The Mellanox MCX75310AAS NEAT ConnectX 7 IB NDR400 InfiniBand network adapter card is a high performance networking component designed for high speed data transfer in data centers, high performance computing (HPC), and enterprise environments. Here's an overview of its key features:

1. Introduction:

  The Mellanox ConnectX 7 IB NDR400 is part of the ConnectX 7 family, which is known for its advanced features and high speed connectivity options.

  It is designed to support the InfiniBand (IB) NDR (Non Data Rate) 400Gb/s standard, which is a high speed interconnect technology used for connecting servers, storage, and other devices in a network.

2. Speed:

  The card supports data transfer speeds up to 400 Gb/s, which is equivalent to 50 Gbps, providing ultra fast data transfer capabilities.

3. Interface Type:

  The card uses the InfiniBand interface, which is a switched fabric network technology that provides high throughput and low latency communication between devices.

4. Hardware Interface:

  The ConnectX 7 IB NDR400 card features a QSFP DD (Quad Small Form factor Pluggable Double Density) connector, which is a high density optical interface that supports multiple 100Gb/s channels over a single fiber.

  It also supports EDR (Enhanced Data Rate) 100Gb/s InfiniBand, providing backward compatibility with existing EDR infrastructure.

5. Chip Type:

  The card is powered by Mellanox's BlueField 2 SoC (System on Chip), which is a high performance, multi core processor designed for networking and storage applications.

  The BlueField 2 SoC includes advanced features such as hardware based security, virtualization, and acceleration for various network functions.

6. System Compatibility:

  The card is designed to work with a variety of operating systems, including Linux, Windows, and other Unix based systems.

  It is also compatible with Mellanox's OFED (OpenFabrics Enterprise Distribution) software, which provides support for InfiniBand and RoCE (RDMA over Converged Ethernet) networking.

7. Additional Features:

  The card supports RDMA (Remote Direct Memory Access), which allows for direct memory access from one computer to another without involving the operating system, reducing latency and improving performance.

  It also supports various network protocols, including TCP/IP, UDP, and SCST (SCSI over Converged Ethernet).

8. Power Consumption and Cooling:

  The card is designed to be energy efficient, with advanced power management features to reduce power consumption.

  It includes active cooling mechanisms to ensure optimal performance and prevent overheating during high load operations.

The Mellanox MCX75310AAS NEAT ConnectX 7 IB NDR400 is a cutting edge networking solution that offers high speed data transfer, advanced features, and compatibility with a wide range of systems and applications. It is an excellent choice for organizations that require high performance networking capabilities for their data centers and HPC environments.
