Features
The Mellanox ConnectX-6 Dx 100GbE QSFP56 Ethernet Adapter offers a number of features, including the
following:

ThinkSystem Mellanox ConnectX-6 Dx 100GbE QSFP56 Ethernet Adapter 3

Security to every end-point
In an era where privacy of information is key and zero trust is the rule, ConnectX-6 Dx adapters offer a
range of advanced built-in capabilities that bring security down to the end-points with unprecedented
performance and scalability, including:
Probes & DoS Attacks Protection – ConnectX-6 Dx enables a hardware-based L4 firewall by ASAP2
offloading of stateful connection tracking.
NIC Security – Hardware Root-of-Trust (RoT) Secure Boot and secure firmware update using RSA
cryptography, and cloning-protection, via a device-unique secret key.

Advanced virtualization
ConnectX-6 Dx delivers another level of innovation to enable building highly efficient virtualized cloud data
centers:
Virtualization – Mellanox ASAP2 - Accelerated Switch and Packet Processing® technology for
vSwitch/vRouter hardware offload, delivers orders of magnitude higher performance vs. software-
based solutions. ConnectX-6 Dx ASAP2 offers both SR-IOV and VirtIO in-hardware offload
capabilities, and supports up to 8 million rules.
Advanced Quality of Service – Includes traffic shaping, and classification-based data policing.

Industry-leading RoCE
Following the Mellanox ConnectX tradition of industry-leading RoCE capabilities, ConnectX-6 Dx adds
another layer of innovation to enable more scalable, resilient and easy-to-deploy RoCE solutions.
Zero Touch RoCE – Simplifying RoCE deployments ConnectX-6 Dx allows RoCE payloads to run
seamlessly on existing networks without requiring special configuration on the network (no PFC, no
ECN). ConnectX-6 Dx’s features ensure resiliency and efficiency at scale of such deployments.
Configurable Congestion Control – API to build user-defined congestion control algorithms, best
serving various environments and RoCE and TCP/IP traffic patterns.

Efficient storage solutions

With its NVMe-oF target and initiator offloads, ConnectX-6 Dx brings further optimization to NVMe-oF,
enhancing CPU utilization and scalability. Additionally, ConnectX-6 Dx supports hardware offload for
ingress/egress of T10-DIF/PI/CRC32/CRC64 signatures thereby enabling user-based key management and
a one-time-FIPS-certification approach.
