Description

Description PCIe x8 Mellanox Connectx-3 Dual-Port 40G QSFP adapter with PCI Express 3.0 deliver high-bandwidth and industry-leading Ethernet connectivity for performance-driven server and storage applications in Enterprise Data Centers, High-Performance Computing, and Embedded environments. Clustered databases, web infrastructure, and high frequency trading are just a few applications that will achieve significant throughput and latency improvements resulting in faster access, real-time response and more users per server. ConnectX-3 EN improves network performance by increasing available bandwidth while decreasing the associated transport load on the CPU especially in virtualized server environments.

Features

  • High-performance network connectivity: Supports dual-port 40Gb Ethernet and FDR-14 InfiniBand, providing up to 56Gbps of bandwidth for high-performance computing and data center environments.
  • Low Latency and High Throughput: Supports RDMA (Remote Direct Memory Access) and RoCE (RDMA over Converged Ethernet) with latency as low as 1 microsecond, significantly improving network performance.
  • Virtualization Support: Supports SR-IOV (Single Root I/O Virtualization) with up to 127 virtual functions for virtualized server environments and reduced CPU load.
  • Multi-protocol compatibility: Compatible with PCIe 3.0, 2.0, and 1.1, supports multiple network protocols (e.g., TCP/UDP/IP, iSCSI, etc.), and supports multiple operating systems (Linux, Windows, VMware, etc.).
  • Hardware offload function: supports CORE-Direct and GPUDirect technologies, which can offload application loads and improve data processing efficiency, especially suitable for application scenarios such as clustered databases and high-frequency trading.
