This dual-port SFP28 PCIe 3.0 x8 card offers exceptional throughput, low latency, and advanced virtualization features, making it ideal for cloud computing, data analytics, storage, and database environments. Its robust hardware-based I\/O virtualization provides scalable and efficient network management, enabling seamless operation of virtualized workloads. The card supports end-to-end Quality of Service (QoS) and congestion control, ensuring reliable data transmission under heavy network loads. It also includes hardware offloads for NVGRE, VXLAN, and GENEVE encapsulated traffic, which accelerates overlay network performance and reduces CPU overhead. Integrating features like PeerDirect communication acceleration and CPU offloading of transport operations, this adapter maximizes application throughput and server utilization while reducing total cost of ownership. The card's compatibility with multiple form factors and adherence to RoHS standards ensures flexibility and environmental compliance, making it suitable for a variety of server configurations. As part of the ConnectX-4 line, this network interface card supports low latency RDMA over Converged Ethernet (RoCE), enabling efficient data transfer for high-performance computing and storage solutions. Its multi-host technology allows connection of up to four independent hosts, providing versatile deployment options. The NVIDIA MCX4121A-ACAT is backed by a one-year limited warranty and is engineered to meet the rigorous demands of modern data centers, offering a reliable, scalable, and high-throughput networking solution.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eVarious form factors available\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRoHS compliant\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eODCC compatible\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHardware-based I\/O virtualization\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnd-to-end QoS and congestion control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHardware offloads for NVGRE, VXLAN, and GENEVE encapsulated traffic\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication offloading\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePeerDirect communication acceleration\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCPU offloading of transport operations\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMulti-Host technology connects up to 4 independent hosts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVirtualization support\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLow latency RDMA over Converged Ethernet (RoCE)\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSingle and dual-port options\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports 1\/10 Gb\/s speeds\u003c\/li\u003e\u003c\/ul\u003e","brand":"NVIDIA SOURCING","offers":[{"title":"Default Title","offer_id":44574774820906,"sku":"MCX4121A-ACAT","price":257.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/1031145647.jpg?v=1784016502","url":"https:\/\/atticusgoods.com\/products\/nvidia-connectx-4-lx-en-adapter-card-25gbe-dual-port-sfp28-pcie-3-0-x8-mcx4121a-acat","provider":"Atticus Goods","version":"1.0","type":"link"}
