Networking topologies

DriveNets AI Fabric includes a solution for any part of the networking fabric, including:

Scale-up networking – An Ethernet based (ESUN-SUE/T) solution for rack-scale scale up networking. Open-standard, low latency and high efficiency solution for AMD-based architectures.
Scale-out networking – Fabric-scheduled Ethernet: A cell-based fabric with standard Ethernet connectivity to endpoint ensures the highest performance networking for any GPU and any NIC.
Scale-out networking – Endpoint-scheduled Ethernet: Standard Ethernet Clos architecture with endpoint scheduling performed in the NIC, with multiple NIC providers supported (AMD, Broadcom) and standard-based packet spraying (Ultra-Ethernet)
Scale-across – A connectivity solution for back-end networking across multiple datacenters, suitable for distances of up to 100km.
Front-end and storage networking – a unified fabric for storage network and front-end connectivity

Orchestration

DriveNets provides an end-to-end software stack, including:

DNOS: Network operating-system that runs on multiple hardware options
AI Cluster Orchestrator: a lifecycle orchestration system with engines tailored for:

Provisioning: a bring-up, configuration and scaling tool that automatically discovers and provisions the entire AI infrastructure, including servers, NICs, and network components, ensuring complete visibility and seamless deployment of an optimized reference architecture.
Benchmarking: an end-to-end cluster performance validation engine that streamlines cluster benchmarking by executing RDMA, RCCL/NCCL, and representative AI workloads to ensure the environment operates at peak performance
Ongoing management: a day-n cluster manager
