Operating a node

This page explains how to setup and run a builder node.

System requirements​

  • Intel TDX-capable CPU
  • 16 cores
  • 32 GiB RAM
  • 2 TB disk storage, min 30K IOPS read/write, 1200MiB/s sequential read/write
  • 1 Gbps Internet access

Cloud hosting​

Currently only Microsoft Azure is supported for hosting, since it's the only provider with an end-to-end working TEE attestations. We are actively working with Google, OVH and other providers, and expect to expand the list of supported cloud providers soon.

Microsoft Azure Cloud​

For Azure, we recommend the Standard_EC16es_v5 instance type.

You'll need to request a quota for "Standard ECEV5 Family vCPUs" (16 vCPUs).

Notes the setup:

  • Azure CLI version 2.65.0 (or later)
  • Storage account: no redundancy necessary
  • Disks: 2TB storage, burst-enabled (needs to support 30K IOPS read/write, 1200MiB/s sequential read/write).

Bare metal hosting​

Bare metal hosting is currently not supported because of two reasons:

  1. Hosting providers only run old BIOS versions
  2. Attestations are not reliable

This presentation has a lot more details about the challenges of TDX attestations on bare-metal servers.

For bare-metal hosting, we are currently working with providers including Google, OpenMetal to resolve any remaining issues with measurements, attestations and BIOS upgrades.

Metrics and dashboards​

Builder nodes provide metrics in Prometheus format.
