ConnectX®-2 VPI with CORE-Direct Technology


ConnectX-2 adapter cards 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. In addition, ConnectX-2 supports CORE-Direct application acceleration, Virtual-IQ technology for vNIC and vHBA support, and congestion management to maximize the network efficiency making it ideal for HPC or converged data centers operating a wide range of applications.
