Dell XGRFF Broadcom 57840S 4 x Ports 10Gb/s SFP+ Rack Daughter Card

Product Description

The Dell XGRFF is a high-performance Network Daughter Card (NDC) that significantly enhances the networking capabilities of compatible Dell PowerEdge servers. This card is powered by the Broadcom 57840S controller, a highly integrated solution designed for demanding enterprise environments. The standout feature of the XGRFF is its quad-port configuration, offering four independent 10 Gigabit Ethernet SFP+ interfaces. This high port density allows for extensive network connectivity, enabling server consolidation, network segmentation, and the aggregation of multiple high-speed links from a single server. This NDC is particularly well-suited for applications that require substantial network throughput and low latency, such as high-performance computing (HPC) clusters, large-scale virtualization deployments, and storage area networks (SANs). The SFP+ ports provide flexibility, allowing administrators to choose the appropriate transceivers (e.g., SR, LR) based on the required distance and fiber type (multi-mode or single-mode). As a mezzanine card, the XGRFF integrates directly into the server's motherboard, optimizing internal space and airflow while providing a robust connection. The Broadcom 57840S controller typically supports advanced features like RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), which can dramatically reduce latency and CPU overhead by enabling direct memory-to-memory transfers between servers. This makes the XGRFF a powerful component for modern, high-performance server infrastructures.
