10 Gigabit Ethernet Host Channel Adapters - Read This First: Documentation Roadmap

Mellanox ConnectX Technology - 10 Gigabit Ethernet

HP and Mellanox HCAs based on Mellanox ConnectX technology deliver high-bandwidth and

industry-leading 10GigE 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.

Features of Mellanox ConnectX HCAs include:

 Dual-port 10GBASE-SFP+ NIC

 PCI Express 2.0 x8 (1.1 compatible)

 Support for Data Center Ethernet (DCE)

 Hardware Offload of Fiber Channel over Ethernet (FCoE)

 Support for Single Root - I/O Virtualization (SRIOV)

 Traffic steering across multiple cores

 TCP/UDP/IP stateless offload in hardware

 Intelligent interrupt coalescence

 Hardware-based I/O virtualization

 Advanced Quality of Service

 Full support for Intel I/OAT

The following table provides links to the documentation and specifications for the 10 Gigabit

Ethernet HCAs used in HP High Performance Computing configurations.
