Designed for high-performance computing, machine learning, and data analytics, it supports diverse architectures (x86, Power, ARM, GPU) and features an embedded PCIe switch for scalable, reliable networking in demanding environments. ## Description Connecting EN supports two ports of 100GB Ethernet connectivity, while delivering low sub-600ns latency, extremely High message rates, PCIe switch and NVMe over fabric offloads. Connectx-5 providing the highest performance and most flexible solution for the most demanding applications and markets: machine learning, data analytics, and more. Hpc environments connection delivers high bandwidth, low latency, and high computation efficiency for high performance, data intensive and scalable compute and storage platforms. Connection offers enhancements to HPC infrastructures by providing MPI and shmem/ Pgas and rendezvous Tag matching offload, hardware support for Out-of-order RDMA write and read operations, as well as additional network atomic and PCIe atomic operations support. Connecting EN utilizes RoCE (RDMA over converged Ethernet) Technology, delivering low-latency and high performance. Connection enhances RDMA network capabilities by completing the switch adaptiverouting capabilities and supporting data delivered Out-of-order, while maintaining ordered completion semantics, providing Multipath reliability and efficient support for all network topologies including dragonfly and dragonfly+. connectx-5 also supports burst buffer offload for background checkpointing without interfering in the main CPU operations, and the innovative transport service dynamic connected transport (DCT) to ensure extreme scalability for compute and storage systems. Storage environments cnvme storage devices are gaining popularity, offering very fast storage access. The evolving NVMe over fabric (nvmf) protocol leverages the RDMA connectivity for remote access. Connection offers further enhancements by providing nvmf target offloads, enabling very efficient NVMe storage access With no CPU intervention, and thus improved performance and lower latency. Moreover, the embedded PCIe switch enables customers to build standalone storage or machine learning appliances.
