SKU: MCX613106A-VDAT Category:


World’s first 200GbE Ethernet network interface card, enabling industry-leading performance smart offloads and in-network computing for Cloud, Web 2.0, Big Data, Storage and Machine Learning applications.

ConnectX-6 EN provides up to two ports of 200GbE connectivity, sub 0.8usec latency and 215 million messages per second, enabling the highest performance and most flexible solution for the most demanding data center applications.

ConnectX-6 is a groundbreaking addition to the Mellanox ConnectX series of industry-leading adapter cards. In addition to all the existing innovative features of past versions, ConnectX-6 offers a number of enhancements to further improve performance and scalability, such as support for 200/100/50/40/25/10/1 GbE Ethernet speeds and PCIe Gen 4.0. Moreover, ConnectX-6 Ethernet cards can connect up to 32-lanes of PCIe to achieve 200Gb/s of bandwidth, even on Gen 3.0 PCIe systems.

For Cloud and Web 2.0 Environments

Cloud and Web 2.0 customers developing their platforms on Software Defined Network (SDN) environments are leveraging the Virtual Switching capabilities of the Operating Systems on their servers to enable maximum flexibility in the management and routing protocols of their networks.

Open vSwitch (OVS) is an example of a virtual switch that allows Virtual Machines to communicate among themselves and with the outside world. Software-based virtual switches, traditionally residing in the hypervisor, are CPU intensive, affecting system performance and preventing full utilization of available CPU for compute functions. To address this, ConnectX-6 offers ASAP2 – Mellanox Accelerated Switch and Packet Processing®technology to offload the vSwitch/vRouter by handling the data plane in the NIC hardware while maintaining the control plane unmodified. As a result, significantly higher vSwitch/vRouter performance is achieved without the associated CPU load.

The vSwitch/vRouter offload functions supported by ConnectX-5 and ConnectX-6 include encapsulation and de-capsulation of overlay network headers, as well as stateless offloads of inner packets, packet headers re-write (enabling NAT functionality), hairpin and more.

In addition, ConnectX-6 offers intelligent flexible pipeline capabilities, including programmable flexible parser and flexible match-action tables, which enable hardware offloads for future protocols.

For Storage Environments

NVMe storage devices are gaining momentum, offering very fast access to storage media. The evolving NVMe over Fabric (NVMe-oF) protocol leverages RDMA connectivity to remotely access NVMe storage devices efficiently, while keeping the end-to-end NVMe model at lowest latency. With its NVMe-oF target and initiator offloads, ConnectX-6 brings further optimization to NVMe-oF, enhancing CPU utilization and scalability.

ConnectX-6 block-level encryption offers a critical innovation to network security. As data in transit is stored or retrieved, it undergoes encryption and decryption. The ConnectX-6 hardware offloads the IEEE AES-XTS encryption/decryption from the CPU, saving latency and CPU utilization. It also guarantees protection for users sharing the same resources through the use of dedicated encryption keys.


Machine Learning and Big Data Environments

Data analytics has become an essential function within many enterprise data centers, clouds and hyperscale platforms. Machine learning relies on especially high throughput and low latency to train deep neural networks and to improve recognition and classification accuracy. As the first adapter card to deliver 200GbE throughput, ConnectX-6 is the perfect solution to provide machine learning applications with the levels of performance and scalability that they require. ConnectX-6 utilizes the RDMA technology to deliver low-latency and high performance. ConnectX-6 enhances RDMA network capabilities even further by delivering end-to-end packet level flow control.
