Mellanox Introduces ConnectX-4 Adapter

Today Mellanox Technologies introduced the ConnectX-4 Adapter, a single/dual-port 100Gb/s Virtual Protocol Interconnect (VPI) adapter, the final piece to the industry’s first complete end-to-end 100Gb/s InfiniBand interconnect solution. The ConnectX-4 will provide high-performance and low latency needs for high-performance computing (HPC), cloud, Web 2.0, and Big Data applications.

With the explosion of data, companies need to meet the demands of this growth. The introduction of 100Gb/s interconnects will help companies keep up with the growing demands for data processing and retrieval. Doubling the throughput of the previous generation, the ConnectX-4 will give enterprises a scalable, efficient, high-performance solution. The ConnectX-4 can deliver 10, 20, 25, 40, 50, 56 and 100Gb/s throughput supporting both the InfiniBand and the Ethernet standard protocols, and the flexibility to connect any CPU architecture – x86, GPU, POWER, ARM, FPGA and more. Mellanox claims performance of 150 million messages per second, 0.7usec of latency, and smart acceleration engines such as RDMA, GPUDirect and SR-IOV.

Mellanox will offer complete end-to-end 100Gb/s InfiniBand solution, including the EDR 100Gb/s Switch-IB InfiniBand switch and LinkX 100Gb/s copper and fiber cables. For Ethernet-based data centers, Mellanox’s ConnectX-4 provides the complete link speed options of 10, 25, 40, 50 and 100Gb/s. Supporting these speeds, Mellanox offers a complete copper and fiber cable options.
