feature code	Description

Two QSA adapters are included with the ConnectX-5 Ex adapter part number, however they are not included with the adapter when ordered with a server as part of a CTO build. For CTO orders, select the QSA adapters separately if needed.
† This 25 Gb transceiver also supports 10 Gb when used with a Mellanox adapter

25Gb transceivers: When installed in this 25Gb Ethernet adapter, certain supported 25Gb transceivers (as listed in the above table) are designed to operate at either 25 Gb/s or 10 Gb/s speeds, depending on the negotiation with the connected switch. In most configurations, this negotiation is automatic, however in some configurations you may have to manually set the link speed or FEC mode.

Features

The ThinkSystem Mellanox ConnectX-5 Ex 25/40GbE 2-port Low-Latency Adapter has the following key features:
Ultra-low latency
Mellanox ConnectX-5 adapter cards feature exceedingly low latency and hardware-based RDMA technology that is perfect for meeting the needs of the financial services industry. Based on advanced technology providing sub- microsecond latency and a capacity of 200 million messages per second, ConnectX-5 offers the next generation of connectivity today.
Mellanox’s Messaging Accelerator (VMA) transparently boosts performance for socket-based applications without having to modify the applications. By offloading network processing from the OS, traffic passes directly to the network adapter from the application user space, bypassing the kernel IP stack and minimizing context switches, buffer copies, and interrupts. The result is a reduction in latency by 500% and an increase in application throughput, as compared to applications running on a standard network kernel stack.
Cloud, SDN, and NFV environment support
Mellanox Accelerated Switching and Packet Processing (ASAP2) Direct technology allows to offload vSwitch/vRouter by handling the data plane in the NIC hardware while maintaining the control plane unmodified. As a result there is significantly higher vSwitch/vRouter performance without the associated CPU load
The vSwitch/vRouter offload functions that are supported by ConnectX-5 include Overlay Networks (for example, VXLAN, NVGRE, MPLS, GENEVE, and NSH) headers’ encapsulation and de-capsulation, as well as stateless offloads of inner packets, packet headers’ re-write enabling NAT functionality, and more.
Moreover, the intelligent ConnectX-5 flexible pipeline capabilities, which include flexible parser and flexible match-action tables, can be programmed, which enable hardware offloads for future protocols.
ConnectX-5 SR-IOV technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines (VMs) within the server. With ConnectX-5 Network Function Virtualization
(NFV), a VM can be used as a virtual appliance. With full data-path operations offloads as well as hairpin hardware capability and service chaining, data can be handled by the Virtual Appliance with minimum CPU utilization.
With these capabilities data center administrators benefit from better server utilization while reducing cost, power, and cable complexity, allowing more Virtual Appliances, Virtual Machines and more tenants on the same hardware.
