Description
This item is brand-new, factory sealed.
ConnectX-5 EN supports two ports of 100Gb Ethernet connectivity, sub-600 ns latency, and very high message rate, plus PCIe switch and NVMe over Fabric offloads, providing the highest performance and most flexible solution for the most demanding applications and markets: Machine Learning, Data Analytics, and more.
HPC Environments
ConnectX-5 delivers high bandwidth, low latency, and high computation efficiency for high performance, data intensive and scalable compute and storage platforms. ConnectX-5 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.
ConnectX-5 EN utilizes RoCE (RDMA over Converged Ethernet) technology, delivering low-latency and high performance. ConnectX-5 enhances RDMA network capabilities by completing the Switch Adaptive-Routing 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.
