Designed for extreme performance and scalability, the ConnectX-5 series adapters are the backbone of modern data centers, High-Performance Computing (HPC), and artificial intelligence (AI) infrastructures. This dual-port adapter delivers unparalleled 100GbE throughput and ultra-low latency via its QSFP28 interfaces, along with a robust PCIe Gen3 or Gen4 host interface (depending on specific model variant and server compatibility). It provides advanced hardware offloads for RDMA over Converged Ethernet (RoCE), NVMe over Fabric (NVMe-oF), and other crucial networking functions. \u003cb\u003ePlease note: This card is sold without a mounting bracket\u003c\/b\u003e, making it ideal for users who have an existing bracket or for specialized integration projects.\u003c\/p\u003e\n\n\u003chr\u003e\n\u003cp\u003e \u003c\/p\u003e\n\n\u003ch3\u003e\n\u003cb\u003eKey Features\u003c\/b\u003e \u003c\/h3\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cb\u003eDual-Port 100GbE QSFP28:\u003c\/b\u003e Features two QSFP28 ports, each supporting 100 Gigabit Ethernet, providing massive aggregate bandwidth (200Gb\/s total) and enabling high-density, ultra-fast network connectivity.\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e\u003cb\u003eMellanox ConnectX-5 Controller:\u003c\/b\u003e Powered by the industry-leading Mellanox (now NVIDIA) ConnectX-5 controller, renowned for its superior performance, low latency, and advanced feature set.\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cb\u003ePCIe Interface:\u003c\/b\u003e Utilizes a high-bandwidth PCI Express interface (Gen3 x16 or Gen4 x8\/x16 depending on variant) to support the demanding data rates of 100GbE, minimizing bottlenecks.\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e\u003cb\u003eRDMA over Converged Ethernet (RoCE) Support:\u003c\/b\u003e Enables direct memory access between servers, bypassing the CPU, which drastically reduces latency and boosts throughput for data-intensive applications.\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cb\u003eNVMe over Fabric (NVMe-oF) Offload:\u003c\/b\u003e Provides hardware offloads for NVMe-oF, accelerating access to remote storage with local-like performance.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cb\u003eAdvanced Hardware Offloads:\u003c\/b\u003e Includes extensive stateless and stateful offloads (e.g., TCP\/UDP\/IP checksum, LSO, LRO, VXLAN, NVGRE, Geneve) to significantly reduce CPU utilization and improve application efficiency.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cb\u003eVirtualization Acceleration:\u003c\/b\u003e Features SR-IOV (Single-Root I\/O Virtualization) and other virtualization enhancements to maximize network performance and resource utilization in virtualized environments.\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e\u003cb\u003eUltra-Low Latency:\u003c\/b\u003e Engineered for industry-leading low latency, crucial for high-frequency trading, real-time analytics, and other latency-sensitive applications.\u003c\/p\u003e\n\t\u003c\/li\u003e\n\t\u003cli\u003e\n\t\u003cp\u003e\u003cb\u003eNo Mounting Bracket:\u003c\/b\u003e This specific offering \u003ci\u003edoes not include a metal mounting bracket\u003c\/i\u003e, requiring users to source one separately or for specific integration needs.\u003c\/p\u003e\n\t\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Mellanox","offers":[{"title":"Default Title","offer_id":54736761454665,"sku":"MCX516A-CDAT","price":474.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/3868\/3209\/files\/b6aea7d5-b89e-5431-abb8-daad74bb7e20.png?v=1758660478","url":"https:\/\/parts.theserverstore.com\/products\/mellanox-connectx-5-dual-port-100-gigabit-ethernet-100gbe-qsfp28-pcie-network-card-no-bracket-included-p-n-mcx516a-cdat","provider":"The Server Store Parts","version":"1.0","type":"link"}
