PCIe x8 Mellanox Connectx-3 Dual-Port 56G 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.

Key Features

- 1 microsecond MPI ping latency
- Up to 40/56Gb Ethernet per port
- Single and dual port options available
- PCI Express 3.0 (up to 8GT/s)
- CPU transport operation offload
- Application offloading & public and private cloud clustering of database, parallel processing, transactional services, 

   and high-performance embedded I/O applications will realize significant performance improvements, resulting in shorter completion times and lower cost per operation.
