Hardware Requirements
=====================
|prod-os| has been tested to work with specific hardware configurations.
If the minimum hardware requirements are not met, system performance cannot be
guaranteed.
See :ref:`StarlingX Hardware Requirements <starlingx-hardware-requirements>` to
review the |prod-long| Kubernetes hardware requirements. In the table below,
only the Interface sections are modified for |prod-os|.

Interface Configuration Scenarios
---------------------------------
|prod-os| 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, |org| recommends dedicated interfaces.
|LAG| is optional in all instances.
