Mellanox ConnectX®-3 EN single port QSFP, 40Gb/s,PCI-E x8

Features:
Mellanox ConnectX-3 EN Gigabit Ethernet Media Access Controller (MAC) with PCI Express 3.0 delivers 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. ConnectX-3 is well suited for blade server and LAN on Motherboard (LOM) designs. Its integrated PHYs, and minimal additional external component requirements were designed for a small PCB footprint. It also has an array of power saving features with real-time monitors that lower total system power usage.
