Zero-Trust Security

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 endpoints with unprecedented performance and scalability, including:

• Crypto – IPsec and TLS data-in-motion inline encryption and decryption offload, and AES-XTS block-level data-at-rest encryption and decryption offload.

• Probes & DoS Attack Protection – ConnectX-6 Dx enables a hardware-based L4 firewall by offloading stateful connection tracking through Mellanox ASAP2 - Accelerated Switch and Packet Processing®.

• 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 Vistualization

ConnectX-6 Dx delivers another level of innovation to enable building highly efficient virtualized cloud data centers:

• Virtualization – Mellanox ASAP2 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). New features in ConnectX-6 Dx 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.

Best-In-Class PTP For Time Sensitive Application

Mellanox offers a full IEEE 1588v2 PTP software solution as well as time sensitive related features called 5T45G. Mellanox PTP and 5T45G software solutions are designed to meet the most demanding PTP profiles. ConnectX-6 Dx incorporates an integrated Hardware Clock (PHC) that allows the device to achieve sub-20 usec accuracy while offering various timing related functions, including time-triggered scheduling or time-based SNDaccelerations (time based ASAP²). Furthermore, 5T45G technology enables software applications to transmit front-haul (ORAN) compatible in high bandwidth. The PTP solution supports slave clock, master clock, and boundary clock.

Selected ConectX-6 Dx SmartNICs provide PPS-Out or PPS-In signals from designated SMA connectors.

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, as well as AES-XTS encryption/decryption offload enabling user-based key management and a one-time-FIPS-certification approach.

Wide Selection of NICs

ConnectX-6 Dx SmartNICs are available in several form factors including low-profile PCIe, OCP2.0 and OCP3.0 cards, with various network connector types (SFP28/56, QSFP28/56, or DSFP). The ConnectX-6 Dx portfolio also provides options for Mellanox Multi-Host® and Mellanox Socket Direct® configurations.

Mellanox Multi-Host® connects multiple compute or storage hosts to a single interconnect adapter and enables designing and building new scale-out compute and storage racks. This enables better power and performance management, while reducing capital and operational expenses.

Mellanox Socket Direct® technology brings improved performance to multi-socket servers, by enabling each CPU in a multi-socket server to directly connect to the network through its dedicated PCIe interface. This enables data to bypass the QPI (UPI) and the other CPU, improving latency, performance and CPU utilization.
