This is a genuine Mellanox ConnectX-5 Dual Port 100 Gigabit Ethernet (100GbE) QSFP28 PCIe Network Card (P/N: MCX516A-CDAT). 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. Please note: This card is sold without a mounting bracket, making it ideal for users who have an existing bracket or for specialized integration projects.
Key Features
- Dual-Port 100GbE QSFP28: Features two QSFP28 ports, each supporting 100 Gigabit Ethernet, providing massive aggregate bandwidth (200Gb/s total) and enabling high-density, ultra-fast network connectivity.
-
Mellanox ConnectX-5 Controller: Powered by the industry-leading Mellanox (now NVIDIA) ConnectX-5 controller, renowned for its superior performance, low latency, and advanced feature set.
- PCIe Interface: 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.
-
RDMA over Converged Ethernet (RoCE) Support: Enables direct memory access between servers, bypassing the CPU, which drastically reduces latency and boosts throughput for data-intensive applications.
- NVMe over Fabric (NVMe-oF) Offload: Provides hardware offloads for NVMe-oF, accelerating access to remote storage with local-like performance.
- Advanced Hardware Offloads: 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.
- Virtualization Acceleration: Features SR-IOV (Single-Root I/O Virtualization) and other virtualization enhancements to maximize network performance and resource utilization in virtualized environments.
-
Ultra-Low Latency: Engineered for industry-leading low latency, crucial for high-frequency trading, real-time analytics, and other latency-sensitive applications.
-
No Mounting Bracket: This specific offering does not include a metal mounting bracket, requiring users to source one separately or for specific integration needs.
