ConnectX® EN - Single/Dual-Port 10GbE Adapters with PCI Express 2.0


ConnectX EN Ethernet Network Interface Cards (NIC) deliver high-bandwidth and industry-leading 10GbE connectivity with stateless offloads for converged fabrics in High-Performance Computing, Enterprise Data Centers, and Embedded environments. Clustered databases, web infrastructure, and IP video servers are just a few example applications that will achieve significant throughput and latency improvements resulting in faster access, real time response and increased number of users per server. ConnectX EN improves network performance by increasing available bandwidth to the CPU and providing enhanced performance, especially in virtualized server environments.
