Description
The Mellanox ConnectX-4 EN CX414A-LP is a high-performance network adapter engineered to meet the extreme bandwidth and low-latency demands of modern data centers, cloud environments, and high-performance computing (HPC) clusters. This adapter boasts dual QSFP28 ports, each capable of delivering up to 40Gb/s or 56Gb/s Ethernet speeds, providing massive aggregate bandwidth for the most data-intensive applications. The QSFP28 form factor allows for the use of high-density, high-speed optical transceivers, enabling flexible network configurations and connectivity over various distances. Designed with a low-profile bracket, the CX414A-LP is specifically suited for installation in dense server chassis and blade systems where space is a critical constraint. The adapter connects to the host system via a PCI-Express 3.0 x8 interface, ensuring that the network throughput is not limited by the bus speed. This high-bandwidth interface is essential for maximizing the performance of the dual 40/56Gb/s ports, preventing bottlenecks and ensuring efficient data transfer. The ConnectX-4 EN architecture incorporates advanced features to optimize network performance and efficiency. This includes support for RDMA (RoCE) for low-latency memory access, NVMe over Fabrics (NVMe-oF) for high-performance storage networking, and SR-IOV for enhanced virtualization performance. These technologies help offload network processing from the host CPU, freeing up valuable computational resources for applications and improving overall system utilization. The 'EN' designation signifies Enhanced Ethernet capabilities, further optimizing network operations for demanding enterprise workloads.
