MCX6xx ConnectX®-6 EN single/dual-port adapter supporting 200Gb/s ethernet On Request On Request

Intelligent ConnectX-6 adapter cards are part of the Mellanox Smart Interconnect suite and support Co-Design and In-Network Compute. They introduce new acceleration engines for maximising Cloud, Web 2.0, Big Data, Storage, and Machine Learning applications. 

ConnectX-6 EN supports two ports of 200Gb/s Ethernet connectivity, sub-600 nanosecond latency, and 200 million messages per second, providing the highest performance and most flexible solution for the most demanding applications and markets. It offers Mellanox Accelerated Switching And Packet Processing (ASAP2) Direct 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. 

This product also offers a crucial innovation to network security by providing block-level encryption. Data in transit undergoes encryption and decryption as it is stored or retrieved. The encryption/decryption is offloaded by the ConnectX-6 hardware, saving latency and offloading CPU. ConnectX-6 block-level encryption offload enables protection between users sharing the same resources, as different encryption keys can be used. 

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 to deliver 200Gb/s throughput, ConnectX-6 is the perfect solution to provide machine learning applications with the levels of performance and scalability that they require.
