The RAS2 table provides interfaces for platform RAS features. RAS2 offers the same services as RASF, but is more scalable than the latter. RAS2 supports independent RAS controls and capabilities for a given RAS feature for multiple instances of the same component in a given system. The platform can support either RAS2 or RASF but not both.
