Every layer of your cluster is designed to give your team more control, more predictability, and more room to build.
F-01
Run directly on dedicated hardware, with the machine’s capacity focused on your workload. Take control of performance at every stage of your project.
F-02
Dedicated nodes, networking, and storage give your team an exclusive foundation to train, experiment, and put AI to work.
F-03
Your cluster goes through 72 hours of load, memory, network, and thermal testing. Review the results and approve delivery with the evidence in hand.
F-04
Your drivers, your kernels, your tools. Work with Slurm, Kubernetes, or SSH and shape the environment around your model’s needs.
F-05
Spare nodes in the same rack and a 15-minute replacement SLA help reduce the impact of hardware failures on your project.
F-06
Published rates, per-minute metering within your reservation, and 20 TB of outbound data included per node each month. Plan with the costs in view.
