Short answer: yes. Details follow. The SendSMPPassThru interface in SM-HBA could be implemented using usmp(7I), which would make it a peer of libsmp. However, unlike libsmp it provides no marginal utility beyond what usmp(7I) offers, so there is no direct conflict; in fact, it is possible to implement a future libsmp backend that would use this interface on legacy platforms that lack usmp(7I). In no event does the presence of one of these interfaces preclude the other from working properly, and they could coexist in the same application if desired. That said, I have strongly discouraged the SM-HBA project team from implementing this interface in their library, primarily because we do not believe that performing I/O against targets in the storage fabric is in scope for an HBA management library. A similar argument could be made regarding SendScsiInquiry et al vs uscsi(7I). The Unix model is that nexus drivers provide attachment points for devices beyond themeselves, and operations against those devices are performed against the leaf nodes representing them, not by manipulating one of the nexus nodes along the path. Some of the SM-HBA functionality proposed violates this model, while uscsi(7I) and usmp(7I) are consistent with the traditional semantics. But this is orthogonal to libsmp. libsmp is not in conflict with the non-Unix model employed in SM-HBA because it is model-neutral; it allows for arbitrary transport mechanisms including those like SM-HBA that do not follow the traditional model. Note that the semantics of some operations do depend on the transport being used; for example, in the traditional Unix model it is possible that the target leaf node represents a VHCI target with multiple physical paths; in the SM-HBA model this cannot be the case. Whether this is desirable is application-dependent, but in any case libsmp does allow application consumers to open a target using the backend of its choosing (assuming that backend is capable of performing the operation). -- Keith M Wesolowski "Sir, we're surrounded!"
