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.

Interface configuration scenarios

StarlingX supports the use of consolidated interfaces for the management, cluster host, and OAM networks. Some typical configurations are shown in the following table. For best performance, StarlingX recommends dedicated interfaces.

LAG is optional in all instances.
