摘要： An apparatus, system, and method are disclosed for device level enablement of a communications protocol. An adapter compatibility module determines an adapter compatibility status for a plurality of host adapters. A positive adapter compatibility status indicates that each host adapter in the plurality of host adapters is compatible with a communications protocol. A processor compatibility module determines a processor compatibility status for one or more processors. The one or more processors coordinate data transfers to and from the plurality of host adapters. A positive processor compatibility status indicates that each of the one or more processors is compatible with the communications protocol. A compatibility summary module determines a compatibility summary for the plurality of host adapters and the one or more processors. The compatibility summary indicates a positive compatibility relative to the communications protocol in response to a positive processor compatibility status and a positive adapter compatibility status.
