System Hardware Requirements

StarlingX has been tested to work with specific hardware configurations. For more information, see Self Validated and Certified Hosts.

If the minimum hardware requirements are not met, system performance cannot be guaranteed.

All-in-One Simplex

The recommended minimum hardware requirements for bare metal servers for various host types are:

Minimum Requirements
