Product Overview

100Gb/s InfiniBand & Ethernet Adapter Card

ConnectX-6 Virtual Protocol Interconnect® (VPI) cards are a groundbreaking addition to the Mellanox ConnectX series of industry-leading adapter cards. Providing 100Gb/s for InfiniBand and Ethernet connectivity, ConnectX-6 VPI cards enable the highest performance and most flexible solution aimed at meeting the continually growing demands of data centre applications. In addition to all the existing innovative features of past versions, ConnectX-6 cards offer a number of enhancements to further improve performance and scalability.

ConnectX-6 VPI cards supports HDR100, EDR, FDR, QDR, DDR and SDR InfiniBand speeds as well as 100, 50, 40, 25, and 10 Gb/s Ethernet speeds.

HPC Environments

Over the past decade, Mellanox has consistently driven HPC performance to new record heights. With the introduction of the ConnectX-6 adapter card, Mellanox continues to pave the way with new features and unprecedented performance for the HPC market.

ConnectX-6 VPI delivers the highest throughput and message rate in the industry. As the first adapter to deliver 100Gb/s HDR InfiniBand, 100Gb/s HDR100 InfiniBand and 100Gb/s Ethernet speeds, ConnectX-6 VPI is the perfect product to lead HPC data centres toward Exascale levels of performance and scalability.

ConnectX-6 supports the evolving co-design paradigm, which transforms the network into a distributed processor. With its In-Network Computing and In-Network Memory capabilities, ConnectX-6 offloads computation even further to the network, saving CPU cycles and increasing network efficiency.

ConnectX-6 VPI utilises both IBTA RDMA (Remote Direct Memory Access) and RoCE (RDMA over Converged Ethernet) technologies, delivering low-latency and high performance. ConnectX-6 enhances RDMA network capabilities even further by delivering end-to-end packet level flow control.

Machine Learning and Big Data Environments

Data analytics has become an essential function within many enterprise data centres, 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 100Gb/s throughput, ConnectX-6 is the perfect solution to provide machine learning applications with the levels of performance and scalability that they require.

ConnectX-6 utilises 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.


The 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. ConnectX-6 hardware offloads the IEEE AES-XTS encryption/decryption from the CPU, saving latency and CPU utilisation. It also guarantees protection for users sharing the same resources through the use of dedicated encryption keys.

By performing block-storage encryption in the adapter, ConnectX-6 excludes the need for self-encrypted disks. This allows customers the freedom to choose their preferred storage device, including byteaddressable and NVDIMM devices that traditionally do not provide encryption. Moreover, ConnectX-6 can support Federal Information Processing Standards (FIPS) compliance.

ConnectX-6 also includes a hardware Root-of-Trust (RoT) that uses HMAC relying on a device-unique key. This provides both secure boot as well as cloning protection. Delivering best-in-class device and firmware protection, ConnectX-6 also provides secured debugging capabilities, without the need for physical access.

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 optimisation to NVMe-oF, enhancing CPU
utilisation and scalability.

Cloud and Web 2.0 Environments

Telco, 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 utilisation of available CPU for compute functions.

To address such performance issues, ConnectX-6 offers Mellanox ASAP2 - Accelerated Switch and Packet Processing® technology. ASAP2 offloads 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 minus 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.

Wide Selection of Smart Adapters

Providing up to 100Gb/s InfiniBand or Ethernet connectivity, ConnectX-6 VPI Smart Adapters are available in two form factors: low-profile stand-up PCIe and OCP3.0 cards with QSFP connectors. The ConnectX-6 VPI portfolio also provides options for Mellanox Socket Direct® configurations.

• Up to 100Gb/s connectivity per port.
• Max bandwidth of 100Gb/s.
• Block-level XTS-AES mode hardware encryption.
• FIPS capable.
• Advanced storage capabilities including block-level encryption and checksum offloads.
