Mellanox NVIDIA CONNECTX-6 200G InfiniBand/Ethernet VPI Adapter Cards

NVIDIA Quantum InfiniBand platform relies on ConnectX6 InfiniBand smart adapter cards. ConnectX6 provides 200Gbps Fast Ethernet and InfiniBand connectivity with extremely low latencies, high message rates, smart offloads and acceleration from NVIDIA In-Network Computing.

KEY FEATURES

• Up to 200Gb/s Max bandwidth connectivity per port
• Up to 215 million messages/sec with extremely low latency
• XTS-AES mode hardware encryption at the block level
• Compliant with FIPS (Federal Information Processing Standards)
• SerDes (PAM4) and SerDes (NRZ) both are supported
• Excellent packet pacing with sub-nanosecond accuracy
• Support for PCIe Gen 3.0 and Gen 4.0
• Engines for accelerating in-network computation
• Open Data Center Committee (ODCC) compatible and RoHS-compliant

PRODUCT SPECIFICATION

ConnectX-6 supports NVIDIA In-Network Computing and In-Network Memory, offloading computation to the network to save CPU time and increase efficiency. InfiniBand Trade Association (IBTA) specification defines remote direct memory access (RDMA) technology that delivers low latency and high performance. It provides end-to-end packet-level flow control to enhance RDMA network capabilities.

Big Data and Machine Learning

Clouds, hyperscale platforms, and enterprise data centers increasingly use data analytics. To train deep neural networks (DNNs) and improve recognition and classification accuracy, machine learning requires high throughput and low latency. ConnectX-6 provides ML applications with the performance and scalability they need with its 200Gb/s throughput.

Encryption and Security

ConnectX-6 block-level encryption improves network security. AES-XTS encryption/decryption is offloaded from the CPU to ConnectX-6 hardware, which saves CPU time and utilization. With dedicated encryption keys, it also protects users sharing the same resources. It replaces self-encrypted disks with block storage encryption in the adapter. With this, you can choose any device you want, including byte addressable and NVDIMMs that are traditionally not encrypted. Moreover, ConnectX-6 can comply with Federal Information Processing Standards (FIPS).

NVMe-oF for storage

The access time to storage media is very fast with NVMe storage devices. In order to provide low latency end-to-end NVMe storage devices remotely, the NVMe over Fabric (NVMe-oF) protocol leverages RDMA connectivity. Enhanced CPU utilization and scalability are achieved by ConnectX-6's NVMe-oF target and initiator offloads. 

OTHER INTERFACES 

Adapters with smart features

The ConnectX-6 series is available in two form factors: a low-profile stand-up PCIe card and a QSFP card with Open Compute Project specification 3.0. Stand-up PCIe adapters with HDR are available from ConnectX-6 or ConnectX-6 DE (ConnectX-6 Dx enhanced for HPC applications). Additionally, PCIe stand-up cards with cold plates are available for liquid-cooled Intel Server System D50TNP systems.

NVIDIA Socket Direct

A NVIDIA Socket Direct configuration improves the performance of multi-socket servers by allowing each CPU to access the network using its own PCIe interface. This improves latency, performance, and CPU utilization by bypassing the QPI (UPI) and other CPUs. With Socket Direct, GPUs are also linked to CPUs closest to the adapter cards via NVIDIA GPUDirect RDMA. It is possible to optimize Intel DDIO on both sockets with Socket Direct since the sockets and adapter cards are connected directly. An auxiliary PCIe card brings in the remaining PCIe lanes through Socket Direct technology. It is installed in two PCIe x16 slots and connected with a harness. Additionally, two PCIe x16 slots can be connected to the same CPU. Its main advantage lies in delivering 200Gb/s to servers that only support PCIe Gen3.
Host Management

NC-SI over MCTP over SMBus, MCTP via PCIe to BMC interfaces, and PLDM for both Monitor and Control DSP0248 and Firmware Update DSP0267 form part of Host Management.
