The Mellanox MCX653106A HDAT SP ConnectX 6 Dx EN Fiber Optic NIC is a high performance network interface card (NIC) designed for high speed data transmission in data centers and high performance computing environments. Here's an overview of its key features:

1. Introduction:

  The Mellanox ConnectX 6 Dx EN is a part of the ConnectX 6 family of adapters, which are known for their advanced networking capabilities and high speed data transfer rates. The Dx EN variant is specifically designed for Ethernet networking.

2. Speed:

  The card supports 100GbE (100 Gigabit Ethernet) speeds, which is suitable for applications requiring high bandwidth and low latency.

3. Interface Type:

  It features QSFP (Quad Small Form factor Pluggable) ports, which are commonly used for 40GbE and 100GbE applications. The "56 Dual Optical Ports" mentioned in the product name suggests that it has 56 fiber optic ports, which is an unusually high number for a single NIC and might be a typo or a specific configuration for a particular use case.

4. Hardware Interface:

  The card is designed to work with PCIe (Peripheral Component Interconnect Express) interfaces, which are the standard high speed expansion slots found in modern servers and workstations. The specific PCIe generation is not specified in the product name, but it is likely to be compatible with PCIe Gen 4.0 or higher for achieving the full 100GbE speed.

5. Chip Type System:

  Mellanox ConnectX 6 Dx EN cards are based on Mellanox's BlueField SoC (System on Chip) architecture, which integrates multiple high speed networking interfaces along with advanced processing capabilities. The BlueField SoC is designed to offload network processing tasks from the host CPU, improving overall system performance and efficiency.

6. Additional Features:

  The card likely supports various advanced networking features such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), which allows for low latency and high throughput data transfer between servers.

  It may also support virtualization technologies, enabling multiple virtual machines to share the NIC and its resources.

  Security features, such as hardware based encryption and decryption, may also be included to protect data in transit.

Please note that the specific details such as the exact number of ports and the compatibility with certain systems or software would require checking the latest product documentation or contacting Mellanox directly for the most accurate and up to date information.
