Product Description
The Broadcom BCM957414N4140HC is a cutting-edge dual-port 25 Gigabit Ethernet Network Adapter designed to meet the stringent demands of modern data centers and high-performance computing environments. Leveraging the advanced BCM57414 controller, this adapter provides exceptional throughput and low latency, making it ideal for applications such as high-frequency trading, large-scale data analytics, and cloud infrastructure. The adapter connects to the host system via a PCIe Gen3 x16 interface, ensuring ample bandwidth for its dual 25Gb/s ports. Each of the two ports utilizes SFP28 transceivers, allowing for flexible deployment with various fiber optic cabling standards. The adapter is engineered with advanced features to optimize network performance and offload processing from the host CPU. This includes support for Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) versions 1 and 2, which enables direct memory access between network-attached servers, significantly reducing latency and CPU utilization. Furthermore, it supports NVMe over Fabrics (NVMe-oF), accelerating storage access for disaggregated storage solutions. This network adapter is also optimized for software-defined networking and high-performance packet processing through its support for Data Plane Development Kit (DPDK). Its robust feature set, including advanced congestion control, quality of service (QoS) capabilities, and virtual machine (VM) offloads, makes it a versatile solution for demanding enterprise networking needs. The standard PCIe card form factor ensures broad compatibility with most server chassis.
