Descrição de produto
Mellanox ConnectX-5 MCX516A-CCAT 100GbE Dual-Port QSFP28 Adapter Card
High-Performance Ethernet Adapter Card
Dual-Port 100GbE QSFP28 | PCIe 3.0 x16 | Low-Profile | RDMA & RoCE | Smart NIC for HPC, AI, Cloud & Storage
Up to 100Gb/s per port • 750ns ultra-low latency • 200 million messages per second • Hardware offloads for NVMe-oF, OvS, T10-DIF • PCIe 3.0 x16 with embedded switch • RoCE for overlay networks
Product Overview
The Mellanox ConnectX-5 EN MCX516A-CCAT is a high-performance dual-port 100GbE Ethernet adapter card designed for bandwidth-intensive data center workloads including HPC clusters, AI training fabrics, cloud data centers, and software-defined storage. Built on the intelligent ConnectX-5 architecture, this PCIe 3.0 x16 low-profile card delivers ultra-low latency (750ns), high message rate (200 Mpps), and comprehensive hardware offloads that reduce CPU overhead while accelerating virtual switching, NVMe over Fabric, and overlay network processing.
As part of the ConnectX-5 EN series, the MCX516A-CCAT features QSFP28 connectors, supports multiple speeds (100GbE, 50GbE, 40GbE, 25GbE, 10GbE, 1GbE), and enables RoCE (RDMA over Converged Ethernet) for efficient remote direct memory access. With ASAP² (Accelerated Switching and Packet Processing) technology, it offloads Open vSwitch (OvS) data-plane tasks, freeing server resources for application workloads.
Key Features
- Ultra-High Bandwidth: Dual-port 100GbE, aggregate 200Gb/s, PCIe 3.0 x16 interface, 750ns latency, 200M messages per second
- Advanced Offloads: OvS/vRouter offload (ASAP²), NVMe-oF target offload, T10-DIF Signature Handover, RoCE for overlay networks
- Virtualization & I/O: SR-IOV (up to 512 VFs), embedded PCIe switch, header rewrite, NAT hardware offload, flexible match-action tables
- Overlay Networking: Hardware encapsulation/decapsulation for VXLAN, NVGRE, GENEVE, MPLS, NSH -- stateless offloads for SDN environments
- Form Factor & Management: Low-profile PCIe 3.0 x16, NC-SI over MCTP, PLDM monitoring & firmware update, UEFI/PXE/iSCSI remote boot
Technology Deep Dive
Mellanox ASAP² (Accelerated Switching & Packet Processing) -- the MCX516A-CCAT offloads the entire vSwitch/vRouter data path to hardware without modifying the control plane. Flexible match-action tables and a programmable parser enable hardware offloads for current and future protocols, delivering wire-speed packet processing with near-zero CPU load.
RDMA over Converged Ethernet (RoCE) provides low-latency, CPU-bypass data transfers essential for distributed storage, HPC, and AI training. ConnectX-5 adds adaptive routing on reliable transport, out-of-order RDMA support, and burst buffer offloads for background checkpointing.
Embedded PCIe Switch -- the internal switch allows host chaining, elimination of backend ToR switches for storage appliances, and bifurcation capabilities, significantly reducing TCO for rack-scale designs.
NVMe over Fabric (NVMe-oF) Target Offloads minimize CPU intervention for remote NVMe access, delivering high-performance block storage with reduced latency and increased IOPS.
Typical Deployments
- High-Performance Computing (HPC): MPI tag matching, rendezvous offloads, low-latency interconnects for simulation and modeling
- AI & Machine Learning Clusters: GPU Direct RDMA (PeerDirect) communication acceleration for distributed training
- Cloud & Web 2.0 Data Centers: High-density virtualization, SDN environments with VXLAN/GENEVE overlays, OvS offload for NFV
- Software-Defined Storage: NVMe-oF target acceleration, distributed file systems (Ceph, Lustre) leveraging RoCE and iSER
- Telecom & 5G: Ultra-low latency for vEPC, vIMS, and user plane functions (UPF) with hardware service chaining
