Product Description
The Mellanox ConnectX-5 EN adapter, identified by Dell's SKU 540-BCIU, represents a significant advancement in high-speed networking technology. Engineered for the most demanding data center applications, this adapter provides two 100 Gigabit Ethernet ports, each utilizing the QSFP28 form factor. This allows for unparalleled bandwidth and low latency, crucial for tasks such as high-performance computing (HPC), artificial intelligence (AI) and machine learning (ML) workloads, and large-scale cloud infrastructure. The adapter leverages the PCIe Gen4 x16 interface, ensuring that the network throughput is not bottlenecked by the host system's bus. Its advanced capabilities include hardware offloads for various network protocols, such as TCP/UDP/IP checksum calculations and stateless parsing, which significantly reduce CPU utilization. Furthermore, it supports Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) v1 and v2, enabling direct memory access between applications on different servers without involving the operating system, thereby minimizing latency and maximizing efficiency. Beyond its raw speed and offload capabilities, the ConnectX-5 EN adapter is equipped with features designed to enhance storage and networking performance. This includes support for NVMe-oF (NVMe over Fabrics) and other storage acceleration technologies. Its robust design and comprehensive feature set make it a cornerstone for modern, high-performance data centers seeking to maximize application performance and operational efficiency.
