Mellanox ConnectX-3 Dual-Port QSFP+ 40GbE VPI NIC - PCIe 3.0 x8 for InfiniBand/Ethernet with Hardware Offload & RoCE Support

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.
