The Mellanox MCX653106A EFAT is a high performance network adapter card designed for data centers and high performance computing (HPC) environments. Here's an overview of its key features:

1. Introduction:

  The Mellanox MCX653106A EFAT is part of the Mellanox ConnectX? 6 series, which is known for its advanced performance and efficiency in Ethernet and InfiniBand networks.

2. Speed:

  This adapter card supports speeds up to 200 Gbps (100 Gb/s per port) using Mellanox's proprietary technology, which can be configured for different speeds depending on the network fabric requirements.

3. Interface Type:

  It provides dual port 100GbE (100 Gigabit Ethernet) connectivity, which can be used for both Ethernet and InfiniBand networks, thanks to Mellanox's support for both protocols on the same hardware.

4. Hardware Interface:

  The card features PCIe 4.0 (PCI Express 4.0) interface, which is backward compatible with PCIe 3.0 and 2.0, allowing for flexibility in different server configurations.

5. Chip Type System:

  The ConnectX 6 series, including the MCX653106A EFAT, is based on Mellanox's BlueField SoC (System on Chip), which integrates a powerful ARM processor with the network interface. This allows for advanced offloading capabilities, including RDMA (Remote Direct Memory Access), which can significantly reduce latency and increase throughput in data transfers.

6. Additional Features:

  RDMA over Converged Ethernet (RoCE): Supports RDMA over Ethernet, which is crucial for high performance computing and storage applications.

  VPI (Virtual Protocol Interconnect): Enables the creation of multiple virtual interfaces on a single physical port, increasing flexibility and efficiency in virtualized environments.

  Energy Efficient: Mellanox adapters are known for their low power consumption, which is beneficial for data centers looking to reduce energy costs.

  Spectrum: Mellanox's advanced software suite that provides a range of features for network management, performance monitoring, and security.

Please note that specific details such as the exact model number, firmware version, and other technical specifications can vary, and it's always recommended to check the latest datasheets or product documentation from Mellanox for the most accurate and up to date information.
