The Mellanox Connectx-5 EN Ethernet Card PCI-E 2 Ports Adapter, also known as MCX516A-GCAT, is a powerful network adapter designed for high-performance computing environments. It is a product of Mellanox Technologies, a leading provider of networking solutions for data centers, cloud computing, and high-performance computing (HPC) systems. This Ethernet card provides two 25 Gigabit Ethernet (GbE) ports and is compatible with PCI-Express 3.0 x16 slots. In this article, we will discuss the key features and benefits of MCX516A-GCAT.
Key FeaturesThe MCX516A-GCAT Mellanox Connectx-5 EN Ethernet Card Pci-E 2 Ports Adapter has several key features that make it a powerful networking solution for HPC systems.
ConnectX-5 EN Ethernet Controller: The MCX516A-GCAT is built around Mellanox's ConnectX-5 EN Ethernet controller, which is specifically designed to provide high-performance networking for HPC environments. This controller supports RDMA over Converged Ethernet (RoCE), which allows for low-latency and high-bandwidth communication between nodes in a cluster.
PCI-Express 3.0 x16 Interface: The MCX516A-GCAT is designed to be used with PCI-Express 3.0 x16 slots, which provide high-bandwidth connectivity to the system's CPU and memory. This ensures that the network adapter does not become a bottleneck in the system's overall performance.
Two 25GbE Ports: The MCX516A-GCAT provides two 25GbE ports, which are compatible with SFP28 optical modules. These ports can be used to connect to other nodes in a cluster or to connect to high-speed storage devices.
Low Power Consumption: The MCX516A-GCAT is designed to be energy-efficient, with a typical power consumption of only 11 watts per port. This makes it an ideal choice for HPC systems that require high-performance networking but also need to minimize power consumption.
Benefits of MCX516A-GCATHigh Performance: The MCX516A-GCAT provides high-performance networking capabilities for HPC systems. Its ConnectX-5 EN Ethernet controller supports RoCE, which provides low-latency and high-bandwidth communication between nodes in a cluster. The two 25GbE ports provide high-speed connectivity to other nodes or storage devices, ensuring that the network does not become a bottleneck in the system's overall performance.
Scalability: The MCX516A-GCAT is designed to be scalable, with support for up to 100GbE throughput. This allows it to be used in large-scale HPC environments where high-performance networking is critical.
Energy Efficiency: The MCX516A-GCAT is designed to be energy-efficient, with a typical power consumption of only 11 watts per port. This makes it an ideal choice for HPC systems that need to minimize power consumption while still providing high-performance networking.
Compatibility: The MCX516A-GCAT is compatible with a wide range of operating systems, including Linux, Windows, and VMware ESXi. This makes it easy to integrate into existing HPC environments.
