The "MCX555A ECAT ConnectX 5 VPI adapter card EDR IB (100Gb/s) and 100GbE dual port QSFP28 PCIe4.0 x16 tall bracket" is a high performance networking component designed for data intensive applications such as high frequency trading, big data analytics, and supercomputing. Here's a breakdown of its key features:

1. Introduction:

  The MCX555A ECAT is a part of the ConnectX 5 family of adapters, known for their high speed data transfer capabilities and advanced networking features. It is designed to support the latest Ethernet standards and InfiniBand (IB) protocols, providing a robust solution for demanding environments.

2. Speed:

  The card supports both 100Gb/s InfiniBand EDR (Enhanced Data Rate) and 100GbE (Ethernet), which means it can handle data transfer rates of up to 100 gigabits per second. This high speed is crucial for applications that require real time processing and analysis of large data sets.

3. Interface Type:

  The card features a dual port QSFP28 interface, which is a compact, hot pluggable optical transceiver that supports 100GbE and InfiniBand EDR. QSFP28 transceivers are designed to be backward compatible with QSFP+ and QSFP interfaces, providing flexibility in network upgrades.

4. Hardware Interface:

  The card is equipped with a PCIe 4.0 x16 interface, which is the latest generation of the PCIe standard. This interface allows for high speed communication between the adapter card and the host system, ensuring that the card can keep up with the demands of high speed networking.

5. Chip Type System:

  The ConnectX 5 family of adapters is powered by the BlueField 2 SoC (System on Chip), which is a multi core processor designed specifically for networking and storage applications. The BlueField 2 SoC provides advanced features such as hardware based security, virtualization, and acceleration for various networking tasks.

6. Additional Features:

  The tall bracket design of the card allows for better airflow and cooling in high density server racks, which is essential for maintaining performance in environments with multiple high speed networking cards.

  The card also supports various virtualization technologies, enabling the creation of multiple virtual network interfaces on a single physical card, which can be useful for cloud computing and network function virtualization (NFV) applications.

In summary, the MCX555A ECAT ConnectX 5 VPI adapter card is a high performance networking solution that combines the speed of 100Gb/s InfiniBand EDR and 100GbE with the flexibility of a dual port QSFP28 interface and the power of the BlueField 2 SoC. It is designed to meet the demands of the most data intensive applications and is a key component in modern high speed networking infrastructures.
