HP InfiniBand Host Channel Adaptors based on Mellanox ConnectX-2 Technology - Read This First: Documentation Roadmap

Mellanox ConnectX-2 Technology

HP InfiniBand HCAs based on the Mellanox ConnectX-2 technology with Virtual Protocol

Interconnect (VPI) provide the highest performing and most flexible interconnect solution for

Enterprise Data Centers, High-Performance Computing, and Embedded environments. Clustered

data bases, parallelized applications, transactional services and high-performance embedded I/O

applications will achieve significant performance improvements resulting in reduced completion time

and lower cost per operation. ConnectX-2 with VPI also simplifies network deployment by

consolidating cables and enhancing performance in virtualized server environments.

The key features of Mellanox ConnectX-2 include:

 Virtual Protocol Interconnect

 1us MPI ping latency

 Selectable 10, 20, or 40Gb/s InfiniBand or 10GigE per port

 Single- and Dual-Port options available

 PCI Express 2.0 (up to 5GT/s)

 CPU offload of transport operations

 End-to-end QoS and congestion control

 Hardware-based I/O virtualization

 TCP/UDP/IP stateless offload

 Fibre Channel encapsulation (FCoIB or FCoE)

 RoHS-R6
