# DigitalOcean Gradient™ AI Bare Metal GPUs Limits

DigitalOcean Gradient™ AI Bare Metal GPUs are dedicated, single-tenant servers with 8 GPUs of various models that can operate standalone or in multi-node clusters.

- Bare metal GPUs are not available for on-demand provisioning through the DigitalOcean Control Panel, API, or CLI. To purchase and provision bare metal GPUs, [contact our sales team](https://www.digitalocean.com/products/bare-metal-gpu?referrer=pdocs&utm_campaign=digitalocean-gradient-ai-bare-metal-gpus-limits#sales-form), who can finalize pricing and deployment with you.
- Bare metal GPUs are currently available only in the AMS, NYC, and ATL regions. For more information about datacenter availabilities, see our [availability page](https://docs.digitalocean.com/products/bare-metal-gpus/details/availability/index.html.md).
- We do not offer direct IPMI access to bare metal GPUs.
- By default, there are no firewalls or gateways in front of bare metal GPUs. We recommend using [UFW](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-ubuntu) to protect bare metal GPUs on the public interface.
