Automation Below Kubernetes
NetBox-backed inventory plus automated SONiC networking, PXE boot, host setup, and current ROCm drivers, so orchestration is not the first layer.
Isolated KVM Instances
NUMA-balanced KVM virtual machines with direct GPU access and private isolated networking to avoid noisy neighbors.
High-Speed Fabric
8x400G RoCEv2 per chassis plus 100G internet and unlimited bandwidth.
Ready-to-Use Images
Ubuntu options with ROCm, Docker, and optional K8s/Slurm/Ray installs via cloud-init.
