Mellanox ConnectX-3 Dual-Port QSFP+ 40GbE Network Card - PCIe 3.0 x8 Enterprise/Data Center NIC with Hardware Offload & RoCE Support
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. Specification PCI-Express host interface specification v3.0 x8 and Complete with PCIe2.0 and 1.1 Two 40 Gigabit QSFP+ Ethernet ports Compliant with QSFP+ MSA Spec Rev 1.0 Two QSFP ports supporting FDR-14 InfiniBand or 40Gb Ethernet Support for InfiniBand FDR speeds of up to 56Gbps (auto-negotiation FDR-10, DDR and SDR) Low-profile form factor adapter with 2u bracket Virtual protocol interconnect (VPI) InfiniBand Architecture specification v1.2.1 compliant IEEE Std. 802.3 compliant Compliant with copper cables and optical cables with the use of QSFP connectors.

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.
