Dell 540-BCXW E810 2-Ports 25Gb/s PCIe 4.0 LP GE Network Adapter

Product Description

The Dell 540-BCXW, powered by the Intel E810-XXV controller, is a state-of-the-art dual-port 25Gb/s Ethernet network adapter designed for high-throughput and low-latency networking in modern data centers and cloud environments. This adapter leverages the PCIe 4.0 interface, offering double the bandwidth of PCIe 3.0, ensuring that the two 25Gb/s ports can operate at their full potential without becoming a bottleneck. The SFP28 connectors support 25GbE transceivers, providing flexible and high-speed connectivity options. This adapter is engineered with advanced features to enhance performance and efficiency. It supports Remote Direct Memory Access (RDMA) and RoCE v2 (RDMA over Converged Ethernet version 2), which allow for direct memory access between servers, bypassing the CPU and operating system kernel. This significantly reduces latency and CPU utilization, making it ideal for demanding applications like high-performance computing (HPC), storage networking, and AI/ML workloads. Additionally, it includes support for Single Root I/O Virtualization (SR-IOV), enabling direct network access for virtual machines and improving virtualization performance. The Dell 540-BCXW is designed in a Low Profile (LP) form factor, making it compatible with a wide range of servers, including those with limited internal space. Its robust feature set, including advanced traffic management, Quality of Service (QoS), and precise time synchronization capabilities, makes it a versatile solution for enterprise networking, cloud infrastructure, and high-performance storage connectivity. This adapter is a key component for building next-generation, high-speed network infrastructures.
